Whilst trying to transfer data from a Seagate Barracuda 250GB 7200.9 Ser:4ND2DEV7 with a USB converter I stupidly got the IDE power supply connector around the wrong way (as hard as this might seem to do ) pushing it into the receiving connector of the adaptor. This smoked one of the components on the HDD circuit board. I'm hoping it is a protection cct of some kind and that replacing the obviously damaged component will fix the issue. Can anyone help me in identifying this component (see image) When I plug the hard drive in now with the adapter around the correct way it still smokes and the drive dosn't spool up.
Many thanks

Oh in the wider shot the component is the one at the top of the picture close to the SATA connecter second in from the left (on a bit of an angle)

Remove it. If you were lucky enough the damage was limited to the tvs. If not, we'll see.

I gotta say that this is one nice macro shot!

You may inspire me to do an art project with my macro lens and my graveyard of drives.

Good luck with the drive.

Many thanks for your help guys!!
I can't wait to see some of the art Wiseleo I've got a few others I could add to that....
In further delving on the forum a found this thread really helpful explaining what TVS diodes are and how they work.

I'll let you know how I get on.

Many many thanks guys. I did as you said BlackST and just removed the diode and off it went. I'm transferring data as I type this!
and for you wiseleo...here is what remains of the offender....
again many thanks guys, much appreciated!

To complete work, replace the tvs - it's a protection device. And use the drive again as secondary or for non critical storage.
