Something to consider. You're drive may not support AHTI. In which
case it's "disappearing" was a 100% guarantee if AHTI was enabled.
Also, you might need to run this drive in IDE legacy mode.

By coincidence, when building a machine for a friend yesterday, his
drive (a WD 250gb SATA) proved to be (a) a SATA, not SATA2 drive, and
(b) disappeared when AHTI was activated. Setting the bios back to
non-AHTI made it reappear. We were able to run in SATA native rather
than IDE legacy mode.

You'll want to check both these issues in your bios, before replacing
data and/or power cables.
