Privacy and Security Risks
People store important and often very sensitive information on their computer drives, copy it for safe keeping on backup disks or exchange it on floppies, ZIP drives or other types of removable media.
When you give your coworker or friend a file or a program on a disk (floppy, ZIP, Jaz, or any other type of disk), you may actually give him access to the information that the disk used to contain. You may have used that disk to store backup copies of your financial records or business plans, or you may have used it to transfer your private files or e-mail messages from your office computer to your home PC. The bad news is that large parts of that information may still be available on the disk.
But how is this possible, considering the fact that you have formatted the drive? This should have removed all those files and data that used to be stored there in the past!
Actually, when Windows formats a disk, it does NOT remove all data and files from disk. Such a process would take a longer time, so in order to improve performance, Windows only marks the disk as being free and ready to store new data. The old files and data remain on disk and they may be replaced with new data when new files are copied to disk. A complete replacement of the old files and data may actually never take place - unless you copy the same amount of new data over the old data. And even if the old data was completely replaced, a lot of recovery tools may still recover it from underneath the new data.
Old data from a disk may be recovered with any type of recovery tools, many of them freely available and very easy to use. Hundreds of unerase and unformat programs and disk editors are available and can be used by anyone. More advanced, but not very expensive, hardware recovery tools are also available. These tools are able to recover data that was overwritten and replaced with other files.
The same security problems are encountered with your hard disk. Let's say you used to have a D drive on your office computer, that used to contain your personal files, ideas or plans, but the computer became insecure and you decided to move that information on your home computer or laptop and remove it from the office computer by formatting the D drive. Anyone with access to your office computer can recover "your deleted" data from the D drive using easy to use recovery tools.
وسلامتكم
