THE RELIABILITY PROGRAM FOR MODEL 6234
•
The reliability program tests the subsystem for maximum disk
activity and data transfer. Optional addressing and data patterns can
be selected when running random and sequential exerciser programs.
Seek exercisers check timing using converging/diverging and random seek
patterns. The program executes a string of individual tests. A
detailed log of all surface related addresses, as well as a summary of
all errors and seek/write/read statistics is available by keyboard
request.
CAUTION
The reliability program writes on the entire disk. If
the disk cannot be backed up, do not run the reliability
program.
Do not run 504 FORMAT unless absolutely necessary. All
bad sector information will be lost. The 504 VERIFY
program does flag bad sectors but may not find as many as
the special test equipment used in the manufacturing test.
NOTE
Specific areas of the disk may be tested using a min/max
Head/CYL option contained in the reliability program.
