Re: can I mark sectors as bad?
Check the to see how hot the drive is getting. If it burns your
fingers (or your friend's fingers), it's quite possible that the drive
is seriously overheating. This can cause an assortment of bad things
to happen. It's possible that the bearings seize up as they
expand. The armature could be going out of alignment and confusing the
drive logic. CMOS chips have a tendency to glitch and eventually stop
working at high temperatures. Or, the drive could be powering down to
save itself from being cooked.
Check the ventilation in the system and the ambient temperature of the
room. Just use your judgment - if it's an elderly drive, the operating
specifications are probably optimistic at this point. If you cobbled
the system together in a hurry, you might have some airflow problems
with ribbon cables.
If you're lucky, that will fix (or at least assuage) the problem. You
should get a new drive anyway, though. I keep a pile of 3 GB IDE hard
drives around just in case - I'm sure you could obtain one easily
