bad block on jaz drive

I was able to find fsrd at Armory.com

As the readme file explains:

"Utility `fsrd` is primarily targeted for situations where file system cannot be mounted (not even read-only) or super-block cannot be read at all."

It understands SCO XENIX, S51K, ES51K, AFS, EAFS and HTFS.

Have you tried mounting the Jaz cartridge with read-only option ?

  mount -r /dev/<JazFileSystem> /mnt

Try this, it usually works.

Alternatively, you may want to try `scsibadblk` command to scan the Jaz
cartridge for bad blocks and remap those blocks, then trying to use `fsck` again.

If you won't be able to mount this Jaz cartridge, download

<http://members.xoom.com/rts101/tmp/fsrd> or
<ftp://ftp.mediumsoft.cz/private/rts/tmp/fsrd> and do this:
(links dead, sorry)


  dev="/dev/<Jaz>"
  ./fsrd -e ${dev} dir -ir | ./fsrd -e ${dev} inode -v -dc - |
    ( cd <backup-dir>; cpio -iduvm )

to restore all files/directories.

Many of the products and books I review are things I purchased for my own use. Some were given to me specifically for the purpose of reviewing them.

Specific links that take you to pages that allow you to purchase the item I reviewed are very likely to pay me a commission.

These gifts and referral fees do not affect my opinions; I often give bad reviews anyway.
