Whilst the drive SHOULD be backwards compatible, this is not always the case. Don;t know if simply changing the cable will make it compatible or speed things up.

Well, currently I have a SATA cable on a SATA II controller. Apparently, the drive is only backwards compatible with SATA II and the SATA cable can't handle the overload.

I dunno. I'll give it a whirl and see what happens, anyway. At the very least, should see a speed increase on the SATA controller after replacing the cable, as it will allow 3Gbps throughput.

When you formatted the SSD, did you use the GUID partition table?
