Figure 79. Format Track (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 transfers a sector of data containing a format table to the device. The format table should
contain two bytes for each sector on the track to be formatted. The structure of format table is shown in
Figure 80 page 95. The first byte should contain a descriptor value and the second byte should contain
the sector number. The descriptor value should be 0 for a good sector, and any other descriptor value
will cause an aborted error. The remaining bytes of the sector following the format table are ignored.
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.
