I got 2 of the 1.5tb version of these drives, and the sector size
is this way too, I think its pretty dumb. Apparently ibm
compatible bioses can't handle any sector size but 512 bytes, so
the firmware will always say its 512 even though its 4096
internally, and you are just expected to make the partitions
aligned on a 4096 byte boundary, which seems to be painful and
annoying to do in fdisk or parted. Parted also likes to use
metric instead of binary prefixes which doesn't help at all. I
was trying to install centos 5.4 on the drives when I got them
about 6 months ago, and haven't played with them much lately.
Maybe parted or fdisk have gotten better since then about setting
the alignment?
