Hard disk lock - secure enough?

Hi

Do anyone on this list have experience of pen-testing hard drive locks?

I've been googling around to gather information of the security implications
of deploying hard disk locks, and the opinions seems to be very scattered.
Could hard drive locks be an alternative to hard disk encryption solutions?

As I've understood you can't break this protection with less effort then
removing the magnetic media from the physical harddrive, or would it be
possible to exchange the eeprom where the password is stored? Is there any
known way to reverse engineer the password or read it from the eeprom? Is
there usually any brute-force protection implemented that rends the hard
disk unusable after a numerous of unsuccessful authentication attempts.

Any input would be welcome.
