a.
Error recovery flags

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.
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 be 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.
4-44
EER (enable early recovery)
PER (post error)
DTE (disable transfer on error)
DCR (disable correction)
