The
cylinder skew factor
12
field indicates the number of
physical sectors between the last logical block of one
cylinder and the first logical block of the next cylinder. The
actual cylinder skew factor that the drive uses depends
on the zone. The default value is 0034
H
, which is the
cylinder skew factor for the first zone.
Byte 20
The
drive type field bits are defined as follows:
The
soft sectoring (SSEC) bit is set to 1. This bit is
reported as not changeable. Although it can be set to
satisfy system requirements, it does not affect drive per-
formance.
The
hard sectoring (HSEC) bit is set to 0. This bit is
reported as not changeable. Although it can be set to
satisfy system requirements, it does not affect drive per-
formance.
The
removable media (RMB) bit is always set to 0, indi-
cating that the drive does not support removable media.
This same bit is also returned in the Inquiry parameters.
The
surface map (SURF) bit is set to 0, indicating that the
drive allocates successive logical blocks to all sectors
within a cylinder before allocating logical blocks to the
next cylinder.
