I got a blue screen on my dell laptop and since I had all of my data backed up, I decided to format and reinstall. I got an error during the reinstall of XP that stated that the battery could not be reinstalled so I decided to run a checkdisk on it. It goes through the first three passes without a problem, but then it gets to the 4th pass and it stalls at 50%. I did a fixboot and a fixmbr and they both said that they completed successfully. I have never seen this happen before. What is going on? How can I get the checkdisk to complete?
