H This indicates the head number of the track to be formatted. (L = 0)
In LBA mode this register specifies that LBA address bits 24–27 are to be
formatted. (L = 1)
Input Parameters From The Device
Sector Number In LBA mode this register specifies the current LBA address bits as 0–7 (L = 1).
Cylinder High/Low In LBA mode this register specifies the current LBA address bits as 8–15 (Low)
and bits 16–23 (High).
H In LBA mode this register specifies the current LBA address bits as 24–27 (L = 1).
Error This indicates the Error Register. An Abort error (ABT = 1) will be returned under
the following conditions:
! The descriptor value does not match the certain value (except 00h).
In LBA mode this command formats a single logical track including the specified
LBA.
