RCD

A Read Cache Disable bit of 1 indicates read ahead is
disabled.

A RCD bit of 0 indicates read ahead is enabled.

NOTE

If WCE and RCD are both set to 1, a CHECK CONDITION status is
returned with the sense key/additional sense code set to ILLEGAL
REQUEST/Invalid Parameter List.

DisablePre-fetchTransfer
Length

This field sets the threshold value for pre-fetching data
during reads. If the number of blocks to be read is
greater than this value, no pre-fetching occurs.

The Disable Pre-fetch Transfer Length default setting
is 64.

Minimum
Pre-fetch

If this bit is set to 0 by the MODE SELECT command, a
CHECK CONDITION status is returned with the sense
key/additional sense code set to ILLEGAL REQUEST/
Invalid Parameter List. Since the MF bit is 1 and the
Minimum Pre-Fetch bit is also 1, the minimum pre-
fetch size is equal to the READ Transfer Length. This
field does not affect the operation of the drive.

The Minimum Pre-fetch default setting is 1 and cannot
be changed.

Maximum
Pre-fetch

If this bit is set to 0 by the MODE SELECT command, a
CHECK CONDITION status is returned with the sense
key/additional sense code set tot ILLEGAL REQUEST/
Invalid Parameter List. Since the MF bit is 1 and the
Maximum Pre-fetch bit is also 1, the maximum pre-
fetch size is equal to the READ Transfer Length. This
field does not affect the operation of the drive.

The Maximum Pre-fetch default setting is 1 and cannot
be changed.
