Table 2.2 Disk drive troubleshooting
Item Recommended action
Frequent or repeated seek errors Collect sense data, and see Chapter 3.
Replace the disk drive, and check that the test method is correct. If
the error recurs, it is likely that the disk drive is normal but the test
method is incorrect.
Intermittent or nonfatal errors Replace the disk drive, and check that the test method is correct. If
the error recurs, it is likely that the disk drive is normal but the test
method is incorrect.
To check performance, change the disk drive conditions by changing
the voltage or temperature.
If the disk drive error recurs or a possibly faulty part is found by troubleshooting, return the
complete disk drive to the factory for repair. A media defect list must be included with a disk
drive returned to the factory.
If the possibly faulty part is the disk enclosure, return the whole disk drive to the factory for
repair. Also if a clear error (erroneous servo track information or noisy drive) is detected in the
disk enclosure, return the whole disk drive to the factory. A media defect list must be included
with a disk drive returned to the factory.
CAUTION
Equipment Damage
Never open the disk enclosure in the field. Opening the disk enclosure
in the field may cause an irreparable fault.
