[gentoo-user] is harddrive kaput?

[maxim wexler]

Hello everbody,

I was surfing the web when firefox suddenly closed and
attempts at re-opening it failed with strange errors
since forgotten. I decided to bail out of X and
restart it; that failed with an I/O error on /dev/hdb4
where / resides. Couldn't do a shutdown; had to reset
the box. Now I get a kernel panic - Cannot open root
device "hdb4". 

Booted from install CD and ran dmesg:

hdb: dma_intr: error 0x84 {DriveStatusError Bad CRC}
     dma_intr: status 0x51 {DriveReady SeekComplete 
error}          

a bunch of these ending with

ldm_validate_partition_table(): disk read failed.

fdisk displays the partitions all right but attempts
to mount /dev/hdb4 came up with, special device
/dev/hdb4 does not exist.

e2fsck: no such file, bad superblock
tune2fs: couldn't find valid fs superblock

Is my hard-drive toast? This is the same one you may
recall I had so much trouble with a few months back.
Will it be possible to fix? Or at least make readable?

-mw

Hi,

get one of the vendors test-tools, let them run, write down the error message 
and then bring it back - if you still have guarantee. 

You may can try a different cable, but when only one partition died so far, it 
is most probably not the cable.

The short answer is yes. You might be able to recover it by booting from 
a CD distro (gentoo minimal, Knoppix, Fedora Rescue, etc.) and forcing 
fsck to fix it. That might last long enough to get everything important 
off of it. Occasionally you can run badblocks (with the -w option, this 
will take a long time on large and/or slow disks) and find any bad 
sectors. Be sure to use the -o option so you can feed the result into 
mke2fs when you re-format. The -w option is destructive so make sure you 
recover what you need first. If you had trouble with it before, it is 
probably only hours from being a paperweight (if it isn't already).

Hope this helps.
