Help: root partition crashed, fsck failed. Disk problem?

recently this sunfire 280R (solaris 10) is having problme, it was able to boot up, then all suddent, it failed, and I can't even mount the first disk which contains root partition when I boot up from cdrom.

2 X 36G hard drive,

I scan first hard drive by "read", there is no bad block. The strange thing is that I can't issue "refresh" or "test", it keeps saying the disk is write protected. (I boot from cdrom as well to single user mode).

Partition:

Code:

Part      Tag    Flag     Cylinders         Size            Blocks
  0       root    wm    1936 - 24619       31.25GB    (22684/0/0) 65534076
  1       swap    wu       0 -   361      510.65MB    (362/0/0)    1045818
  2     backup    wm       0 - 24619       33.92GB    (24620/0/0) 71127180
  3 unassigned    wm       0                0         (0/0/0)            0
  4 unassigned    wm       0                0         (0/0/0)            0
  5 unassigned    wm       0                0         (0/0/0)            0
  6 unassigned    wm       0                0         (0/0/0)            0
  7        var    wm     363 -  1935        2.17GB    (1573/0/0)   4544397

Here is the result for fsck.

Code:

# fsck /dev/dsk/c1t0d0s0

fsck ran successfully, but I still can't mount that root partition.

Code:

# mount /dev/dsk/c1t0d0s0 /a
WARNING: Error accessing ufs log for /a; Please run fsck(1M)
mount: I/O error
mount: cannot mount /dev/dsk/c1t0d0s0

Help please!!!

I'm not sure, but Can you try

Code:

fsck -y fsck /dev/rdsk/c1t0d0s0

option -y : yes for all question

I think it should fsck for raw device (rdsk).

Ratcha.
