What is Low Level Format for anyway?
The older HDToolBox that had this feature is complete crap for SCSI drives anyway, it doesn't have an option to select Asynchronous/Synchronous transfer modes.
SCSI users should use Phase5's SCSIConfig v1.27.
Bare in mind when you throw an old hard disk out that someone could indeed fix it and recover all your data. So if you have something sensitive on there it is probably best to physically destroy the drive.
