H The head number of the track to be formatted. ( L = 0 )
In LBA mode, this register specifies LBA address bits 24 - 27 to be formatted. ( L = 1 )
Input Parameters From The Device
Sector Number In LBA mode, this register specifies current LBA address bits 0-7. ( L = 1 )
Cylinder High/Low In LBA mode, this register specifies current LBA address bits 8 - 15 (Low), 16 - 23
(High)
H In LBA mode, this register specifies current LBA address bits 24 - 27. ( L = 1 )
Error The Error Register. An Abort error ( A B T = 1 ) will be returned under the following
conditions:
The descriptor value does not match the certain value. (except 00h, 20h, 40h and
80h)
The number of assign(40h) exceeds the maximum number of reassign table entry.
N o spare data sector to be assigned.
In LBA mode, this command formats a single logical track including the specified LBA.
Explanation for descriptor
Descriptor : 00h The sector of data will be initialized to 00h.
Descriptor : 20h The sector will be unassigned to the original location from the reassigned location.
Descriptor : 40h The sector will be assigned to a spare data sector. When being accessed by next
command, the spare sector of data will be used automatically. The assigned sector
can be unassigned with a descriptor 20h.
Descriptor : 80h The sector will be registerred as a bad sector. Thereafter, the sector reports BAD
BLOCK to E R R O R Register on Read commands.
But the sector will not report
BAD BLOCK if the sector is written by Write commands.
