An old IDE drive got a S.M.A.R.T. error message from BIOS during boot-up. Windows 7 starts out with a message recommending that I back up the drive using Windows Backup and Restore. The drive no longer shows up with a drive letter in Windows 7, but Windows 7 obviously knows it is there, hence the message. But when I hook up an external USB and start Windows Backup and Restore, it only shows me the drive letters C: and D:, the good SATA drives, with no drive letter for the old IDE drive. So, how can I back up the drive so that I can restore it onto a new IDE drive I just bought as a replacement?
