I purchased a Maxtor 3200 Personal Storage 320GB Hard Drive at Christmas 2006. It has functioned perfectly until I went on holiday two weeks ago and accidentally plugged a laptop power suppy cable into the HD as opposed to the HD power cable. The laptop power supply is 19V and the HD power supply is 12V.

Following this, the drive stopped spinning up and the light on the front blinked rapidly.

When I got home, I put the drive into my PC internally and connected it up. However, when I pressed power, the system cut instantly. However, when the drive was unplugged, it worked fine.

Yesterday, I purchased another of the same drives and switched the logic board and the USB-type board that sits between the USB interface and the actual drive onto the original drive. The firmware version stated on the new drive is the same as the original drive.

The drive now powers up and spins up, but when plugged into my laptop in the external casing, via USB, it tried to find new hardware (it is Plug and Play), came up with "A problem occured during installation...may to work properly" and in Troubleshooter says Code 10 error. Device cannot start.

I have tried plugging it externally into my PC and it recognised it as a Maxtor 3200 Personal Storage, then a Mass Storage Device, but hasn't said anything else for a long time, and it appears not to be recognised.

Apologies for the long story, but is there anything you guys can suggest doing to get it to work?

The firmware version on the two hard disks is the same, is there anything else that would matter? The drive has worked on both my laptop and PC previously, but does not require drivers, so it can't be that which needs updating.

Basically, i'm stuck.

Sounds like you really fried it mate.

If you have changed the board and it still doesn't work it's probably something more serious.

Whether it's fixable at all is doubtful.

I understand how I might have fried the boards, but now I have changed it onto the new logic board and USB-board, it spins up again like it should, and the PC recognises it but doesn't quite...if you know what I mean.

I just wondered if anything other than the firmware is important when switching logic boards.

I've get to try putting the now "operating" drive stright into my tower thus removing the need for the USB interface.

I'd recommend trying it without the USB interface or on another machine via USB to confirm whether or not the drive is ok.

Let us know how you get on. :)

I have tried it on my laptop and my PC via USB already. Worked on neither. The laptop actually told me a "Problem had ocurred during installation..." and the PC didn't, but it appeared in My Computer in neither.

I will put it in the tower later on and let you know.
