|
|
0 | 0 | 0 | 0 | 1. | Rereading is tried repeatedly up to the number of times specified in the "Read |

|
| Retry Count", "Write Retry Count" or "Verify Retry Count" parameter. If |
|
|
|
|
| possible, data correction is executed afterward according to the ECC. |
|
|
|
| 2. | When error recovery has succeeded, processing of the command is continued. |
|
|
|
| 3. | The contents of recovered errors are not reported. |

|
|
|
| 5. | Transfer of data in blocks which include unrecoverable errors to the INIT is |
|
|
