5.1Error rates

The error rates stated in this manual assume the following:

•The drive is operated in accordance with this manual using DC power as defined in paragraph 6.2, "DC power requirements."

•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.
