I had to use the SeaGate SeaTools for DOS tool to erase Track o and then do a wipe of the drive, but that solved my problem.
This Inspiron 570 has a 1 TB Seagate Hard Disk. It is detected by the BIOS, it is detected by and passes PSA Diagnostics.  The BIOS is set for AHCI.  I'm trying to reload the OS which is Windows 7 Home Premium x64 SP1 but Windows doesn't detect the drive at all. Thoughts or ideas? Thanks,Daniel
