Memtest86, then HD won't boot.

Looks like simple drive go splort. Maxtor diagnostic shows, reset pass, recal fail, and tells me to call customer support with error code UK. Lots of warranty left, and I already popped another Maxtor, a 18 GB, into the system and its formatted and being restored right now. I'm chalking it up to another notch for the wish I done a backup recently, but I was planning on a full restore soon to tackle a no sound problem. I wish the people that design drive bays and the people who design 3.5" to 5.25" adapters could meet each other, and perhaps later be fed to rats, but overall not too painfull. With the recovery just started, and 4 hours til I want to leave for TRW hamfest, sleep isn't looking too likely. Thanks all for your help, and I dispell any doubt cast on Memtest86. (no plans to use it though either. ;)
