SSD-DXXX(I)-4300 DATA SHEET

DRIVE/HEAD REGISTER

The Drive/Head register is used by the host and the device to select the type of addressing (CHS or LBA), the drive letter, and either bits 3-0 of the head number in CHS mode or logical block number bits 27-24 in LBA mode.

Description

 

 

6

LBA. Selects between CHS (0) and LBA (1) addressing mode.

4Drive Address (DRV). Indicates the drive number selected by the host, either 0 or 1.

3-0 HS3 to 0. Indicates bits 3-0 of the head number in CHS addressing mode or LBA bits 27-24 in LBA mode.

•CHS to LBA conversion: LBA = (C x HpC + H) x SpH + S -1

•LBA to CHS conversion:

C = LBA/(HpC x SpH)

H = (LBA/SpH) mod (HpC)

S = (LBA mod(SpH)) + 1

...where:

C is the cylinder number H is the head number S is the sector count

HpC is the head count per cylinder count SpH is the sector count per head count (track)
