knoppix rescue cd and have tried to mount the partition but it gives me and error with the superblock. When i try mounting using the mount
You can use the second/third/fourth superblock on the partn. First make a copy of the partition using dd, then make another copy. Work on the second copy.
Some hints here: http://www.livejournal.com/users/bluesmoon/15783.html and here: http://www.livejournal.com/users/bluesmoon/109782.html

Philip,
Nice link there. Am trying to figure out how to go about......since the disk seems to have bad sectors. Even a fdisk -l gives io errors.
You think this can work out???. Also, i do not have an extra disk and this partition is a 35GB one. Sheesh.....how worse can it get.

You've gotta use fsck -b. Don't worry about what fdisk tells you.

try using debugfs and e2fsprogs to recover the partitions. this link might be useful as well. http://e2undel.sourceforge.net/recovery-howto.html

Don't use e2fs tools on an ext3 partition. You'll get screwed. Journalling changes the way a lot of things work.
Evening Trevor,
Philip,

<snip> Disk having bad sector will give you fdisk -l information. In case if you are using HBA's or SCSI controller ( i.e. PERC 4/D ), you might get "Unable to get access to /dev/sd?". and purely 'cause of HBA's or SCSI controller.
fdisk -l only reads the gemotery information of the disk ( Which is not placed on the sector ( for data information ).

Luckily no HBA or SCSI controller. Its IDE. dmesg screams io error. And fdisk -l doesn't work but throws up io errors.
What say??.

sorry trevor, should have given this solution first.
put your hard disk into the freezer (T<0°C) for 24 hours. When you take it out it should work for at least 24 hours. That should give you enough time to copy the data off it.
Philip
PS: I'm not kidding. I've done this twice before.

Yeah it works I have tried that as well :) Just be sure that you cover the HDD well before you put it in the freezer :)
The release notes of e2fsprogs say that ext3 fs is supported for quite a few operations including replaying journal in user mode and identifing/reading superblocks on disk. but YMMV.

Philip/Vin,
There is also Granjo, a fine white wine i picked up from goa last week. You think its presence will chill up the disks and cough up some life into it..:D.

dunno about that, but I know my dad will love it. It's one of his favourites.

Here's another solution : you call a few (very few) of your friends home and make them forcibly drink the wine. That way your freezer will be empty and a HDD cooling session requires an empty freezer.
ummm... BTW, I am free tomorrow...
:D

I second Quasi's IDEA.

And I am always free when something involves fine wines!
:D
So I will keep my finger Xed for an invitation. ;-)
With regards,
Fellas,
The drinks are on me...tell me the place where we can catch up. We can have a glug-beer meet. All beers on the house but the place will have to be someone elses...:D
