All USB drives and other drives of recent vintage support logical block addressing (LBA). With LBA, blocks of storage capability are numbered sequentially beginning at zero. All blocks have the same size, again typically 512 bytes. The logical block address is often referred to as a sector address because the block size equals the capacity of a sector in a hard drive. To access the media, software specifies the logical block address to read or write to. For hard drives, the drive’s controller translates each LBA to a cylinder, head, and sector on the drive. For flash drives, the drive’s. | MICROCONTROLLERS CHAPTER 2 ADDRESSING METHODS Dr. Vo Tuong Quan HCMUT - 2011 Addressing Methods The Addressing Methods Use to know the source address and destination address of data 1.
