SCSI Description

￿￿￿￿4'<'41The REZERO￿70+6￿%QOOCPFUNIT command￿￿￿￿Jsends￿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 5-194.
