Hi Tony, thanks for the quick reply!

I've not had any other evidence of hard disk problems. I've also not added anything to the player recently - the last change was to put v2.00 final and Hijack on, but I've uploaded since that, before today, and it went fine. I don't have any @EXEC programs at the moment.

I don't think the player rebooted during the upload - it was a single album I'd just bought and ripped, so I was watching it. You know how in Emplode, as each song finishes uploading, the icon in the playlist window changes to show it's done? Well it did that for the first four, but for the last 7 tracks, it spent the right amount of time uploading, but didn't change the icon. Those are the tracks that gave errors.

I've done nothing since the reboot, and I've still got the error window open. What's my best way to either confirm it is a hard disk problem, or rule it out?

Cheers!
