Hello,
I have the following output from
>camcontrol defects da2 -f phys -G
Got 5 defects:
914:5:426
2118:2:40
2118:2:41
2119:2:40
2119:2:49
>camcontrol defects da2 -f bfi -G
Got 5 defects:
914:5:218112
2118:2:20480
2118:2:20992
2119:2:20480
2119:2:25088
What does it mean? How can I interpret these data? The drive is IBM
DDYS-T18350M (produced in Nov 2000), the adapter is Adaptec aic7896.
Are there any standards for the number of bad blocks allowed for the disk
during warranty period? Other interesting thing is that
>camcontrol defects da2 -f bfi -G |wc
Got 5 defects:
5 5 65
>camcontrol defects da2 -f bfi -P |wc
Got 6156 defects:
6156 6156 85238
Can such large number of primary defects be considered as normal? Which
defect growth rate may one expect from such figure from this
(modern) drive (it is of course informal question)?
Please cc: your reply to me.
Any information is greatly appreciated!
Thanks a lot,
Alex
