Changeable values in the read-write recovery | Fujitsu MCM3064AP

Host Interface

When the PER (Post Error) bit is 0, the command reports the GOOD status when it recovers the normal state by using the error recovery process. When the bit of PER is 1, the command reports the CHECK CONDITION status when it recovers the normal state by using the error recovery process. At this time, Sense key is set with RECOVERED ERROR.

RECOVERED ERROR is reported:

•

•

•

When 7 to 8 error bytes per interleaving was corrected by the ECC correction during read operation

When a defect sector is detected and replaced with an alternate sector during a write operation

When an error occurs in one of four sets of media data during media management information (DMA) write operation with the FORMAT UNIT command (MEDIUM ERROR is set if an error occurs in two, three, or four sets of four sets.)

When the DCR (Disable Correction) bit is 0, the command corrects errors if a correctable error is detected in the READ (10) and READ (12) command. When the bit of DCR is 1, the command does not correct errors even if a correctable error is detected.

Read Retry Count must not be 3 or smaller. If a value of 3 or smaller is specified, the command assumes 4 and reports Recovered Error.

Write Retry Count must not be a value other than 3. If a value other than 3 is specified, the command assumes 3 and reports Recovered Error.

To assure media compatibility, the read-write error recovery page should be set to the default value, except for diagnostics purposes.

The read-write error recovery page can be saved.
