•
Seven or eight error bytes occurring per interleaving are corrected by the ECC
feature during a read operation.
•
A defective sector is detected and replaced with an alternate sector during a
write operation.
•
An error occurs in one of four sets of media data during media management
information (DMA) write operation caused by the FORMAT UNIT command
(MEDIUM ERROR is set if an error occurs in two, three, or four sets of four
sets).
If the Disable Correction (DCR) bit is 0, the command corrects any correctable
errors detected in a read command. If the DCR bit is 1, the command does not
correct any correctable errors that are detected.
A value of 3 or fewer cannot be specified for Read Retry Count. If 3 or fewer is
specified, the command processing assumes that 4 is specified and reports
Recovered Error.
The value of Write Retry Count must be 3. If a value other than 3 is specified, the
command processing assumes that 3 is specified and reports Recovered Error.
To ensure media compatibility, the read-write error recovery page must contain
the default values, except when the settings are used for a diagnosis.
The values in the Read-write error recovery page can be saved.
