Unhappy


Code:
e2fsck -b 8193 /dev/hdb3
e2fsck 1.39-WIP (31-Dec-2005)
e2fsck: Bad magic number in super-block while trying to open /dev/hdb3

The superblock could not be read or does not describe a correct ext2
filesystem.  If the device is valid and it really contains an ext2
filesystem (and not swap or ufs or something else), then the superblock
is corrupt, and you might try running e2fsck with an alternate superblock:
    e2fsck -b 8193 <device>

My apologies, but if that's definitely an ext2/ext3 filesystem it's beyond what I can fix. The information I saw on the web related to data recovery was at http://kerneltraffic.org/slug-pearls...3_print.html#2 and http://www.progsoc.uts.edu.au/lists/.../msg00641.html, but I wouldn't recommend trying those without backing up the drive first.

Okay, I don't have another drive to back it up from but I do have a 60GB windows FAT32 partition I am more than happy to clear and move the recovered things like emails, turboprint keys and etc, so this means a reinstall? I then will install MEPIS on it but this thread is NOT over until I am back to regular working order, so what can I do?

I don't use Mandriva so I don't know what the default partition type is
usually ext3

If you look at the "learn dd command" thread in LQ you may find
a way to backup the whole partition so you can mess with it as much
as you want. You may need dd_rescue rather than dd

You may also look in the future into smart HD attributes and a package called
smartmontools to monitor the health of your HD. I was going to say do not run it now, it has the potential to make a very failing drive a failed drive.
Otherwise if use "normally" it would tell you if a drive is possibly starting to fail. It is your choice. I gave you the utmost cautious advice.

try e2fsck.ext3 instead of e2fsck (should make no diff, but still try)

'syslog' , except I don't know where the 'syslog' in my mandriva 2006
Fair enough. Do not want to patronise you. If you had googled you would have found
the answer in 1 min. Beside with the live distro you could even find it with konqueror. When you solve all your problem find some time to learn a command called
"locate". You will need to install the package first.

People will expect from you some homework. You may cringe because you may have
an "urgent problem". But look you are getting a fair bit of good help from various people. This is the way it works (at least in my books)

I am no expert BTW
once HD partition is backed up you can also try
e2fsck -fy
Force checking even if the file system seems clean. and yes to evthg

I do not think you are out of options yet
As an example you can test the HD
Western Digital's "Data Lifeguard Diagnostic" http://support.wdc.com/

there is advanced tools like the "coronary's kit" so there are
ways to recover files. I have no experience to guide you with this.

What? It seems that you're getting me to do things, then it also seems that you've nailed down the exact problem and solution of what I have (which you have not) . But for good measure I ran Powermax 4.22 and both Advanced test and QuickTest came back perfectly so no, my hdd is NOT failing.
Backup and recover files. Why? You havent said what the problem is. We're not even sure yet. We still have not completed the diagnostic! I don't want to backup my hdd, as I have nothing to 'back it up' to! I am particularly scared of this:
once HD partition is backed up you can also try
e2fsck -fy

are you implying that damage may occur? only then will I then run it. After all this work we are not even close to fixing the problem. Thanks for any more help, and if it is impossible due to the users on this board not being expert enough I am going to subscribe to experts-exchange.com and get my solution.

You really have attitudes
Please learn from all the other messages
Never claimed I had solved anything or nailed anything.
None of us have a crystal ball, we only make suggestions.
At the end of the day, your system, your choices, your problem.

Your problem, not that of anybody on the board, do you get it?

Farewell
You might have come to the wrong place then
Go and pay for your support

I hope you have learn a few things,including how boards work.

Bye again

Backup and recover files. Why?
If you run dd you can make a perfect copy of your partition, including errors
and whatsnot. So then you can try to rescue the orginal partition (& files)
If you messed it up then you can always return to your initial point.
You might not be able to dd to a fat32 partition, do not know.
You may still divide it...

You knew it, we did not. It is one thing out the way.
Are you not glad we asked? It would have been better if you had told us first

Quote:
But for good measure
Any other good measure, have you got any backups?
This is meant to be sarcastic this time.

Fair enough. It meant to be. You should be.
I possibly was giving good advice by advocating a cautious route, maybe not

BTW, you have lost my help.

A piece of advice, pay for the help if the data are worthy to you.
If the data are worthy, consider buying a spare HD to dd to it

This is the first time I withdraw my help. Sorry about that.

If you had this aptitude as a mechanics would you change
a engine gasket and the breaks?
DIY at your risks, ok.

No, I don't have anything important on the hdd, so yeah I will then go ahead and do that 'fy' command and see what happens. But it would sure help if we got this thing solved.
