iPod Classic keeps restarting. Already tried several solutions I can find.

Thanks so much for your reply.

In diagnostic mode the results were:

Retracts: 19

Reallocs: 0

Pending Sectors: 0

PowerOn Hours: 1049

Start/Stops: 36063

Temp: Current 24c

Temp: Min 77c

Temp: Max 249c

This looks like it's not a hard drive failure? the max temp and start/stops look really high - not sure if they might be the problem?

I'm going to try reformatting and the break-up of transfers - will let you know how it goes!

Is there a way to fix corrupted CMOS data (if that's what's causing the problem)?

I tried reformatting and breaking up data transfers as suggested. Reformat went okay. As soon as the first few files had been synced, iTunes stopped recognising the iPod (still showing as connected on screen and in My Computer). Tried playing the files synced and after a few minutes the same thing happened - iPod just froze and had to be reset.

Any idea what I could try next?

It seems to have done the trick! Found a file using Spybot and after deleting that, it worked fine for a few days. It froze again yesterday, but as soon as I scanned it again and found the same file (named something like Volume Limit) with Spybot it's back to working normally. Thanks so much for your help!

In case it helps someone else, this is the file that seems to be causing the problem:

Ah. I misunderstood the post. I had excluded the iPod before and it was making no difference. I've since tried disabling antivirus and reformatting but it's still resetting itself.
