I've kinda given up for the moment. I finally figured out the 137GB limit and created a partition much smaller than that. The driver *seems* to work, but when I do md5sums on the files I copy to the disk, I get random results, i.e. never the same thing twice on the same file once RAM cache is cleared. The disk drive itself works just fine on a different machine using sata_nv. Maybe it's something specific to the 1622TA2 card I have. I dunno. I have another SATA drive coming that's only 80GB. I'll put that one on this controller when it comes in and see if things change.
