delete == delete

[der.hans]

moin moin,

talked to a co-worker tonight about a need to wipe a bunch of disks. He
pointed out that there's a hidden feature in newer IDE and SATA drives
that supposedly does a real delete of data for every single block on the
drive.

Are there any Free Software programs that can trigger this type of erase?

Is there a similar type of erase for SCSI?

ciao,
