Dual Boot Windows and Linux: Single and Multiple Hard Drives

April 9, 2008 by gothamange

The internet is full of technical articles, many of which are way too complicated for the average computer user who just wants to solve a simple problem. If you pay close attention, the internet is also a place where the gurus spend a lot of time yelling for help in discussion boards and forums. So don t feel bad, nobody has all the answers.

So you want to dual boot Windows and Linux on the same computer it is really quite easy. I only have enough room here to tell you the most common way to do this on a single hard drive or using multiple hard drives. Obviously then, there are many ways to get the job done, but there are some critical things you should know. Let s start with some critical information.

Windows and Linux: Same Hard Drive
The windows operating system MUST occupy the master boot record (MBR). Linux, on the other hand does not have to. In this scenario, you must install windows first! After Windows has been successfully installed, then you can install Linux. This is critical! The Linux boot loader is called GRUB. When you install Linux MAKE SURE YOU DO NOT INSTALL THE LINUX BOOT LOADER TO THE MBR.

Configure the Windows Boot Loader: A Two Step Process
It is also possible to use GRUB to dual boot Windows and Linux on the same drive but this is a bit more complex the Windows boot loader will get the job done. In the following commands, you will create a copy of the Linux boot sector and then save it in a file in the top level directory under Windows (C:).

Step 1: Linux
From the shell in your Linux installation (boot from your installation disks):
Execute the following shell command, replacing /dev/hda3 with the location of your Linux boot partition.

shell dd if=/dev/hda3 of=/bootsect.lnx bs=512 count=1

Copy the new file bootsect.lnx to a floppy disk and reboot to Windows.

Step 2: Windows
Copy bootsect.lnx to C: in Windows. Then execute the following command at the DOS prompt.

C:> attrib -H -R -S boot.ini

Edit boot.ini so that the first two lines are:

[boot loader]
timeout=30

After the last line, add:

c:bootsect.lnx= Start Linux

That s it, you are done! Reboot your machine and you will see a menu allowing you to select either Windows or Linux. Congratulations.

Windows and Linux: Two Hard Drives
This is also quite easy. In this case, you will boot to the Linux drive. We will add Windows to the Linux boot loader (i.e., GRUB). GRUB is my favorite boot loader.

Edit the /boot/grub/grub.conf file. One of the very first lines should contain:

timeout=30

After the last line add:

title Start Windows
map (hd1) (hd0)
map (hd0) (hd1)
rootnoverify (hd1,0)
makeactive
chainloader +1

Reboot your machine to the Linux drive and you will see a menu allowing you to select between Linux or Windows. Nice work!

This article is obviously short and does not include any explanations of how these commands work. There are variations on what I have shown here depending on your hardware setup, but I believe that these are the most common and should get the job done nicely. I would be happy to direct you to additional resources if this does not work for you.

How To Find Tech Support For Your Computer Printers

April 7, 2008 by gothamange

Computers are becoming commonplace in homes and offices around the world. The problem is that most people know so very little about their computers, that when something goes wrong, they do not know how to begin the troubleshooting process.
The ugly truth is that we could opt to call the technical support phone number that came with the computer, but you never really know what you are going to get at the other end of the phone. You could literally spend several hours just waiting to get to a technician, and then once you have the human on the line, there is just as good of a chance that they will not have a clue, as there is that they will find your solution.
I know this because I used to work in a computer technical support call center. You would be amazed who can pass as a technician! For most new hires, the only pre-qualifying knowledge that is necessary is being able to navigate the current Windows Operating System.
Management feels that if you can navigate Windows, then you can navigate the database to dig up a solution. The problem with this kind of thinking is that the person at the call center is often lost to find a solution that is not yet in the database.
Of course, all front line technicians have a help desk to call, but in my own experience, help desk posts were assigned based on politics and not technical knowledge. We ended up with some real idiots at our help desk. Call those people once or twice, and you will eventually decide that you stand a stronger chance to succeed on your own, than you would be able to accomplish going upstream in the support systems.
The Business of Printing Support
Fortunately, computer printers do not break that often. But when they do, troubleshooting can be a painful process.
There are some basics that you can cover to streamline the troubleshooting process.
Be forewarned that if you ever crack the case of your printer, you should make darn sure to disconnect the power source before you do so. Printers that are connected to a power supply can actually charge you up with enough current to kill you. Don t take chances with your life.
Long before you get to the point of trying to crack the case to reach the internals, there are several troubleshooting steps you can take.
* Always check your power supply to see that you have a good, solid connection. I know that it seems the most logical step to take, but you might be surprised how often a powerless machine is discovered to be an unplugged machine.
* If the printer has power going to it, then turn off the machine and then turn it back on. Each printer has an internal brain in it. Removing power temporarily from the machine will force the computer chip inside of the printer to reset. Often times, this will solve any issues.
* Make sure that your printer cartridge is properly seated. Make sure the cartridge is in the printer the way that the manufacturer intended.
* Use the printer s “self-test” feature. The manufacturer has included this to help you to eliminate common printing problems.
These four steps will help you to overcome the problems most commonly associated with printers.
For a complete breakdown of generic troubleshooting steps, the following URL points to the most comprehensive and easy-to-follow checklist I have seen: http://www.5starsupport.com/info/printer.htm
Drivers Are the Software Applications That Power Printers
A driver is the software package that enables your printer to communicate with your computer s operating system, and vise versa.
The manufacturer of your printer sent out a software disc with the printer. On this disk, you can find the default driver for that printer.
As computing evolves, printer manufacturers upgrade their drivers to either improve the printer s performance or to keep up with changing Operating Systems.
Of course, you could go to a website that has been established to give you a one-stop shop for finding hardware drivers online. A couple of the most common sites of this type are:
* http://www.windrivers.com
* http://www.driverguide.com
While these global sites are good, they don t always deliver the most up-to-date drivers that are available from the manufacturer.

The Unseen Printing Industry
Printers are cheap to replace as a general rule. If you have a printer whose transport motor failed, it might actually be cheaper to throw the printer in the trash and replace it with a new one. Sure, it might seem logical to buy a new motor and to replace the dead motor, but do compare pricing options first.
What most people fail to realize is that the printer companies are not making their money on manufacturing and selling printers. Sure, they do still make a profit when you buy your printer, but that is not the activity that keeps their stockholders happy.
When buying a printer, it really does make a lot of sense to compare the prices of replacement cartridges before you buy the printer. I bought a laser printer one time and was really excited about my new tool that is until I priced a replacement cartridge for it. $180 a pop for a remanufactured laser printer cartridge. Egad! That was more than I paid for the printer. I even bought a replacement printer for less money.
Sometimes, there is a challenge to find your printer toner cartridge at your local shopping center. With so many varieties of printers out there, most supply stores will not keep all of the various replacements on hand.
While it might make sense to go to the manufacturer website to buy replacement toner kits and cartridges, they generally charge a premium for those replacements. The manufacturer premiums can sometimes be as much as three times more expensive than what you can buy from a good third-party provider — even when that third-party provider bought the replacement from a middleman. It is just like the airline industry. It is often cheaper to buy your plane tickets from a travel company than from the airline itself.
With the printer currently sitting on my desk, I save $14-$17 on my color cartridge by buying my printer supplies from http://www.tonerr.com. By using this third-party provider, I save $14 against the manufacturer s website, and I can save $17 against Wal-Mart s prices. On the black toner cartridge, I still save money buying from http://www.tonerr.com. I can save $5 against buying the replacement from the manufacturer, and I can save $6 against buying from Wal-Mart. And, we have been trained to believe that Wal-Mart always has the best prices. Imagine that.
When it is time to buy a printer, never think that the manufacturer has your best interests at heart. They are in this business to make the most money they can, period.

Increasing Manufacturing Profits Through Precision Pricing

April 7, 2008 by gothamange

Manufacturers face an array of complex challenges including intense competition, increasing costs, and accelerated product life cycles. Technology investments in enterprise systems such as ERP, SCM, PLM, and CRM over the last ten years have helped to rein in operating costs and increase corporate agility. As adoption of these capabilities has become widespread, they no longer provide competitive advantage. However, the resulting quantity and quality of data they produce have set the stage for business intelligence applications that leverage this data to analyze and optimize business performance.

One of the functional areas best-suited for a quantitative approach is pricing. Data-driven customer segmentation and optimization models can recommend prices that are much more profitable than those currently in market. This pricing science can be easily applied through analytical and execution applications, enabling smarter decisions and better execution across all business functions related to pricing. Given the current state of pricing practices and its considerable impact of financial performance, the potential benefits of pricing initiatives are enormous.

Moreover, manufacturers broad product lines, numerous customers, and negotiated sales model combine to create a business environment that is very conducive to a science-guided approach to pricing. Early adopters pursuit of an intelligent pricing advantage has led to the development of commercial solutions. Having worked with manufacturers for years, Zilliant s industry-specific pricing applications provide the fit and flexibility that they need.

Until now, only a limited number of success stories have been made public due to the sensitive and strategic nature of pricing practices. This lack of publicity belies the growing use of advanced pricing techniques and applications in business-to-business markets including manufacturing. As the leading practitioners have achieved significant, measurable benefits, however, more and more manufacturers are investing in pricing-related initiatives. As a result, the industry is experiencing a steep adoption curve similar to what was previously seen in travel, hospitality and retail.

Most manufacturing companies are very familiar with the power of process automation to improve business performance. However, many are just beginning to exploit the potential of applied business intelligence applications that harness data from operational systems to improve decision-making across the enterprise. A few of these companies have embraced sophisticated analysis and optimization systems so deeply that some management strategists have dubbed them analytics competitors .

Regardless of how widespread a company s use of analytics is, using more quantitative approaches to pricing can deliver significant financial gains. Many companies current pricing processes are manual and largely ad hoc, resulting in poorly-priced deals that leave significant margin on the table. In most cases, price, discount, and other margin-driving terms are arbitrarily based on precedent and circumstance rather than empirical analysis and strategic intent. Even companies that apply pricing principles manually, e.g. basic price segmentation, would benefit greatly from more precise price differentiation that can only come from advanced quantitative models and optimization techniques.

Following the example set in other industries such as airlines and hotels, some manufacturers began pursuing pricing initiatives years ago. Their focus has been in two areas: controlling discounting and applying optimization techniques to exploit price elasticity. These early adopters realized that the sooner they started, the greater the financial benefit. In almost every case, these projects have exceeded their projected return on investment, in some cases delivering tens of millions of dollars of incremental profit. Learning of these compelling successes, many more companies in a wide range of manufacturing sectors (industrial, high tech, chemical) are confidently pursuing similar pricing initiatives.

So what are some of the key lessons learned? And why did it take so long for manufacturers to begin to adopt quantitative pricing methods? Answering these questions requires an understanding of manufacturing s three most pressing pricing challenges and the opportunities attendant in overcoming them. The answers also point to key capabilities are required to capitalize on these opportunities.

1. Ad Hoc Pricing Facilitates Price Differentiation: Diversified manufacturers typically have extensive product portfolios and very sizable customer bases. After taking into account all price-related variables (e.g. costs, contracts, discounts, volume agreements, customizations, shipping, etc.), the total number of unique prices in market at any one time can easily exceed 100,000. With so many products, exceptions, and changes over time, it is no wonder that manufacturers price points and margins vary widely across their business. In fact, some manufacturers struggle with merely calculating prices that are correct , i.e. are in accordance with their numerous price lists, policies, and contracts, let alone differentiating prices to maximize margins and overall profits.

Fortunately, this complexity can be not only managed, but also exploited. Information systems designed to allow companies to calculate correct prices are widely available, often as functional modules within the order management products marketed by ERP and CRM vendors. Better still are integrated price segmentation, optimization and enforcement applications from best-of-breed pricing application vendors like Zilliant. Their advantage is that they allow manufacturers to operationalize differentiated, profit-maximizing prices by employing science-based segmentation and optimization capabilities.

The scientific foundation of price differentiation is segmenting customers by the price sensitivity and using each price segment s unique sensitivity to set prices on future deals. Figure 2 shows examples of how companies have dramatically increased the number of actionable segmentation variables they use to set differentiated prices.

Only by identifying and acting on the variables that most affect customers buying behavior can companies fully capture the value of these purchases as incremental margin on every deal.

2. Better Data Quantity and Quality Available for Quantitative Applications: Managing all of these pricing inputs and calculations typically involves a number of disparate transactional and price administration systems. Additionally, most manufacturers now have some type of customer relationship management (CRM) software in place for managing customer, sales opportunity, and competitive data, adding to the multitude of isolated systems.

Fortunately, while data collection and integration can be difficult, this challenge is now more tractable than ever. Many companies have already rationalized numerous legacy systems into a few data-rich enterprise applications, and have begun to aggregate transactional and CRM data into central repositories. Even when data remains scattered across multiple systems, improved APIs and integration tools have simplified its retrieval. In all, companies now are much better able to aggregate and analyze the data needed to define price segments and their relative profitability.

Even after aggregating all available data, quantity and quality can still be a challenge. Many products are slow moving , producing sparse transactional history. And most companies do not track quotes that do not become orders, valuable data for determining price sensitivity. Overcoming these limitations is crucial to maximizing the profit potential from segmentation and optimization, and is a major advantage offered by Zilliant.

3. Informed Negotiations Increase Profits: Last but not least, the negotiating behaviors of sales personnel and channel partners play a major role in determining the profitability of deal outcomes. Uninformed decisions related to discounts and other costly terms is a major source of revenue leakage in most companies.

The good news is that the most powerful negotiating tool available is information. Giving sales people reasonable price recommendations based on quantitative information about what similar customers paid under similar circumstances immediately improves results. In addition to better market information and price recommendations, incentives also have a powerful effect on sales representatives discipline and confidence. And when management deems that an order deserves an exception to standard discounting policy, the ability to evaluate different scenarios based on their relative profitability ensures must win deals helps limit the overall financial impact.

With a rich pool of data at-hand and proven applications to exploit this data, there is no better time for manufacturers to invest in pricing initiatives. And there is no better partner than Zilliant. Working with manufacturing companies like yours, we have made a significant investment in the products and people that make up our total solution.

Google Webmaster Tool For SEO Experts

April 5, 2008 by gothamange

I just finished watching a video that shared some updates on what s happening at the major search engines lately. Since webmasters are always interested in learning more about search engine optimization (SEO) techniques, I thought it would be good to share a neat trick using Google s webmaster tools.

The first time I heard about Google webmaster tools, it was known as Google sitemaps. That was very little that we can do with it, except upload a sitemap so that a new site can be included in Google s index quicker. After toying with it for a couple of days, I find it a hassle to generate those sitemaps. If a website is destined to grow, that would mean taking up more time submitting those sitemaps. Strapped for time as it is, I figured it would be better to just concentrate on building more content for my websites.

It s still hard for me to refer to Google s new toys with a new name but I guess it s a much more suitable name, now that so many new tools have been added. To begin using the tool, login to the control panel using a valid Google username. If you do not possess one, just sign up at the site google.com/webmasters. After logging in, enter the URL that you would like to obtain more information about. You ll be required to verify that you own the site. To do so, you can either add a META tag or upload a HTML file. Verification is instant and you ll see your verification status as Verified if it s successful.

Upon verification, all kinds of interesting tidbits about your site will be available. The one that interests me most is the page analysis (Statistics > Page Analysis). This allows any webmaster to view information about external links. In other words, Google learns about a website s general theme from external text links. You ll be able to see all the keywords that other people have used in the text links that link to your site.

Many webmasters have already discovered the “secret” that anchor texts should be used in text links. Anchor texts look something like Anchor texts. There are many ways to obtain keyword targetted external links. One popular way is to submit to web directories.

In many instances, web directories allow webmasters to submit their sites for free. Some web directories become more established and may charge a small fee for a site submission. However, fees are usually one-time payment and are better deals compared to text links that require monthly subscription.

So, take a look around the webmaster community and spot SEO friendly web directories and start submitting some links. Your competitor may be doing exactly the same thing and I don t know about you but I hate to lose. See you at the number 1 spot!

Now You Can Create Your Own Desktop Icon!

April 3, 2008 by gothamange

There are some people who are so much effort into adapting their desktop computer, as far as the tips of the decorating their desks or even rooms. I have personally seen friends of mine for hours searching for the perfect desktop icon, the other point or another that they can be observed and their childhood in the& 39;70s. And no matter how rare or obscure the desktop icon, someone, somewhere in this universe of us has at least a pirate version of it, often as part of a theme. There are countless desktop icons floating around, that the number will probably never be known.

Certainly the best way to secure all your symbols as part of a desktop theme. Desktop themes with icons, background images, event sounds, and even color schemes all on the same topic to convert your desktop in a seamless color-filled, decorative scheme. For example, I used to have a Scooby-Doo theme, complete with a desktop icon for each character. There was even a secret machine desktop icon with little rolling wheels, informed me if the computer was a little busy loading. The coolest thing about the desktop theme was the small " zoinks " sound from that every time an error occurred. And since I was using Windows, which happens quite often. The Scooby-Doo Desktop icon itself was so chic IMHO.

If (and this is a real IF), you really have a thing for the desktop icons, the best thing to do is to create them! How funny is that?! You can easily get a desktop icon download Creator, and you would not believe how easy they are to make. Each Desktop icon is really only a very small, relatively low-resolution image. This means that you are probably the perfect desktop icon with a little imagination and creativity, and an hour or two of your time.

I was also said that some desktop icon creator can shrink photographs in desktop icons for you, saving you valuable time it takes to create them, but I do not know whether they actually exist. The best thing is to try, even if you are really interested. Like any other program, the desktop icon creator software can be found in either free of charge or trial versions (g), so that it& 39;s not so difficult to get hold of and run with. And then you have the perfect desktop icons, which you have always dreamed of!

Cisco CCNP / BSCI Tutorial: The BGP Attribute NEXT HOP

April 1, 2008 by gothamange

When I study to test bsci a way to earn a certificate ccnp your own, you have got an MA in use bgp attributes. These attributes allow you to manipulate the road, or roads, which will bgp particular use to reach the destination when multiple paths to the destination exist.
in free bgp this educational program, and we are going to look at next hop attribute. You can think " Hey, how can we hold this feature to be? & Quot; it is not very complicated at all, but this is Cisco, and there happened to be at least one unusual detail, Alice well?
the next hop feature is simple – and this shows feature coming – leap address intellectual property that should be taken to reach a destination. In the following example, Rand is the focus of the course and R2 and R3 are the spokesman. All three tracks in bgp as 100, with the rand to do with peer both R2 and R3. There is bgp between R2 and R3.
r3 was the announcement by the network 33.3.0.0 / 24 bgp through, and we see value coming – leap to feature in the Rand Show output of IP bgp:

r1 Show IP version bgp
bgp Table 1, the local track ID 1.1.1.1
status codes: S suppressed, and discouraged d, h history, * valid, > best, and I –
origin procedure codes: I – igp, e – he added,? — Incomplete
network next leap metric locprf weight road
* > i33.3.3.0/24 172.12.123.3 01000 I

in this example, the next – a leap is 33.3.3.0/24 network 172.12.123.3. Simple, right?
the issue with the next – leap feature comes in the way when he declares told bgp peers. If they are in separate from R3 and R2 Rand, Rand then declared the road to R2 with the next – leap to a feature 172.12.123.3. When the speaker announced bgp route for ibgp nobles that were originally learned from ebgp peer jump ahead – is to maintain the value.
here, all three tracks as they are 100. How will the next – be a leap to a Rand when he declares the way to ibgp neighbor R2?
r2 show IP bgp
there there will be the next leap – a cursed by R2, because the road will not appear on the R2. By default, bgp will not announce a route spokesman told ibgp neighbors, and if the way I learned from the last ibgp neighbor.
luckily For us, there are several ways around this rule. The most common is the use of reflectors road, we will look at the future of rrs bgp free education programme. lakia nitro

Computer Consulting: A Business of Time and Sweat Equity

March 30, 2008 by gothamange

Building a computer consultancy requires a lot of time. It applies from the session and he shook many hands. They need too much & 39; monitoring telephone conversations. Display ads and mailings drops and other marketing measures do not replace the calls d & 39; a potential customer for & 39; attempt, a person-to-person connection. Because of the necessary hand-in the time, you should be realistic in relation to what & 39; so that the computer-consulting company. Not
Franchises Silver Raviers
Even serving with the franchise, the franchisor & 39; n is not handed over a list of customers on a plateau d & 39; money. If you wish to receive a list of customers d & 39;, not to buy a franchise: You need & 39; buy d & 39; ongoing business. And, of course, & 39; purchase of electricity & 39 d & 39; business is still higher capital more openness. D & 39; buy even a small, prosperous company in the IT consulting cost a few hundred million dollars to a few million dollars almost a multiple of annual sales.
What Your Computer Consulting Business Start-up costs?

In many cases, you can with the work from your home office. The cost for the foundation are certainly with a higher franchise.
Franchises they are not for control freaks
Another negative for the exemption can be a loss of control. You have to do things d & 39; in any way and according to the rules. And you can not go too far, the outside & 39;.

The Bottom Line on Computer Consulting
Computer hearing has some different options for start-up. You can use an independent company, the acquisition & 39 d & 39; liberation or d & 39; buy a company, if you want to start from zero or to a list of customers.

How to Recover a Quick Erased CD-RW versus DVD-RW

March 19, 2008 by gothamange

Due to the different standards for rewritable optical media, especially CD-RW, DVD-RW and DVD + RW, the state of the media after a quick deletion is different. This status determines whether it is possible or not to recover data with any data recovery software tool for matter.
There is that some of the complexity and you need to read this article twice Mainly because of ;-) various exemptions and the role of software vs. hardware.
First perhaps the difference between a full delete, and a quick drive to erase:
I & 39; m intentionally drive level to mention it because in most cases the drive, a blank command executes provided by the software. So for the software, it is more or less a " Hit and Run " command. Send it down and walk away or survey the drive to a full command ready.
When erased on re-writable optical media then the entire surface of the CD / DVD is over-written with a neutral pattern (all zeros or all or 0xAA The fact that something similar). The result is that all data that once was, is now gone forever. There are no magic tricks to find the data ever again, the old contents were completely destroyed, not even in the high-end laboratory with geniuses at work, it would be possible to recover the data. In addition, the CD / DVD structures on the inside of rings, all drives used to determine the layout of the media, has been updated to resemble blank media. All references to the rails and the meeting, there is now once gone.
A quickly delete itself quickly (mind …) and therefore the disc & 39; s main data area remains untouched, or at least essentially unaffected. All (or most) data remains on the disc. What has changed is the disc structures again, on the inner side of the rings media. All references to the rails and the meeting will be deleted and in the media is left in a state that seems as empty media for a CD / DVD burner (in most cases … read on).
So when the largest part of the data, it is still for a quick delete … What is the problem then you ask? Well, the biggest problem for a CD-RW and DVD-RW (DVD hyphen / minus RW).
As I explained before, during a quick deletion to the CD / DVD drive on the structures will be changed so that a CD / DVD drive as a blank looks again then. And that& 39;s the big problem, a blank CD / DVD – as far as the drive is concerned – is a blank CD / DVD drive, and they will not allow anywhere to read on the DVD. All read commands not immediately drive error. The drive does not even try reading at the desired locations. At this point, the drive is the limiting factor, there is no way of getting around this, as it is not possible to say that the drive is available in different media, as that which sees the drive for themselves (*).
The only way (*) To work around this problem is to send the disc to a (possibly expensive), the recovery laboratory have the right equipment to deal with it. Since this is a problem of limited hardware, a few laboratories have tailored hardware with this particular problem.
(*) If I notice there& 39;s more interest in this then I will dedicate another article to this problem, especially as a handy man with too much free time might try to make a few things.
There is a big exception for DVD-RW (CD-RW) to delete it, even if the software in the spirit of the DVD + RW standard. Which means that the software is not a quick " " Delete command, but does it delete itself, as on DVD + RW. Read more on understand.
The big exception to all the above is DVD + RW (DVD + RW). The designers of the format were smart enough to decide that there is not a function to delete this format at all. For a complete delete only the so-called DOW (Discover-Write) and thus reduces the quality of the media. If a complete deletion is in fact required by the user to the application software can still write a neutral picture of the entire surface of the CD with the same effect. And, as with a DVD + RW can have only one lane in a meeting, the modification of the inner circle structures is not required, either. If there is already a track … And then there is already a track .. Why? If you want, then write new content, the old data can be easily overridden. This of course also positively influenced background format and other features, which I will not go now. In other words, there is no clear command that a user application can send.
If will quickly erase a DVD + RW then the application software must be smart enough to just a few neutral data on a file system structures (such as ISO9660 and UDF etc ). And, in fact, that what most applications to delete them quickly if a DVD + RW.
The consequence is that, for a DVD drive, there is still a trace after a quickly delete, so this is not blank media , and if it is a track with a length then, data recovery software, you can read commands and data. And a scan for missing data can be positive earnings results.
Same as DVD-RW, there is a big exception. The reason for this is that at the beginning, not all drive manufacturers understood the philosophy and spirit of the well-thought out " no command delete " principle. So what they did was to ensure that a format command functions much like a delete command, and then they have all the software vendors who are visibly confused, a format that they send command, instead of a blank command. Wrong …
To the best of my knowledge, most providers now have the go " no clear " + RW philosophy correctly and recently developed drives no longer be deleted, even if a format command is sent. The same is true for the software vendors, they saw the light. However … It is difficult to change the world and exceptions persist from there.
So if people ask: " I have a fast deleted, DVD + RW or DVD-RW … It can still be restored ", it is difficult to give a definitive answer, because so much Depends on the type and firmware version, and even the writers, in combination with the software and delete the version of that software.
From experience, quickly erased DVD + RW media, deleted, with a current drive and current software is very often recoverable. Chances for success significantly deteriorated for DVD-RW, because many applications, you can simply delete a command (or format command) to the drive. Quick deleted CD-RW is refundable only in the laboratory or with special tricks that are difficult to explain this here.
Hope sense to you …
Terminology: Delete " " and " Blank " are essentially the same software usually uses the term " Erase " while the official specifications and standards use the term & quot ; Blank " as in Full or Empty Quicklinks Blank.
