Modern disk drives manage the data stored on them as a collection of fixed length data blocks. Each block is identified with a logical block number (LBN) and a drive is generally formated so that blocks are most efficiently accessed in order of ascending logical block number. Drive protocols such as SCSI generally allow one to specify an LBN and a block count in read and write commands, under the shared assumption that blocks will be accessed in ascending order from the starting LBN.
