Well, when you delete a file, Windows marked that particular sector in your hard disk as free in the registry, the content is removed when a new data is written onto the previous ‘free’ space, therefore if no new data is written, and it is possible to retrieve the ‘deleted’ data.

Flash Drive Note: Nearly all modern flash drives use wear leveling to spread write operations out over a device.

Wiping an entire drive or erasing a file and then wiping free space may be a little more secure but still not delete all data, though it will put additional wear on your drive.

↓ 11 – Microsoft SDelete | Files | Windows

microsoft sdelete Freeware To Securely Erase All Data From HDD Hard Drive

One feature of Windows NT/2000’s (Win2K) C2-compliance is that it implements object reuse protection. This means that when an application allocates file space or virtual memory it is unable to view data that was previously stored in the resources Windows NT/2K allocates for it. Windows NT zero-fills memory and zeroes the sectors on disk where a file is placed before it presents either type of resource to an application. However, object reuse does not dictate that the space that a file occupies before it is deleted be zeroed. This is because Windows NT/2K is designed with the assumption that the operating system controls access to system resources. However, when the operating system is not active it is possible to use raw disk editors and recovery tools to view and recover data that the operating system has deallocated. Even when you encrypt files with Win2K’s Encrypting File System (EFS), a file’s original unencrypted file data is left on the disk after a new encrypted version of the file is created.

The only way to ensure that deleted files, as well as files that you encrypt with EFS, are safe from recovery is to use a secure delete application. Secure delete applications overwrite a deleted file’s on-disk data using techiques that are shown to make disk data unrecoverable, even using recovery technology that can read patterns in magnetic media that reveal weakly deleted files. SDelete (Secure Delete) is such an application. You can use SDelete both to securely delete existing files, as well as to securely erase any file data that exists in the unallocated portions of a disk (including files that you have already deleted or encrypted). SDelete implements the Department of Defense clearing and sanitizing standard DOD 5220.22-M, to give you confidence that once deleted with SDelete, your file data is gone forever. Note that SDelete securely deletes file data, but not file names located in free disk space.

    “Everything man made can be unmade” – I like that statement. Useful information presented here. Believe it or not I was not aware the fact that USB drives still contained recoverable data after deletion of those.

    I have tried several of these to wipe the free space on an external hard drive (e.g. Eraser, Disk Redactor, Moo0 Anti-Recovery, MS cipher command) and all of them leave traces of files which seem to be impossible to erase. Anyone know of any program which completely deletes all traces of all files, short of reformatting the complete disk?
