Note:
If transfer of this page descriptor is requested by the MODE SENSE or MODE SENSE
EXTENDED command, the IDD reports X '0A' as the page length (byte 1). However, if either
X '0A' or X '06' is specified for the page length in the MODE SELECT or MODE SELECT
EXTENDED command, the IDD treats it as though the correct page length was specified. If X
'06' is specified for the page length, the value specified in the "Number of retries during READ"
field is used as is in the "Number of retries during WRITE" field and the value specified in the
"Number of retries during READ" field is also used as is in the "Number of retries during
VERIFY" field. The X '06' page length is included in consideration of compatibility with
previous models, but as much as possible, it is recommended that the INIT use the X '0A' page
length.
Error recovery parameters defined in this page descriptor are applicable for the following
commands, except in cases where it is specifically pointed out.
