Table 76 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, whether the sector of data is initialized correctly is not
verified with read operation. 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 internally,
the device will always format a track in the same way no matter what sector numbering is specified in the format
table.
