Oops. I just reread that this is now SATA. New versions of hdparm and
smartctl can tell you if the drive is Advanced Format, and if it is,
then I recommend redoing the partition scheme so it's 4K aligned. And
so that it has an MBR gap. The current way to do this is have the 1st
partition start at LBA 2048.
