EER (Enable Early Recovery)
1

The disc drive applies on-the-fly T>1 ECC correction as soon as possible, before attempting other retry mecha-
nisms, and without reporting successful corrections to the host as recovered error. Seek error retries and message
system errors are not affected by this bit. When this bit is set to 1, the DCR bit must be zero (0).

0

The disc drive applies ECC correction before other retry mechanisms, but does not perform T>1 corrections on the
fly; any successful correction will be reported to the host as a recovered error.

Page Code
07h

Verify Error Recovery page code.

Page Length
0Ah

This field specifies the length of the parameter that follows (in bytes).

PER (Post Error)
1

The disc drive reports Check Condition status and appropriate sense key for any recovered errors encountered.
Reporting of unrecoverable errors has priority over reporting of recoverable errors.

0

Any errors recovered within the limits established by the other Error Recovery Flags are not reported. Any unrecov-
erable errors are reported.

PS (Parameter Savable)
Used only with the Mode Sense command. This bit is not used with the Mode Select command.
1

The target is capable of saving the page in a nonvolatile vendor-specific location.

Verify Correction Span
The size (in bits) of the largest burst data error for which data error correction may be attempted. If the drive does not imple-
ment this field, a value of zero (0) is returned in Mode Sense data.

Verify Recovery Time Limit

The maximum time (in increments of one millisecond) that the drive uses error recovery procedures to recover data for an
individual logical block. If the verify retry count and the verify recovery time limit are both specified, the one that requires the
least time for a data error recovery actions has priority. The drive may round this value.

Verify Retry Count
The number of times the drive will attempt its recovery algorithm during a verify operation. If the verify retry count and the
verify recovery time limit are both specified, the one that requires the least time for data error recovery actions has priority.
