video iPod logic board replacement/formatting issues

[BenP]

I have a 5th gen 80GB iPod video, on which I recently replaced the logic board. The audio circuit on my old logic board had gone bad. The hardware work went just fine, I didn't have any trouble getting everything put back together, and the logic board appears to be working fine (click wheel, hold switch, battery, etc.). My problem is now with Windows having access to the disk. The iPod starts up and gives the white screen ("connect to computer and use iTunes to restore"), but neither iTunes nor Windows can do anything with it. Windows recognizes it as a USB mass storage device, but after five minutes of trying to access it it fails every time to format it or get volume details.

I have already tried:

1. double- and triple- and quadruple-checking the hard drive ribbon on the logic board - it's connected fine. If I take it all the way out, the iPod just gives a sad face, so I know it's at least being recognized.

2. Built-in iPod diagnostics (select button + previous button). Everything passes tests, the hard drive is recognized fine at the proper size and everything.

3. three different computers - Vista, XP, and Linux. None of them can read the hard disk, Linux doesn't even recognize the USB connection.

4. resetting the iPod, restarting the computers, putting the iPod into disk mode, and all the other little things I've read in FAQs and help documents. None of it has affected anything.



If anyone has experience with this, especially with replaced logic boards, I would greatly appreciate any help. The hard drive spins up fine and I don't think it's a hard drive failure. It's probably something simple that I'm overlooking (I hope).

Thanks!

Any ideas? I realize this is kind of a technical question, but I'm sure some people around here have replaced logic boards and maybe had similar issues . . . thanks for any help.
