Mmmm. I've had hard drives freeze up. Some could be brought to life
with CPR (tap them, not too gently or too hard, with the handle of a
screwdriver). One or two never came back to life.
Admittedly, these were FM and MFM drives of about 20 to 40 MB each
(yes, megabytes). Perhaps not the latest technology today...
However, there are other failure modes available for an enterprising
hard drive.
