Recommended Posts

I have a small (8.4gb) Samsung hard disk on a second computer. The power supply went poof, sparks an all.
I transfered the hard disk to another computer but it won't spin up, a green led on the board tells me that it's recieving power.
the question does anyone know if it has internal protection like a fuse diode?

The disk was used as a data backup an I would like to recover some important items

Great idea. I've looked on ebay an found two.
now to find a way to have one sent to Spain,
Time to call in some favors from my American friends.

Edit to say:- Just found out that their is a Spanish ebay and PayPay operating here (serves me right for not surfing more often)
sent for the hard disk €15.00

Again, thanks for the idea.

and when he said exact, he meant EXACT. right down the revision of the drive. They may make 5-10 revisions of the same drive in its' lifetime, and sometimes it changes the way it writes to the platters between revisions. Could be great, could be "deadly" to the data on the drive.

I did that the wrong way once. tried the trick with a board that was 3 revs different. never saw the data again.

YMMV
Two wrongs don't make a right, however three lefts DO!

I wonderd about that, an if changing the board lowers or raises the heads all I'm out is the data.

What I dont get is how a fried power supply managed to do so much damage,
must of been one hell of a power surge on the 12v side

I concur with the other posts. Try to obtain a logic board from another drive that is the same revision.

Barring that, your only hope is a data recovery company. They can work miracles, but you'll pay dearly.

BTW - where was your backup? :o

edit to add: sounds like it was the logic voltage or the logic bus (+5VDC) that took the hit - all the 12V does is power the spin motor.

Yep, if you want to try this, you've got to get the revision right. I had this with a harddrive that died, fortunately using the wrong board revision didn't do any further damage.

First I used the board of a spare drive, but that didn't work, different board revision.
Then managed to hunt down a 2nd hand drive with the right revision and I managed to pull all my data from the broken drive. (saved me quite some time restoring backups and redoing video editing...)
I built the board back to the 2nd hand drive and that one is still running today.
Plus I got the broken one replaced under warranty B|
