Any ideas on this anyone? A SATA 2.5" drive has a corrupted OS on it and I want to format it and then reinstall a fresh copy of Windows. The drive is detected by the BIOS but does not show up as an available drive in the install routine (no drives found). I If I remove the drive and connect it as a SATA drive to a desktop (so I can format it that way), it again shows up on the BIOS but is not available as a drive in Windows Explorer. This drive has been pre-repaired by PCWorld - I wonder if they did anything odd to it?
