Permanently & Securely Erase All Data From Hard Disk or USB Storage
An overwhelming majority of people, businesses and organizations do not understand the importance of security in digital data storage.
The average hard drive sees thousands of files written to it, many of which contain sensitive information.
Over the course of a hard drives lifetime, the likelihood for recoverable remnants of sensitive information left on a hard drive at its end of life is very high.
And, data breaches are not limited to hard drives! Even formatted USB drives will have files able to be recovered.
KillDisk Destroys Data!
With KillDisk, all data on your hard drive or removable device can be totally erased, and certified safe, without the possibility of future recovery.
After using KillDisk, disposal, recycling, selling or donating your storage device can be done with peace of mind.

Advanced Data Recovery Systems
Advances in data recovery have been made such that data can be reclaimed in many cases from hard drives that have been wiped and disassembled. Security agencies use advanced applications to find cybercrime related evidence.
Also there are established industrial spy agencies adopting sophisticated channel coding techniques such as PRML (Partial Response Maximum Likelihood), a technique used to reconstruct the data on magnetic disks.
Other methods include the use of magnetic force microscopy and recovery of data based on patterns in erase bands.
Although sophisticated data recovery systems are usually only available at a high price, data can also be restored with the help of off-the-shelf data recovery utilities making your erased confidential data quite accessible.
Erasing Confidential Data
Modern methods of data encryption can deter unwanted network attackers from extracting sensitive data from stored database files.
But, attackers who want to retrieve confidential data are becoming more resourceful by looking into places where data might be stored temporarily.
A hard drive on a local network node/machine, for example, can be a prime target for such a search.
One avenue of attack is the recovery of data from residual data on a discarded hard disk drive.
When deleting confidential data from hard drives, removable or USB devices, it is important to extract and erase all traces of the data so that recovery is not possible.
Most guidelines around disposing of confidential magnetic data do not take into account the depth of today’s recording densities, nor the methods used by the operating system when removing data.
For example, the Windows DELETE command merely changes the file name so that the operating system will not look for the file. The situation with NTFS is similar.
Removal of confidential personal information or company trade secrets in the past might have used the FORMAT command or the DOS FDISK command.
Using these procedures give users a misplaced sense of confidence that their data has been completely removed.
When using the FORMAT command, Windows displays this message:
WARNING: Formatting will erase ALL data on this disk.
IT DOESN’T! The FORMAT utility only creates new FAT and ROOT tables. It leaves all previous data on the disk untouched. An image of the replaced FAT and ROOT tables are stored, so that the UNFORMAT command can be used to restore them!
And, FDISK merely cleans the Partition Table (located in the drive’s first sector) and does not touch anything else.
Moreover, most hard disks contain hidden zones (disk areas that cannot be accessed and addressed on a logical access level).
KillDisk is able to detect, reset and remove these zones, cleaning up the information inside.
Wiping Confidential Data
You may have confidential data on your hard drive in spaces where data may have been stored temporarily.
You may also have deleted files using the Windows Recycle Bin and then emptying it.
While you are still using your local hard drive, there may be confidential information available in these unoccupied spaces.
Wiping the logical drive’s deleted data does not delete existing files and folders.
It processes all unoccupied drive space so that recovery of previously deleted files becomes impossible.
Installed applications and existing data are not touched by this process.
When you wipe unoccupied drive space, the process needs to be run from a bootable CD/DVD operating system.
The wipe or erase process uses an operating system that is outside the local hard drive and is not impeded by the Windows system caching.
This means that deleted Windows system records can be wiped clean.
Wiping drive space can take a long time, but ensures the security and safety of your deleted data and free from illegal use.
KillDisk wipes unused data residue from file slack space, unused sectors, and unused space in MFT records or directory records.
