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
