REZERO UNIT Command (01h)

The REZERO UNIT command sends the heads to cylinder 0 (Logical Block Address
0). Once the heads are on the track, they are not guaranteed to stay at cylinder 0;
periodic calibrations may send them to a different cylinder. If periodic calibrations
have been disabled by using the MAN bit (byte 3, bit 6) of the Vendor Unique
Function Control Page in the MODE SELECT command (15h), the REZERO UNIT
command will cause the drive to perform the next scheduled calibration. The data
format is shown in Table 5-188.
