mount: wrong fs type, bad option, bad superblock on /dev/hdc3


I get the above error when trying to access a HDD that used to house a SUSE install (i'm not sure how much is left of it, i resized it's partition...).

When i say
Code:
dmesg | tail
as the error goes on to reccomend, i get the answer:

Bend_request: I/O error, dev hdc, sector 176233066
ReiserFS: hdc3: warning: sh-2006: read_super_block: bread failed (dev hdc3, block 16, size 512)
end_request: I/O error, dev hdc, sector 176233178
ReiserFS: hdc3: warning: sh-2006: read_super_block: bread failed (dev hdc3, block 128, size 512)
ReiserFS: hdc3: warning: sh-2021: reiserfs_fill_super: can not find reiserfs on hdc3
end_request: I/O error, dev hdc, sector 176233066
ReiserFS: hdc3: warning: sh-2006: read_super_block: bread failed (dev hdc3, block 16, size 512)
end_request: I/O error, dev hdc, sector 176233178
ReiserFS: hdc3: warning: sh-2006: read_super_block: bread failed (dev hdc3, block 128, size 512)
ReiserFS: hdc3: warning: sh-2021: reiserfs_fill_super: can not find reiserfs on hdc3

My thinking is that this is basically saying "get a new hard drive" but i'd like to save a fair proportion of the data off this one, and ideally the functionality (even if not the data).
Any ideas? Currently trying to access it through a Knoppix live DVD, but i'm reliatively new to Linux so i don't know which rescue tool does what....
If the data's irretrievable, any ideas on how to make the hard drive useable post-format?

It's an IDE Maxtor DiamondMax 250GB. Been using as a storage drive for my Mandriva installation for a while, with no problems under Linux or Windows previously. BIOS has sketchy recognition of it - in CMOS setup it gives no info on cylinders or heads as on other drives.

Cheers!
Avi.

can you fdisk /dev/hdc -l to show what partitions are there?

fdisk /dev/hdc -l

gives

cannot open /dev/hdc

I *think* i managed to get qtparted to see it on the rescue disk earlier though. Will try that later. What results specifically would help?

Similar Problem

I am having a similar problem to what is listed above...

Here's a long story short - I reinstalled Windows 2K and it suddently started reading my hard drives (and partitions) as "parameter incorrect" and was asking me to format. Well, I decided I'd give the HDD a chance in linux to pull some data off.

I installed Mandriva 2005 and am attempting to mount a hard drive. When I attempt to mount hdc1 however I get:

"mount: wrong fs type, bad option, bad superblock on /dev/hdc1 or too many mounted file systems"

When I attempt to mount hdc2 I get:
I do not get an error as listed above, however if I attempt to ls I get "input/output error"

when I type "fdisk /dev/hdc -l"

"Device Boot Start End Blocks Id System
/dev/hdc1 1 12396 99570838+ 7 HPFS/NTFS
/dev/hdc2 12397 24792 99570870 7 HPFS/NTFS"

Is it possible to recover this data...? What confuses me is this happend to 2 new harddrives (6mo old). One is a 200gb and one is a 160gb.....

I'm in the same boat here, except i get a whole load more errors than already stated.

fdisk /dev/hdc -l gives:

knoppix@0[knoppix]$ fdisk /dev/hdc -l
Note: sector size is 2048 (not 512)

Disk /dev/hdc: 728 MB, 728190976 bytes
255 heads, 63 sectors/track, 22 cylinders
Units = cylinders of 16065 * 2048 = 32901120 bytes

Disk /dev/hdc doesn't contain a valid partition table

Now this doesnt seem quite right to me as its a 40gb hard drive (should be more like 38.... bytes)

Accepted I need a new hard drive, but i have maybe 1000 irreplaceable photos on there, which i would do anything to retrieve.

Is there much that can be done to DIY salvage or maybe get some pros in?

Hi guys,

Sounds like a few of you have corrupt partition tables.

try fsck /dev/deviceYouAreHavingProblemsWith

This will check all the things that cause problems in this area.

It will ask you lots of questions at the end of the process, In the main I would advise answering Yes to them all, unless it sounds grossly wrong.

Load up a livecd and reiserfsck

--check consistency checking (default)
--fix-fixable fix corruptions which can be fixed without
--rebuild-tree
--rebuild-sb super block checking and rebuilding if needed
(may require --rebuild-tree afterwards)
--rebuild-tree force fsck to rebuild filesystem from scratch
(takes a long time)

Should fix you up.

Short read reading journal superblock

I just tried fsck and this is what I got:

________________________________________________________________________
This is the first time that I've ever even really looked at the file system in 8 years of using Linux. I know I'm an idiot for not caring, but I do now. I've heard for years that ext3 is far better than NTFS and frankly that's always been good enough for me. So if anyone has a clue which direction to point me and can be of assistance it would be greatly appreciated. Yes this is the /home partition of a "win2k domain controler" where all of the user files are. It always bugs me when people start crying about how important the data is so I won't do it. Only that the data was important enough to me that my "win2k domain controler" is not win2k. I here by swear that I will help the next person with a problem that I know how to fix. I would have done that anyway but there it is. Thanks in advance.

Almost identical problem

Let's bump this thread a bit. This is my story:

I have 2 SATA HDDs and an old IDE HDD mounted on my computer. My /home folder and the / folder were two partitions on the IDE HDD (/dev/sdc6 and /dev/sdc7 respectively). Other files were on the other hard drives.

Today while chatting with work colleagues in Pidgin, there was a 2-second freeze, then everything started to go downhill. The keyboard stopped responding, and after a restart Grub could no longer find the partition table on sdc.

I tried a system restore using an OpenSuse 11.1 DVD (the distro currently installed), but it failed each time when running fsck on /dev/sdc6 or /dev/sdc7.

I reinstalled OpenSuse 11.1, keeping the troublesome HDD aside while resizing partitions on my other HDDs.

Here is what happens when I run fsck:
-----------------------------------------------------------------
>fsck -p /dev/sdc7
/dev/sdc7: Attempt to read block from filesystem resulted in short read while reading block 1545

/dev/sdc7: Attempt to read block from filesystem resulted in short read reading journal superblock

fsck.ext3: Attempt to read block from filesystem resulted in short read while checking ext3 journal for /dev/sdc7
------------------------------------------------------------------

And fdisk -l:
------------------------------------------------------------------
>fdisk -l /dev/sdc7

Disk /dev/sdc7: 140.9 GB, 140940140544 bytes
255 heads, 63 sectors/track, 17134 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Disk identifier: 0x00000000

Disk /dev/sdc7 doesn't contain a valid partition table

>fdisk -l /dev/sdc

Disk /dev/sdc: 163.9 GB, 163928604672 bytes
255 heads, 63 sectors/track, 19929 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Disk identifier: 0x10541054

Device Boot Start End Blocks Id System
/dev/sdc1 1 19929 160079661 f W95 Ext'd (LBA)
/dev/sdc5 1 183 1469884+ 82 Linux swap / Solaris
/dev/sdc6 184 2794 20972826 83 Linux
/dev/sdc7 2795 19929 137636856 83 Linux

------------------------------------------------------------------

I used debugfs and managed to browse around without getting any errors:

------------------------------------------------------------------
>debugfs /dev/sdc7 -w
debugfs 1.41.1 (01-Sep-2008)
debugfs: ls
debugfs: cd nikozeta
debugfs: ls
------------------------------------------------------------------

After unsuccessfully trying to mount the troublesome partition using Yast, here is what I get when I run dmesg | tail:
------------------------------------------------------------------
>dmesg | tail
EXT3-fs: error loading journal.
ata6: EH complete
sd 5:0:0:0: [sdc] 320173056 512-byte hardware sectors: (163 GB/152 GiB)
sd 5:0:0:0: [sdc] Write Protect is off
sd 5:0:0:0: [sdc] Mode Sense: 00 3a 00 00
sd 5:0:0:0: [sdc] Write cache: enabled, read cache: enabled, doesn't support DPO or FUA
sd 5:0:0:0: [sdc] 320173056 512-byte hardware sectors: (163 GB/152 GiB)
sd 5:0:0:0: [sdc] Write Protect is off

sd 5:0:0:0: [sdc] Write cache: enabled, read cache: enabled, doesn't support DPO or FUA
------------------------------------------------------------------

The similarities with the previous post should be striking. If someone can point me to a solution, I will certainly post a detailed description of how I managed to get this important data (including all my passwords!!)

Recover some of your data

I should just mention that it is entirely possible to recover the non-corrupted parts of an unmountable device formatted with ext2 or ext3. Simply start the debugfs: (use -c instead of -w if the latter doesn't work)

>debugfs -w /dev/sdc6

Then you can navigate to the folder you want to save, and use dump or rdump (recursive dump) to get the non-corrupt files to your native (and working) file system. I just recovered all the files I needed like this.

I had similar problems with my hard drive after a power trip. The partition table corrupted. I tried everything mentioned here, nothing worked. Finally it was spinrite that saved me. It managed to fix everything back to normal.

at first fsck was not working.

then i tried "initialise /dev/sdb1 1900000" in debugfs for my pendrive and then did fsck command

fsck asked loads of question but fixed it.
