Logical Block Addressing


(LBA) A href="module.php?name=Lexikon&file=search&eid=1&query=hard disk">hard disk href="module.php?name=Lexikon&file=search&eid=1&query=sector">sector addressing scheme used on all href="module.php?name=Lexikon&file=search&eid=1&query=SCSI">SCSI hard disks, and on href="module.php?name=Lexikon&file=search&eid=1&query=ATA-2">ATA-2 conforming href="module.php?name=Lexikon&file=search&eid=1&query=IDE">IDE hard disks. The addressing conversion is performed by the hard disk firmware. Prior to LBA, combined limitations of href="module.php?name=Lexikon&file=search&eid=1&query=IBM PC">IBM PC href="module.php?name=Lexikon&file=search&eid=1&query=BIOS">BIOS and href="module.php?name=Lexikon&file=search&eid=1&query=ATA">ATA restricted the useful capacity of IDE hard disks on IBM PCs and compatibles to 1024 cylinders * 63 sectors per track * 16 heads * 512 bytes per sector = 528 million bytes = 504 megabytes. Modern BIOSes select LBA mode automatically, and work around the 1024-cylinder BIOS limit by representing a hard disk to the OS as having e.g. half as many cylinders and twice as many heads. However, there is still an unbreakable BIOS disk size limit of 1024 cylinders * 63 sectors per track * 256 heads * 512 bytes per sector = 8 gigabytes, but modern OSes (including href="module.php?name=Lexikon&file=search&eid=1&query=Windows 9x">Windows 9x, href="module.php?name=Lexikon&file=search&eid=1&query=Windows NT">Windows NT and href="module.php?name=Lexikon&file=search&eid=1&query=Linux">Linux) are not affected by it, since they issue direct LBA-based calls, bypassing the BIOS hard disk services completely.
