Yes, it should. I believe that the basic problem that you are having is
that mkfs is thinking that the disk is twice as large as it really is (or at
least this is my guess at the moment). The size originates from the
READ_CAPACITY command, of course - you might want to recheck to make sure
you are not returning the number of 512 byte sectors and reporting a
sectorsize of 1024 bytes.
What kernel version are you using?
