Recently had some problems and reformatted my primary hard drive. I worked out a system and made a complete back up of my SATA primary hard drive to my secondary IDE hard drive which used to be an external. The secondary drive I also reformatted to NTFS from FAT. Everything worked fine for a while including my networking to other computers and my xbox 360. The other day in the middle of a video the drive stopped working and disappeared. After a few reboots my drive showed back up. I can't seem to do anything as far as reformatting, deleting files, or copying files to my primary hard drive. I keep getting various delayed write failed messages. Can anyone help me out with this?
