Mine is an early issue of XP. SP1 is installed separately. SP2 was downloaded. No bios conflict. So once you install XP and then add SP1 you have to go back and use repair to get the OS to see the drive or does it just appear? Or did you use Western Digital tools to format the full C drive and then perform the install? BTW: There is no FAT 32 issue here. Q
