I had it tried on my brothers desktop it never showed up on bios or disk manager but today i set it up as an external and it works is it the cable messing it up?i presume this 1tb is an internal drive not external? if internal, can you try it on another computer whether desktop or laptop, doesn't matter, to see if still have that issue as the drive might be a DOA.
No cluebut your brother's computer uses 2 cables for sata drives, power & data so why didn't his computer not see the drive?
