SCSI Description
Maxtor Atlas 10K III 5-81
RPL 00b
Rotational Position Locking is used for spindle synchronization in
storage arrays. The modes are:
00b – Disabled
10b – Master
01b – Slave
11b – Not supported
RPL can be overridden if the Maxtor (Vendor) Special Function
Control page Auto field value = 1.

Rotational Offset 0
Rotational Offset indicates the amount of rotational offset that
the drive uses when synchronized. The rotational offset is applied
in the retarded direction (lagging the synchronized spindle mas-
ter). The value in the field is determined by the following formula:
Offset
= 0 … 255
256
For example, a numerator of 128 indicates an offset of 1/2 revo-
lution (180°).
The valid parameter values are 0 to 255.
The specified value may be rounded. Rotational offset is not used
when the drive is configured as the synchronized-spindle master.
