IBM has offloaded on Hitachi. They haven't locked up their software and have unlocked IBM's Drive Fitness Test (DFT) it's at version 3.50. I've tried it on toshibas that used to be a no go.
Hitachis feature tool lets you access any drive supported features.
DFT is the one that will wipe a password protected Think pad drive.
Good hunting!
