Weird "Would you like to format it now?" problem... VIA motherboard perhaps?

[MIDIman]

OK - I posted earlier about having a problem with my mediacard reader on my Dell 2405, but now it appears to be related to ANY "removable disk" I plug in, ANYwhere on my computer. I just tried plugging in my Archos MP3 player and it has the same problem. My Crucial thumbdrive as well. Basically, the "device" is detected and gets a drive letter, but when clicking on it, I get "The disk in drive X is not formatted. Do you want to format it now?"

I've tried multiple different USB connection on this computer (front, back, etc). I have an ASRock 775Dual-VSTA based system, WinXP SP2. Just updated to the latest BIOS version.

All of the devices I've plugged in have been verified working fine on other devices, computers, etc.

Any thoughts? Super annoying...
