What does "locking" the drive really do?
Causes the drive to misreport it's actual capacity - it can still access the first bit of the drive, but it'll refuse to access the rest of it until it's unlocked. Older drive firmware had bugs that would cause stuff like switching to LBA mode to unlock the drive (hence why dlgchk used to work) inadvertently.
qunlock unlocks the drive properly - it gives back the proper challenge/responses, and rewrites the locks to eliminate the locking.
This was done most likely to prevent people from trying to fraudulently get a free hard drive from TiVo - buy a TiVo, remove hard drive, return TiVo as "nonfunctional" and get a free hard drive. (30 GB hard drives were popular to rip off...). I wonder if ReplayTV or UTV have the same issues...
