Short circuited hard drive?

July 28, 2010 at 11:19:43
Specs: Windows Vista Ultimate
Samsung 500GB SATAII

About 6 months ago during a rebuild i reconnected the above mentioned hard drive and may not have connected the SATA cables correctly and now it doesn't work when i plug it in to my computer it takes ages to load then doesn't even recognise it not even within BIOS or any third party recovery software. I desperately need the files on it and want to know if there's anyway i can get it to work... Once windows can read it i can do the recovery myself if it's corrupted normally i'd just try a straight format then use a data recovery software but as i mentioned even third party software cant see it.
Any help would be greatly appreciated :)

how could you connect the cables wrong? Describe what you did and what the current problem is.

I think i didn't push the data cable (or the power cable whichever would cause this) all the way in til it clicked the hard drive spins and clearly windows is trying to read it hence the severe lag (2 minutes without the hard drive connected and 15 with and a further 10 til explorer loads) so it's either corrupted or fried i cant tell which.

Some motherboards with SATA I controllers have problems configuring SATA II hard drives. Most, but not all, SATA II hard drives have a throttling jumper on the back of the drive that forces the drive to run at SATA I speeds. That may be your issue. Set the jumper for SATA I.

SATA hard drives are hot swappable so connecting the data cable under power shouldn't have a negative affect. Connecting the power cable could, but then the drive would not be identified by the BIOS. This could be you problem. If so, there isn't much hope. Have you tried using a hard drive fitness test from the manufacturer? You boot to a disk with the fitness test on it to run. If that can't see the drive then something is fried on the drive. Possibly the PCB (printed Circuit Board). It is possible to get a matching PCB off a working drive and change it. The PCB must match exactly. Model of drive alone is not enough. Firmware and other factors matter. Professional recovery may be in order.

Have you considered the issue may be the SATA controller or data cable? Verify the controller is enabled in the BIOS and the controller is functional. Try a working cable.
