hicksd8 : fsck is not helping, I tried it with different options. It comes up clean.

rbatte1 : I can run analyze and read and I can see, what blocks are corrupted. But There are large number of blocks, which need to be fixed with repair option in format. So looking for that script.

MadeInGermany : These are two scripts or I should both one by one as it is ?

The first one is just a demonstration that it works.
It does nothing than print the partition table.
You can type it at (or copy it to) the command line.

Yes, it might do because it's not being told to check everything. A -o full should check every last byte is readable and report errors.

hicksd8 : Tried fsck, no luck
Code:
# fsck -o f /dev/rdsk/c0t0d0s0
** /dev/rdsk/c0t0d0s0
** Last Mounted on /a
** Phase 1 - Check Blocks and Sizes
** Phase 2 - Check Pathnames
** Phase 3a - Check Connectivity
** Phase 3b - Verify Shadows/ACLs
** Phase 4 - Check Reference Counts
** Phase 5 - Check Cylinder Groups
91388 files, 4328341 used, 5989667 free (3747 frags, 748240 blocks, 0.0% fragmentation)

It is not accepting "full" syntax
Code:
# fsck -o full /dev/rdsk/c0t0d0s0
ufs usage: fsck [-F ufs] [-m] [-n] [-V] [-v] [-y] [-o p,b=#,w,f] [special ....]

You must give the sectors as arguments.
Say you want to repair absolute sectors 39594665 and 39594666
Code:
/tmp/repair_sector 39594665 39594666

fsck is useless here. It does not repair defective sectors, it repairs logical errors in the filesystem.
