Ubuntu Installation :: Bad Superblock - Wrong FS Type

Jan 4, 2010

I cannot for the life of me get my HD working again. I tried following all the various remedies I could find but to no avail.

Code:
ubuntu@ubuntu:~$ sudo e2fsck -f /dev/sda1
e2fsck 1.41.4 (27-Jan-2009)
e2fsck: Attempt to read block from filesystem resulted in short read while trying to open /dev/sda1
Could this be a zero-length partition?

Code:
ubuntu@ubuntu:~$ sudo dumpe2fs -f /dev/sda1 | grep -i superblock
dumpe2fs 1.41.4 (27-Jan-2009)
dumpe2fs: Attempt to read block from filesystem resulted in short read while trying to open /dev/sda1
Couldn't find valid filesystem superblock.

It goes on and one like this. I'm stuck using the LiveCD for now (Jaunty) so I have some limitations.

Server :: Mounting Drive Bad Superblock Error Wrong Fs Type, Bad Option, Bad Superblock On /dev/sda1?

Jun 16, 2010

I have a x64 OpenSUSE server with two hard drivers installed. The first one is used for the / and /home partitions and the other is for backups. Ironically enough it is the backup hard drive I am having trouble with. I was having trouble writting to the drive and unmounted it to preform a fchsk, however now when ever I try to mount it I get the following error:

mount: wrong fs type, bad option, bad superblock on /dev/sda1,
missing codepage or helper program, or other error
In some cases useful info is found in syslog - try
dmesg | tail or so

Does anyone know who I can repair the drive and retrive data?

Fedora Hardware :: Hard Drives Keep Crashing - Mount: Wrong Fs Type, Bad Option, Bad Superblock

Aug 26, 2010

I am writing as yesterday, my fourth hard drive within 2 years crashed. Is that normal? One was crashing 2 years ago, one in winter 2009 and 2 just within 2 weeks. What can be the reason for so many crashes? I heard maybe the power supply? How can I find out if that's broken? The voltages at least in BIOS seem normal. The SATA controller? How do I know if its broken? Can I just but one PCI-E card with SATA adapters? Is it the motherboard? Theres not much more in my computer... As well, its wired that my good-old 160 GB drive never crashed, only constantly the bigger ones. Here some typical error code from mount and dmesg:

Code: mount: wrong fs type, bad option, bad superblock on /dev/sdb2, missing codepage or helper program, or other error

ata2.00: status: { DRDY ERR }

OpenSUSE Install :: Error Message Was 'bad Magic Number, Corrupt Superblock' With A Suggested Command To Try Another Superblock?

May 14, 2011

After several crashes during videos it seemed like a good idea to fsck root. Downloaded the latest systemrescuecd and ran it at boot. The error message was 'bad magic number, corrupt superblock' with a suggested command to try another superblock. That failed with the same message. Tried tune2fs to force fsck at boot and got the same message. The drive is less than 6 months old and the installed system is working more or less ok. The command I used was 'fsck.ext4 /dev/sdc2'. What am I doing wrong?

Software :: Upgrade To 10.04 - Wrong FS Type

Jun 19, 2010

Just upgraded from 9.10 to 10.04 and cannot mount one of my partitions. It is encrypted / decrypted in the following fashion:
Code:
# dd if=/dev/random bs=4k count=1 | gpg -a --cipher-algo AES256 -c - > /mnt/usb/keys/fs.gpg
# gpg -q -o - /mnt/usb/keys/fs.gpg | cryptsetup -v -h sha512 -c aes-xts-plain -s 512 create crypto /dev/md1
# mkfs.ext4 /dev/mapper/crypto
# mount /dev/mapper/crypto /crypto

It has been this way for a long time, survived several release upgrades. Now when I decrypt it, I have to use gpg in one command to decrypt the key to a file, then use cat in a second command to pipe to cryptsetup, as such:
Code:
# gpg -q /mnt/usb/keys/fs.gpg
# cat /mnt/usb/keys/fs | cryptsetup -v -h sha512 -c aes-xts-plain -s 512 create crypto /dev/md1

However, I can no longer mount the device:
Code:
# mount /dev/mapper/crypto /store/
mount: you must specify the filesystem type

This is how it's always been mounted. Well I know it's ext4, so I supplied that and was greeted with:
Code:
# mount -t ext4 /dev/mapper/crypto /store/
mount: wrong fs type, bad option, bad superblock on /dev/mapper/crypto, missing codepage or helper program, or other error
In some cases useful info is found in syslog - try
dmesg | tail or so

The only item in dmesg is:
Code:
[78.212761] EXT4-fs (dm-0): VFS: Can't find ext4 filesystem

Ubuntu :: Bin Folder Deleted - Wrong FS Type Errors

May 29, 2010

I made the unfortunate mistake of doing this (sudo rm -r /bin) instead of (sudo rm -r bin) in the folder I was in..I'm trying to copy my data over from my Karmic system using mount, but I'm unable to mount. When I try to mount I get errors of an wrong fs type..

I've done fdisk -l & I get this:
/dev/sda1 * 1 37599 302013936 83 Linux

What the heck filesystem is Linux? Is that like ext3 or something? I don't know. Here is what I'm trying to run:
mount -t ??? /dev/sda1 /media/disk -o force

Also, besides that. If there a way I can fix my OS without having to do a reinstall? Or at least is there a way can backup my files? I have a 1tb external so that's not the issue.

Software :: (DVD Error) Mount - Wrong FS Type

Jul 14, 2011

A colleague had troubles with a DVD that contains valuable data, no further backup available. The DVD won't run and I am trying to fix it. Have been playing around on Mac, Windows and Linux successively.

On Mac
Mac shows this message in Toast Titanium 10:
but Finder keeps telling it is an empty disc, no way to get to the files.

On Windows
Windows 7 in VMWare is not of any help.

On Linux
Just installed Ubuntu 11.04 (in VMWare) and did some checks using info on this forum. When trying to mount the disc, this is the error message. Then I used fdisk on the volume (/dev/sr0) and tried fsck. I downloaded UDFTools but cannot find any repair option like udffsck as described in this thread by the last author.

I am running out of inspiration... there are clearly data on the disc, which can be seen by just looking at its surface, but also the info on Mac. However, there might be some bad sector size in the partition table which renders it unreadable. How to recover these data?

Slackware :: Kernel Tries To Mount Wrong FS Type?

Aug 13, 2010

I just installed Slackware 13.1 x86 on a new laptop (you probably remember me from my audio post). I am having one other issue. My root file system is formatted as EXT4. When my computer boots, it tries to mount it as EXT3 then EXT2, fails both types and then tries EXT4. Here are the messages.

Code:
EXT3-fs (sda2): error: couldn't mount because of unsupported optional features (240)
EXT2-fs (sda2): error: couldn't mount because of unsupported optional features (240)
EXT4-fs (sda2): mounted filesystem with ordered data mode
So, eventually / is mounted correctly, but I think this is slowing down my boot time. Does anyone know how to fix this.

General :: SD Card Mount - Error "wrong Fs Type, Bad Option"

Apr 12, 2010

I am trying to make a copy of the SD card that my TS-7800 SBC boots from. When I plug the SD into my opensuse pc I get this error. Error mounting: mount exited with exit code 32: mount: wrong fs type, bad option, bad superblock on /dev/sdb4, missing codepage or helper program, or other error In some cases useful info is found in syslog - try dmesg | tail or so There are four partitions on this card and I can only access one of them.

dmesg | tail gives me this

[894.422497] EXT2-fs warning: mounting unchecked fs, running e2fsck is recommended

when I do e2fsck -p /dev/sdb4 I get

e2fsck: Bad magic number in super-block while trying to open /dev/sdb4 /dev/sdb4: The superblock could not be read or does not describe a correct ext2 file system. 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> I was hoping I could just plug in both cards and do this dd if=/dev/sdb of=/dev/sdc to copy everything and have a back up SD card.

CentOS 5 Hardware :: Receiving "wrong File System Type" Messages?

Feb 9, 2010

I tried to post this then couldn't find it anywhere, so I will try again. I am wondering if there is a way to determine what file system type was put on a volume when the file system was made? I have a MD0 device that wouldn't mount. I was receiving "wrong file system type" messages.

I tried df but this only works with mounted file systems correct? I am looking for a command to run on a drive/volume that is not mounted so I can figure out what file system is on it.

This time I was able to: mount /dev/md0 /mnt/storage without and entry in the fstab file. I then just entered mount and it displayed the file system as jfs.

Is there another way to determine the file system type?

Ubuntu Installation :: Superblock Error In Gparted - Can't Run Dumbe2fs - E2fsck

Mar 8, 2011

I have Ubuntu 10.10 installed (installed xubuntu on top and that is what I run but should not be an issue) on a laptop and it runs fine but I am giving it to my daughter so I wanted to install windows as well, and dual boot, so she could play a couple of games that she has. When I booted with gparted cd it shows the information icon beside my partition (have 2 one swap sda1 and one for ubuntu sda2) and everything I attempt to do tells me the superblock and all backups are bad. I am not sure how this can be since the system boots and runs fine.

In gparted I can't run dumbe2fs or e2fsck without getting the error but when I do dumpe2fs in the system it seems fine. I am pretty sure I used ext2 or ext3 as a filesytem as it is an older laptop so ext2 is what I usually run with. Maybe I just let ubuntu install whatever it wanted this time, I can't remember for sure which I chose during this install. have been backing up all the data to move it off anyway so reinstalling won't be a big issue. I had checked out how to reinstall grub2 after doing the windows install so thought I was all prepared but apparently I was not that prepared.

Ubuntu :: Changing File System Type To Another Filesystem Type - Does It Effect On Data?

Feb 4, 2011

In my system around 73gb(pc-desktop) i have,1 primary partition(windows)-25gb, 1-extended partition(remaining gb) 3 logical partitions were there in (under) extended partition in one of the logical partition is d:drive. in my hard disk d: drive is -/dev/sda5

previosly i was fat -file system , (d:drive-/dev/sda5), i remember i changed the d: drive(d:drive-/dev/sda5) file system to ext4file system ,with following command using terminal

After doing(changing the file system)this one ,i couldnt see the d:drive data

By doing that

1q) Did i reformatted the partition? i think the new filesystem(ext4) has no knowledge of the data that was on it when it had a FAT filesystem.

2q) How to do undo operation,i tried to change the filesystem type to fat/ntfs in terminal using command --sudo mkfs -t FAT /dev/sda5.

Result:its showing text message-'mkfs.FAT: No such file or directory'(not in single quote)

I had very imp data in d:drive

Ubuntu Installation :: Installation Migration Attempt Gone Wrong

Feb 27, 2011

I installed Ubuntu 10.04 (32 bit version) a few months ago on a system with two IDE drives (cable select configuration). The primary drive (/dev/sda) is 40GB and the secondary drive (/dev/sdb) is 80GB. I created all of my partitions on the primary drive and left the secondary drive unconfigured. After a month or so I noticed that two of my partitions had quickly reached 50% capacity, as I had just taken a guess at an appropriate partition size when I first installed Ubuntu.

Since I had a larger unused drive already in place, I decided to migrate my installation from the smaller drive to the larger drive, but sizing the partitions in question more appropriately (i.e., much larger). I assumed that I could install Ubuntu on the bigger drive with larger partitions, byte-for-byte copy all my existing partitions from the old disk to the new one, edit /etc/fstab, reboot, and GBTW. Naturally that didn't work as I expected.

Here's what I did: Carefully logged my existing partitions on /dev/sda and their mount points Used a live CD to install the same version of Ubuntu on the larger drive (/dev/sdb), using its partition tool to generously size my partitions. I carefully logged the new partitions and their mount points. For each partition on /dev/sda (except for /boot and swap), I used dd to create a gzip'd image and stored all of those images on a backup drive.

I then used dd to complete the task of migrating all of these partitions (again, all but /boot and swap) to their respective partitions on /dev/sdb.

Ran blkid to see all of my partitions. I noticed that some of the UUIDs existed on both drives. I thought "hmmm...that's weird" and moved on.

Mounted my new root partition (/dev/sdb6) on a contrived mount point.

Edited /etc/fstab (after backing it up) and carefully replaced all the old UUIDs with their respective counterparts on my new drive. Also replaced the device reference for /boot with its respective counterpart.
Crossed fingers. Rebooted. Got some warnings about missing UUIDs.

After the system completely booted, I used the graphical disk utility and saw that the system mounted some partitions from /dev/sda and others from /dev/sdb. Not good.

Here are the steps I took since lurking here:

It seems my installation still has an identity crisis. What steps should I take from here to force my Ubuntu installation to only use my partitions on /dev/sdb?

Was there an easier way for me to migrate my installation to a new drive?
