Harddisk failure..? [SOLVED]

[OleWilly]

Hi

I heard some strange sounds from my box which have worked fine now for several months. - And the screen went black and I could not do anything but pull the plug. Then I tried to make a safe boot. I did not succeed. Then I started a live cd. I tried to make a new install but I could not. Then I tried to go into my /home to see if I could save some of my work there but there came an error message. If I in a console do this:

[guest@localhost guest]$ dmesg | tail
sd 0:0:1:0: [sda] Unhandled error code
sd 0:0:1:0: [sda] Result: hostbyte=DID_BAD_TARGET driverbyte=DRIVER_OK
sd 0:0:1:0: [sda] CDB: Read(10): 28 00 00 00 00 41 00 00 02 00
end_request: I/O error, dev sda, sector 65

end_request: I/O error, dev sda, sector 33367070
EXT4-fs (sda6): unable to read superblock
[guest@localhost guest]$

Has my hd died ?

Hi OleWilly - until someone with more expertise than myself comes along can I just suggest you don't try to install anything just yet otherwise it may overwrite some of your important data.

[Ramchu]

Use the live CD and download system rescue CD and burn it to CD

Main page :  http://www.sysresccd.org/Main_Page

Download page : http://www.sysresccd.org/Download

it is a live CD and you can possibly recover your files

[Xenaflux]

don't you have an old HD lying around.
If yes, put that in your box and install any linux os on it ( 10 minutes work ).
Then mount your faulty HD
You can now save your data....I hope

Good luck

This is what I did a few months ago.
Using the LiveCD was unsuccessful in my case.
( No clue as why )

Hi

Thanks a lot!

I get this if I try to install:

An error while accessing '98.6 GiB Hard Drive', the system responded:
org.freedesktop.Hal.Device volume.UnknownFailure: mount: wrong fs type,
bad option, bad superblock on /dev/sda6, missing codepage or helper
program, or other error    In some cases useful info is found in syslog -
try    dmesg | tail or so

Running from the LiveCD do a file system check on the partitions.
Do NOT try installing anything.

In a terminal

fsck --help

to see what is to be done.

The partition must be UNmounted to do this safely.

Hopefully running the fsck will sort out the problems.
Be aware it may need to be run on more than one partition.

regards.

Hi

Thanks. - That is not what You get when booted from a live cd. -  Wonder what the command would be to check a fs on a hd which can not be accessed in a normal way.

Not sure what you mean .....   

You find the dev node of the partition you wish to check ........  /dev/sdxy

Then follow the information I posted above

fsck -n /dev/sdxy .......  change xy to whatever they should be for the partition you want to check.

If it appears that will correct some errors then you can run it without the -n (No changes when present)

You might also want to use the  -v  option to get the fullest info ....

Hi

I tried this:

[root@localhost guest]# fsck -n /dev/sda5
fsck from util-linux-ng 2.16.2
e2fsck 1.41.12 (17-May-2010)
fsck.ext2: Attempt to read block from filesystem resulted in short read while trying to open /dev/sda5
Could this be a zero-length partition?
[root@localhost guest]# fsck -n /dev/sda6
fsck from util-linux-ng 2.16.2
e2fsck 1.41.12 (17-May-2010)
fsck.ext2: Attempt to read block from filesystem resulted in short read while trying to open /dev/sda6
Could this be a zero-length partition?
[root@localhost guest]# fsck -n /dev/sda1

Hi

If I try to erase the whole disk I get this:

[root@localhost guest]# dd if=/dev/zero of=/dev/sda
dd: writing to `/dev/sda': Input/output error
1+0 records in
0+0 records out
0 bytes (0 B) copied, 0.00687116 s, 0.0 kB/s

Oh well .....  if you want to wipe and not recover the partition OK.

Check your data cable connected to the drive .....  it likely came a little loose and the superbolck is corrupted .......  at least that is one theory.

If that is the case then you can if you wish use one of the backup superblocks to recover the partition or you can delete the partition or the whole disk as you wish.

Hi

I removed the live cd and looked into the box. I gave the hd cables an extra pressure and switched the power on and PCLinuxOS was flying again fully updated and with all my home stuff.   Thanks a lot for all the advices and help. I think that it was eventually the 4 line powercable that was a bit loose.
