Hi there Urthwhyte,
What is the SATA mode of your system?(you can check that out in BIOS) Is it set to AHCI?
Apart from that, it would be nice if you just attach the drive to another system and see whether it is properly recognized. In case it is, you can do the following:
- Update your SATA drivers.
- Update BIOS in case the issue persists.
Let me know how this goes,
