I read in comp.periphs.scsi that one has to have a special
equipment to perform a LLF with any sector size different
from 512 bytes.
FWIW, my drives came formatted with 520 bytes sector size
and I had to reformat the drive to make it useful (don't know when
Linux will support anything different from 512 ?)

David Miller, the author of "scu" utility, mailed me an example
where he made 4096 byte sector size on his 50GB drive.
