I got hold of an old Dell E6410 laptop which had in it a hardware FDE Seagate Momentus 7200 FDE2 hard drive, and I want to install Linux on this machine.
When I boot from a USB drive running Linux live, the attached disk shows only one partition - the MBR, of size 128 MB. The laptop boots, there's no BIOS level password set for the harddisk. After POST, a disk encryption prompt pointing to "wave.com" (For Wave Systems Disk Encryption) comes up and after keying in the right username and password, the disk is unlocked and it boots to Win 7 which is installed. Now I intend to knock off Windows and run Linux. But once Linux boots, there's no disk to clean/unlock at all. hdparm
seems to fails in unlocking the drive as it reports that it is already unlocked. I searched on hddgurus, Dell & Seagate and various other forums to no avail, and wave apparently shut down and they do not have any support anymore.

hdparm --security-unlock
or --security-disable
doesn't seem to work since the disk is showing only one partition and that doesn't have anything set.
hdparm forums mentioned that Master password revision code = 65534
implies the master password (which as given at https://www.seagate.com/staticfiles/support/disc/manuals/notebook/momentus/FDE.2ProdManual.pdf, "The ATA master password is set to the Security ID (SID)." ) is available. But since none of the tools (hdparm, or even the Embassy Security Centre TDM) are usable to get the drive to disable hardware based FDE.
Any hints on how best to proceed? Would I be better off throwing the disk away and using a new one?
It's a totally unused 250 GB 7.2K rpm drive and throwing it away seems very wasteful.
