MODE SELECT parameters:  additional error recovery parameters
a.
RPR (rounded parameter report)
This bit stipulates the operation in the case where rounding up or rounding down processing of
a MODE SELECT parameter is performed.
"1"  : If rounding up or rounding down processing of parameters in the MODE SELECT
command has been performed, a CHECK CONDITION status is reported.
"0"  : Even if rounding up or rounding down processing has been performed, a GOOD status
is reported and the command is terminated normally.
When this bit is set to "1," and "Round-up" or "Round-down' processing is performed by the
MODE SELECT command, "CHECK CONDITION" status is reported.  The factory setting
for this bit is "0."
The IDD ignores the value set by this parameter.  Whether or not to report the "CHECK
CONDITION" is determined by the type of error.
b. Number of retries during a seek error
This parameter specifies the number of times repositioning is retried when a seek error is
detected.  When zero is specified in this field, repositioning retries are prohibited.  The value
specified in this field is applicable for all commands which are accompanied by a seek
operation.
c.
RFJ (reserved by Fujitsu)
All the bits in byte 3 are reserved by Fujitsu.  The user should specify "0" in this bit.
