I recently cleaned up an older pc running Windows XP and upgraded it to SP3. I have a Sandisk U3 USB drive that wouldnt work. The PC recognizes the drive but when you try to open it it says that there is nothing on it and has zero free space. I reformatted the USB drive (FAT32) on a different PC and it still doesnt work on this PC. Same display - no files on it yet zero free space. I tried putting files on it from another PC and it works fine on other PCs. I tried booting the PC in safe mode and the USB drive works fine there and I can see the files I put on it. I tried deleting the drivers and that didnt work except in safe mode. Any suggestions ?

Thanks

Finally Resolved !!

It turns out that the HP 3390 USB printer kills all other usb ports. Dont yet know why, but when I unplug the printer all usb ports and drives work fine.

Thanks for your help !

That's very strange. Check the HP website for an updated driver.
