Most common USB drives can handle 9x512, 18x512 and 8x1024 sector
formats, assuming that the ID headers follow the usual conventions
(sector 1 = 1, head 0 = 0, cylinder = actual). That last format was
mostly used by the NEC PC98 series.
Essentially they're tri-mode drives that understand plain old DOS
(and DOS-V) type formats. The command structure is basically SCSI-
