I no longer believe that software will fulfill the role of cleaning up. I no longer throw hard disks in the trash. I recommend destroying them with a good sledge hammer, the cost of the sledge hammer is well worth the loss of data that can be obtained using good forensic software.

See “Remembrance of Data Passed: A Study of Disk Sanitization Practices” IEEE Security & Privacy

http://www.simson.net/clips/academic/2003.IEEE.DiskDriveForensics.pdf

Which states on page 19 on the right side…

The most common techniques for properly sanitizing

hard drives include

ï Physically destroying the drive, rendering it unusable

ï Degaussing the drive to randomize the magnetic domainsómost likely rendering the drive unusable in the process

ï Overwriting the driveís data so that it cannot be recovered

Sanitizing is complicated by social norms.

Clearly, the best way to assure that a driveís information is protected is to physically destroy the drive.
