I have a Dell laptop that I am trying to fix a starup issue with. I have gotten the laptop back up to the desktop but have found two problems that still remain. I suspect the hard drive is bad and went to Ghost the drive but got an error message that says "Attribute sequence out of order (407)", so I went back into the XP O/S to run a disk check and defrag. The defrag pops up an error message that says "Disk Defragmenter NTFS Module has encountered a problem and needs to close. We are sorry ....." How do I fix this?
