Figure 83. Format Track command (50h)
The Format Track command formats a single logical track on the device. Each good sector of data on the
track will be initialized to zero with the write operation. At this time, the read operation is not verified for
the correct sector of data initialization.
Any data previously stored on the track will be lost.
Output Parameters To The Device
Sector Number
In LBA mode this register specifies that LBA address bits 0–7 are to be
formatted. (L = 1)
Cylinder High/Low
This indicates the cylinder number of the track to be formatted. (L = 0)
In LBA mode this register specifies that LBA address bits 8–15 (Low) and bits
16–23 (High) are to be formatted. (L = 1)
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).
