Hard drive circuit board

Specs: xp, 633 512
Hello. I have a hard drive that was in an external casing but the circuit board on the hard drive was burned out because of a power surge. Is it possible to just take a board from any hard drive and replace it or do you think that it is company specific? the acutal hard drive wasnt damaged so i know if i can get a good controller that it would be ok as i do not wish to fork out big money for data recovery. So what are your thoughts, experiences, etc?

I am sure it is unique.

With all the online places that offer second hand junk, you ought to find an exact drive that you could try to recover your data. I warn you that you run the risk of further data loss with this action too. Your best bet is to use a company if the data is important.

I read it wrong and answer it wrong too. So get off my case you peanut.

You will need the exact model of drive as you have now, right down to the revision number. The circuit board contains the logic the does the disk geometry translation. Get that wrong and the disk will be unreadable. There are areas on a hard disk that are only accessible by the hard disk controller card. This is likely to be different for each hard disk, even within manufactures.

However, replacing the circuit board on a hard drive is not a trivial task. Don't open the case that contains the platters. Once you do that you can more or less write the disk off. It has to be opened in a clean room to prevent dust contamination.

Exactly the same. An 80GB will have different geometry information stored in ROM than a 40 GB so no, it wont work.

make sure you have the identical hard disk drive with the identical model, part number and MLC or DCM plus more importantly the firmaware.

You need the logic from another HD. Use to do it all the time at my old job. Just swap the board out with the same model HD board. Firmware revision really should not matter. So long as the two drives are the same model the boards will work in either.

I cannot believe it. Post 5 comment came from someone connected with a recovery lab and Post 6 says it's not the way it should be :-)

The firmware version is important. Different firmware may work, but there is a chance it wont.

As stated earlier, the firmware has access to information on the disk that is not visible to the user, it is put there by the manufactures during the real low level format process. If a later firmware revision changed the location and format of this information, which is highly probable, then it wont work.
