Tried to install this on a I7 running on a Asus P6T Se on bios 908.

I enabled AHCI in the bios but the drive was not recognised on boot up. Swapped the power and SATA cable to one that were working still no joy. Swapped them back to the HDD and that booted just fine.

I have also changed the registry to enable AHCI for windows as that was preventing the system from booting up.

Any ideas what's the issue, changed the drive and cannot see anything on it that I could change.

The cables are 110% working
