Can you replace electronics or circuit or fuse on HD?

Here's what happened. I opened the case of one of my PC's to attach a CD
Burner to test it quickly. I shutdown the computer, and then attached the
IDE cable and then the Molex power connector to the Burner. There was a
spark as I was trying to connect the Molex as I had it lined up incorrectly
(it was inserted at an angle kinda) and then I realized that on this PC
after you shut down from within Windows, the power supply would still run
quietly and you had to manually turn it off. (Couldn't figure out how to fix
this).
Well, the 80 Gig Western Digital that was on the adjoining Molex won't spin
now. I tried powering it from several sources and another computer and it
won't spin up.
I'm thinking that the Data is probably fine, but the board, or part of the
board is fried.
Next step? I run a tech service for home users so I'm pretty good at lots of
tech stuff, and have done data recovery with software, but never messed with
any HD physical repair.
Many thanks for any insight.

Just unplug the power cord.

You can swap the logic card from an otherwise identical
drive, but that doesnt always work and I have seen
reports that it doesnt work with WD drives of that
vintage, even with a pair of brand new identical drives.

Pro recovery will work, but isnt cheap.

Corse if you had the data backed up properly, you
could just buy a new drive and restore the backup.

Well, board swap is tricky. Sometimes it works, sometimes it does not.
And you may need to try different boards. In addition this could have
also damaged the pre-amplifier inside the disk housing. Board swap
will not help.

If the data is critical, I would advise you to seek professional
help. Not necessarily for the work itself, but one thing well
equipet data-recovery outfits have is spare parts for a lot of
different disks and knowledge, what works with what.

If the data is worth little, best just throw the disk away.

Suggest that you have a non-standard or faulty PSU. After power
down from Windows the PSU should only provide output on the +5VSB
supply line; sparking from the Molex 5v and 12v supplies should not
be possible from a standard-compliant and correctly functioning ATX
PSU.

Hi O2befree (what a name?).
What would You expect after gotting a spark?
This identifies an electrical problem!
HW would never recover by itself. You've a problem.
