For hardware diagnostics, you'll need to know who manufactured the hard disk
(Western Digital, Seagate, etc). Then you may be able to get diagnostices
from their site.

Let this forum know if this helps or if you figure out the problem, so
others can benefit.

On each occasion I have run chkdsk and scandsk diagnostics and there are no
problems detected so that's a bit confusing to me. Is there anything else I
should be checking that could be creating the problem - perhaps a faulty
cable or something else. My computer has 2 hard drives - the primary C drive
is the one that is 'failing' and it is mounted 'vertically' on a chasis. The
second drive is mounted 'flat' on the bottom panel.

First, those are not hardware diagnostics. Those are Windows
diagnostics. It is an HP. Computer manufacturer is more responsible
- provided comprehensive hardware diagnostics that give numbers and
detailed messages. Without those numbers and messages, then the few
who can actually answer your question will not post.

Only one 'disk drive computer' controlled both drives. If either
drive is defective, then the one computer will report a failure. Is
the defect in drive two but you keep replacing drive one (because
drive one controls drive two)?

Second reason for failure are completely and always defective power
supply voltages. Completely defective power supply can boot a
computer. The naive then assume the power supply is good. Power
supply causes strange things to happen once every month. Does that
sound like your computer? 'Sound' means nothing. Again, the numbers.
Voltage measurements are the only way to identify or eliminate that as
a reason for a failure.

Heat is not a problem. Your computer must be in love when a room is
100 degrees F. A computer that is failing in a 70 degree room does
not have a heat problem. It has a hardware problem. How to find a
completely defective machine? Operate it even in a 100 degree room.
If it fails, a hardware problem probably exists - another reason why
more responsible computer manufacturers provide comprehensive hardware
diagnostics - to find that failure even when heat makes the failure
easier to find..

Step back. Is your problem with hardware or software? Windows does
little to find hardware failures. Windows works around hardware
failures - does everything possible to ignore those problems. However
Windows also has system (event) logs so that months after a problem
occurs, then a hardware guy can identify the problem. What (exactly
letter by letter) does each failure message in those logs say? Just a
few suggestions that would go after a problem rather than its
symptoms.
