Linux:

First check the drive (see if erase operations are supported):

# hdparm -I /dev/X 

# hdparm --user-master u --security-set-pass Password /dev/X

# time hdparm --user-master u --security-erase Password /dev/X

or (if supported):

# time hdparm --user-master u --security-erase-enhanched Passwrd /dev/X

Works also for HDD’s.
