Where can i buy a seagate external drive circuit board to replace one I "fried" by overvaulting my current one?

It is hard to buy replacement for the same enclosure, but there are many USB2.0/3.0 enclosures available on the market for 2.5 and 3.5 inch drives.
Make sure read reviews for issues and performance on those enclosures.

BUY A HDD ENCLOSURE (http://www.tigerdirect.com/applications/category/category_tlc.asp?CatId=2777&name=Hard%20Drive%20Enclosures)

I have the same problem like yours right now. The on-board circuit of my Seagate Barracuda burned and I'm planning to buy new Seagate Barracuda with the same specifications, same model.. I will try to disassemble the circuit of the new one and connect it to the old hard drive to take a chance if it will work and retrieve my files. If it doesnt work, at least I try and I still have a new hard dist to store my new files.. If you want to do the same, you must be careful in handling the circuit board. It is very sensitive and can be damaged with just touching the components.. I recommend you to discharge static electricity of your hands by touching anything that is made of steel.. The steel will discharge static electricity, but still, to make sure you wont damage the circuit, just touch the circuit board on its sides.. Never touch any components, it will damage your circuit board.

You will need to get another circuit board from another Seagate Barracuda 7200.7 200GB Hard drive. Either ask your local computer shop or check local ads for sale. Like Gumtree or Ebay or the like.
A hard drive recovery centre may have this particular circuit board as they will use it to transfer your information from your current hard drive to a new hard drive. This may be another option available to you.

Take care!

Ideally you should replace it with an identical one but any other Seagate 1 TB disk will do.

Just pointing that out.

From my own small piece of advice, I would replace the circuit board with one from another Seagate 7200.9 Barracuda Plus 120GB harddrive. Buy a good used one.

This way you can install the circuit board on the one you want to retrieve data from, then reinstall it back on the one you bought, after you have retrieved your data, and have a working Harddrive.

Buying just that circuit board? Mmmm, no.

Just from a quick search,

Information on Harddrives,

Do I know if the damage has gone further than just the circuit board? No, I do not.
Therefore it is a decision only you can make if it is worth the money spent.
There are also professional data recovery services. ($$$$$)

You need an expert to do that. The expert must have the exact same board to swap with the burnt board. If the power did not affect the disk, you may recover the data on the disk.

Hello

OK, you need to let me know if the drive spins up, you should be able to hear it. Also, you need to have a listen if the drive makes a clicking noise.

Please be so kind tom let me know.

If the drive makes a clicking noise the drive is done, you will need to take it to a recovery institution to recover the data.

If the drive does not spin up, the circuit board or the power cable might be broken.

Hope this can be of help.

Kind regards
