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 does not verify the
correct initialization of the data sector. 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
