4-3-2. Error Counter Display Menu (D0)
The D0 : ERROR COUNTER menu is used to display the
error generation history (error counter) of a hard disk
drive.
The five error counters below are available.
Use the value of these error counters as the reference of
hard disk drive replacement or disk cleaning period.
Error counters
. Recovered/RECOVERED error counter
This counter displays the number of times when the
detected error is normally recovered by the retry opera-
tion of a hard disk drive. This counter is used for
inspection at the factory. It is not related to the abnor-
mality in a hard disk drive.
. Medium/MEDIUM error counter
This counter displays the number of sectors in which a
media error occurs. The detected error is counted when
it is not recovered by the retry operation of a hard disk
drive. However, the media error is not counted when it
is generated in the same sector.
This counter is reset to "0" when disk cleaning (D9) is
executed.

Picture may be momentarily frozen or sound may be
intermitted during REC/PB operation in the disk when a
media error occurs in a hard disk.
. Medium(Total)/MEDIUM(T) error counter
This counter displays the total number of sectors in
which a media error occurs. This counter is not reset
even if disk cleaning (D9) is executed.
If the counter value reads ten or more, replace the hard
disk drive corresponding to the ID number. When the
counter value reads ten, an image may be frozen or a
sound may be interrupted.
. Hardware/HARDWARE error counter
This counter displays the number of times when a
hardware error occurs in a hard disk drive. If a hardware
error occurs once, replace the hard disk drive corre-
sponding to the ID number.
. Others/OTHERS counter
This counter is used for inspection at the factory. It is
not related to the abnormality in a hard disk drive.
