Files deleted from your USB thumb drive are not removed immediately; the deleted files are still known to be occupying the space although it is not visible in Microsoft Windows. Why is that so? 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.
Who needs this software? If you happened to be sharing your USB flash drive with an IT expert friend and the USB thumb drive used to contain your private files (e.g. homemade video) which were deleted weeks ago, you should definitely try these data remover to avoid any unwanted incident. Also, securely erase all of your laptop’s data on your hard disk before you give it away or sell it. The best way to permanently erase all data and files is to perform a few times this task with a few other software various times.
These free software works on all SSD hard disk, SATA hard drive, USB Thumb Drive, Flash Drive, SD Memory Card, Smartphone removable microSD Card and more. Most of them runs on Microsoft Windows XP, Vista, 7 and 8 (64-bit desktop). Some do runs on Apple Mac OS X and Linux. Remember, almost nothing is guarantee, everything man made can be unmade.

Each “Scrub Type” is a collection of “Scrub Patterns”. The Hard Disk Scrubber offers 6 different scrub patterns in all. Each pattern is a 512K block of bit data. This data is what is used to overwrite the private data that you are permanently destroying.
- Normal – Single Pass using Random Pattern
- Heavy – Three passes, using Zeros, then Ones, then Random
- Super – Five passes, using Zeros, Ones, Checkerboard Beginning with Zero, Checkerboard Beginning with One, then Random

Flash Drive Note: Nearly all modern flash drives use wear leveling to spread write operations out over a device. This interferes with Eraser (and other secure deletion utilities) ability to wipe single files. 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
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.
