2.1.4Error rate

Errors detected during initialization and replaced by alternate block assignments are not included in the error rate. Data blocks to be accessed should be distributed over the disk medium equally.

(1)Unrecoverable error rate

Errors which cannot be recovered within 63 retries and ECC correction should not exceed 10 per 1015 bits.

(2)Positioning error rate

Positioning errors which can be recovered by one retry should be 10 or less per 108 seeks.

2.1.5Reliability

(1)Mean Time Between Failures (MTBF)

MTBF of the IDD during its life time is 1,000,000 hours (operating: 24 hours/day, 7 days/week

average DE surface temperature: 40°C or less).

Note:

The MTBF is defined as:

Operating time (hours) at all field sites

MTBF =

The number of equipment failures (*1) from all field sites

*1 Failure of the equipment means failure that requires repair, adjustments, or replacement. Mishandling by the operator, failures due to bad environmental conditions, power trouble, host system trouble, cable failures, or other failures not caused by the equipment are not considered.
