Hello all,
I see a lot of great advice regarding a failed HDD. I have a samsung laptop hdd that crashed. I pulled out the HDD and tried a crappy adapter to backup my hdd to another pc and plugged it in upside down. This caused not smoke but a buring smell. I see a lot of advice regarding a burned diode. I tried this and still my HDD would not spin or powerup. It is quite possible I snipped the diode incorrectly. So if i were to get a used or another hdd with the same specs and replace the motherboard just to power up the hdd and backup all my files. Would this work? What exact soec should i look for? PLEASE PLEASE ANY advice would be greatly appreciated. Is there a way to add some pictures to hopefully clarify any questions?
THANK YOU

The middle component of the three-in-a-row is the 5V TVS diode. That should be removed.

The first component is an inductor. Just replace it with a wire link, or flow a blob of solder over it. If you have a multimeter, then check the board for short circuits. If all is OK, then power up the board on its own. If there is no obvious problem, then try the board on the drive.

First step, exact model of the hard drive. Should be a model number on the drive label and a board revision number on the printed circuit board as well.

With any luck, all you need to do is replace the board, however, since you say the drive was having issues before this, your data may already be partially or completely unrecoverable.

Unless you have some specific data you need, or just want to see if you can make it work again. It is probably more time effective to do a fresh install.

There is a saying: If you don't have your files in 3 places, then you didn't really want them anyways.

A burning smell is a very bad sign. Back in the day you use to be able to swap circuit boards out on HDDs and have them work OK, but I don't think that trick works any more. However, if the drive was smoking then it probably means that it is a board issue and the mechanics on the drive may be OK. The trick is to make sure that you are getting the same model and version of the drive that you currently have because even a minor revision difference can mess this all up. If you can find one then try swapping the boards and see what happens, and if it spins up properly then you may be able to run some recovery software to read what is on the platters and rebuild the tables and get things back... but that is a wing on a prayer on the smoke of a chance, so it is not likely worth it unless you have some really important information on there.

In the future you should keep your files in at least 3 locations:
1) a local drive where you use them
2) a local backup in the form of a NAS, or external HDD/flash drive, burned CDs/DVDs, or another computer in the home
3) an off-site backup like some form of cloud storage, or my parents and I are in the habit of mailing large flash drives back and forth with our files on them every year so that if their home burns down then I can send them their files up to that point (or vice versa).

THANK YOU for a quick reply
SAMSUNG HM501 500GB 5400RPM
I am trying to recover any data from this HD. i want to try to witch out the board to see if it will power up to recover my data. If this does not work, then i will decide if i want to take it to a recovery tech. Which is another question. I know this is a costly task to recover data, any suggestion on a site, store place/
thanks again
THANK YOU

The only one I am particularly familiar with is Seagate Recovery. Not sure if they work on non-seagate drives, but I had to refer a client to them once. I never heard the end price, but they were very happy with the service and the speed at which it was provided. Pretty sure they paid through the nose for it though, but as it had tax records for their business it was worth every penny.

The model number is incomplete.

Is this your board?

If so, then a board swap and firmware transfer should cost no more than US$50:

That said, which component(s) did you remove? Note that there is a fuse-like component in series with the diode. You may still be able to get away with a zero-cost DIY repair if you are lucky.
