The PC interface

SAFE interface for Kidde CO/Smoke alarms

Applies to all: Encryption!

Disk Drive Sanitization

The universal method for securely removing all data from a drive is to encrypt all the data in the first place! Erasing encrypted drives with the "Dumb" method MAY NOT always be complete, however. Encrypted drives need a section of data holding the decryption ...

Dumb but effective: overwrite data (HDD's and some SSD's)

Disk Drive Sanitization

For Spinning disk drives, and SSD's that don't support secure erase/sanitize commands, the only other option is to manually overwrite all the data on the drive. Why this is the least secure method of erasure: HDD's and SSD's self-manage bad sectors/blocks. Whe...

Disk Drive Sanitization

MOST SATA-based SSD's support some type of secure-erase. This is a much faster and more effective method of erasing data than the one as described in Dumb but Effective. Instead of overwriting with pseudorandom data at the OS level, which may leave some bad b...
