a. Error recovery flags
x EER (enable early recovery)
x PER (post error)
x DTE (disable transfer on error)
x DCR (disable correction)
The definitions and functions of these control flags are the same as for the read/write error
recovery parameters. See item (1) concerning the details.
b. Number of retries during VERIFY
This parameter specifies the number of times reading of the disk media should be retried when
a "Data Check" type error is detected in a read operation. the number of retries specified by
this parameter is the maximum number of times reading of each individual data area in each
logical data block is retried. The IDD retries reading the data area in each data block the
specified number of times. When zero is specified in this field, retrying to read data from the
disk is prohibited.
When X '06' is specified as the page length on Page 1, the IDD applies the value specified in
the Number of retries during READ field on Page 1 to this field also.
c. Correctable bit length
This parameter indicates the burst error length (bit length) that can be applied for data
corrections according to the ECC. This parameter cannot be changed by the INIT. However,
the IDD disregards the value specified in this parameter and operations according to the
"Default" value.
d. Recovery time limit
This parameter specifies the maximum time the TARG can used for error recovery processing,
as a 1ms constant. The value specified in this parameter is the maximum permissible error
recovery processing time for an individual command. When both this parameter and the
"Number of retries during VERIFY" parameter are specified, priority must be given to
whichever parameter specifies the shortest time in its application.
The reported value in this field is a copy of the Recovery time limit in Page 1. The IDD
disregards the value specified in this field.
