[Sunhelp] Problem on external Hard Drive

[Aryanto Rachmad]

Hello All,

I have a problem with SCSI external hardisk of my Sun SPARC/10.
I received this following message after I reboot this machine:

.
/dev/rdsk/c0t5d0s7: CANNOT READ: BLK 16
/dev/rdsk/c0t5d0s7: UNEXPECTED INCONSISTENCY; RUN fsck MANUALLY
.

But after I executed the fsck command, I got this message:
      
# fsck -F ufs /dev/rdsk/c0t5d0s7
** /dev/rdsk/c0t5d0s7

CANNOT READ: BLK 16
CONTINUE? yes

THE FOLLOWING SECTORS COULD NOT BE READ: 16 17 18 19 20 21 22 23
 24 25 26 27 28 29 30 31
# 

So, I decided to re-format this hardisk using format command, but
the problem still occur. I have already tried to change the partition
and format it again, but it still did not fix the problem.

Do I need to do a low level format? If so, how to do a low level
format on Solaris 2.5.1 environment? Could someone tell me how to
include this bad block in the defect list? Could you please give
some advice what should I do?

The following is the configuration of that hardisk:

format> inquiry
Vendor:   SEAGATE 
Product:  ST11200N SUN1.05
Revision: 9500

format> current
Current Disk = c0t5d0
