Figure 97. 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 write operation. At this time the sector of data is not verified with read
operation whether the sector of data is initialized correctly. Any data previously stored on the track will be
lost.
The host may transfer a sector of data containing a format table to the device. But the device ignores the
format table and writes zero to all sectors on the track regardless of the descriptors.
Since device performance is optimal at 1:1 interleave and the device uses relative block addressing inter-
nally, the device will always format a track in the same way no matter what sector numbering is specified
in the format table.
Output parameters to the device
Sector Number In LBA mode this register specifies the formatting of LBA address bits 0-7. (L=1)
Cylinder High/Low The cylinder number of the track to be formatted. (L=0)
In LBA mode this register specifies the formatting of LBA address bits 8-15 (Low),
16-23 (High). (L=1)
H The head number of the track to be formatted. (L=0)
In LBA mode this register specifies the formatting of LBA address bits 24-27.
