"!!! QueryDosDevice failed"

Right, i left my PC on last night cos i was installing winamp before i went out and didnt have time to finish it before i left. Came home this morning to find my PC off, which means my mum's taken it upon herself to switch it off. When i switched it on again i got this "!!! QueryDosDevice failed" error popping up every 20 seconds or so.

I figured that it'd be due to the fact that winamp hadnt been installed properly, so uninstalled it, but it's still doing it even after a reboot.

I've done a google search on it but it doesnt seem to have come up with anything useful.

Does anyone have any sort of idea how i can get it to stop popping up and what it is thats causing it?

Cheers

managed to fix this by uninstalling my raid drivers and installing them again.
