Maxtor 10K V - Manual (Page 58)

4-10 Maxtor Atlas 10K V
4.11 RELIABILITY
Component Life: 5 years
Preventive Maintenance (PM): Not required
Contact Start/Stop: 50,000 cycles at ambient,
35,000 at Environments
Annualized Failure Rate (AFR)
No greater than 0.58 percent
Drive reliability is closely related to the temperatures the drive is exposed to. The
AFR is based on an operational design temperature ambient of 86° F (30° C)
4.12 DISK ERRORS
Table 4-9 provides the error rates for the Maxtor Atlas 10K V hard disk drive.
Table 4-9
Error Rates
1. 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.
2. Uncorrectable read errors are those that are not correctable using an Error
Correcting Code (ECC), or retries within the retry limits specified in the
mode pages. The drive terminates the command either when a repeating
error pattern occurs, or after both the specified number of retries and
application of triple burst error correction fail to correct the error.
3. A seek error occurs when the actuator fails to reach or remain on the
requested cylinder, and/or the drive requires the execution of the full
calibration routine to locate the requested cylinder.
