WebThe earlier drives used physical addresses consisting of cylinder, head, and sector (CHS) number to refer to specific locations on the disk, and the OS had to be aware of the geometry of each disk used. Logical block addressing (LBA) has simplified the addressing by using a linear address to access physical blocks of data. WebAddressing Space For CHS, the maximum number of cylinders supported is 1024, of heads is 16, and of sectors is 63, and the number of bytes per sector is 512. Therefore, the maximum capacity of the supported hard disk is 512 x 63 x 16 x 1024=528 MB.
