I recently received two hhds from a friend that had his master hhd crash on him. He hooked up a 20 gb quanta bigfoot hhd with XP home loaded (same os as the problem hhd) and transferred all his data to the big foot.I tried to load xp pro on the problem drive via my ghost image back up only to get the invalid drive specification message booting to a win 98 boot disk. i have Now made 3 boot disk and cannot access any drives but a: and b: in dos .I cannot even run fdisk. Why cant i fdisk or format this drive?
