5.0Reliability specifications

The following reliability specifications assume correct host and drive operational interface, including all inter- face timings, power supply voltages, environmental requirements and drive mounting constraints.

Seek error rate:Less than 10 errors in 108 seeks

Read Error Rates

Recovered Data

Unrecovered Data

Miscorrected Data

Interface error rate:

MTBF

AFR

Preventive maintenance:

5.1Error rates

The error rates stated in this manual assume the following:

•The drive is operated per this specification using DC power as defined in this manual (see Section 6.2).

•Errors caused by host system failures are excluded from error rate computations.

•Assume random data.

•Default OEM error recovery settings are applied. This includes AWRE, ARRE, full read retries, full write retries and full retry time.

•Error rate specified with automatic retries and data correction with ECC enabled and all flaws reallocated

5.1.1Recoverable Errors

Recoverable errors are those detected and corrected by the drive, and do not require user intervention.

Recoverable Data errors use retries and correction. Application of ECC on-the-fly correction alone is not con- sidered a Recovered Data error.

Recovered Data error rate is determined using read bits transferred for recoverable errors occurring during a read, and using write bits transferred for recoverable errors occurring during a write.

5.1.2Unrecoverable Errors

Unrecoverable Data Errors (Sense Key = 03h) are specified at less than 1 sector in error per 1016 bits trans- ferred. Unrecoverable Data Errors resulting from the same cause are treated as 1 error for that block.
