Table 4-9 provides the error rates for the Maxtor D540X-4K hard disk drives.
6CDNG   Error Rates
1. Retry recovered read errors are errors which require retries for data correction.
Errors corrected by ECC on-the-fly are not considered recovered read errors.
Read on arrival is disabled to meet this specification. Errors corrected by the
thermal asperity correction are not considered recovered read errors.
2. Unrecovered read errors are errors that are not correctable using ECC or retries.
The drive terminates retry reads either when a repeating error pattern occurs, or
after the programmed limit for unsuccessful retries and the application of
quadruple-burst error correction.
3. Seek errors occur when the actuator fails to reach (or remain) over the requested
cylinder and the drive requires the execution of a full recalibration routine to
locate the requested cylinder.
Note: Error rates are for worst case temperature and voltage.
