Debian :: USB Drive Corrupted - Cannot Read Superblock
Mar 16, 2011
I have a removable USB pen drive, that all of a sudden, when it got 99% used, stopped working. When I try to mount it (manually) I get "can't read superblock". I know there is a ton about this on Google and I've read a lot of them, but most seem to be about formatting a drive, or fiddling in fstab. I'm trying to run fsck on it, and it finds errors, (among them: two FAT-tables?) but then it just freezes, and CPU goes to 100 % and I let it be like that for 4 minutes, before aborting. Scandisk in windows is rubbish (fails to start), and running "chkdsk /f F:", in windows, results in nothing, the shell crashes immediately. Is it normal for fsck to get stuck and just chew up CPU? It does not seem to be reading from the drive, according to conky. Also, is it possible to run fsck as normal user, (at my work)?

I removed a hard drive from a failed Buffalo LinkStation NAS. The drive was 1TB and formatted in XFS. I installed Debian Linux on my Mac using Virtual Box just so I could get to the files.
When plugin the drive (via USB) two volumes show up, but there's another that I can't seem to open (and may have all of the shared files I need). It's the largest volume (over 900 MB).
I keep reading to run xfs_repair, but when I type that in the terminal, I am given "command not found". I am not sure how to use it.
Also when I try to open the volume I am given "can't open superblock" error.
I am not too familiar with using Linux and ma just trying to get to my files.

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?

i used to have ubuntu 9.i decided to move to sabayon so i used the live cd to install it ,resize the ubuntu partition and use the remaining space for sabayon.while the resizing procedure i got an error(i dont have a copy of the error log file but i know it has something to do with an anaconda process).i aborted the installation and the result was an filesystem that couldnt be mounted.when i try to mount the hdd i get this:
Code: Error mounting: mount: wrong fs type, bad option, bad superblock on /dev/sdb1,
missing codepage or helper program, or other error
In some cases useful info is found in syslog - try
dmesg | tail or so and this is what i get from fsck: Code: $ sudo fsck -f /dev/sdb1

I have a problem in my ubuntu 10.01 that it can't load a drive/volume in ubuntu. When I tried, it said: "Unable to mount location Error mounting: mount: /dev/sda1: can't read superblock". And when I boot my pc with 'Windows', it said : "UNMOUNTABLE_BOOT_VOLUME" under a blue screen. What can I do to solve this problem?

I am newer to Slackware but not to Linux. I am having the hardest time trying to get my CDROM to mount for me so that I can play audio cd;s and the like. I can see that the system knows that my CDROM drive is there and that it works because I installed Slackware 13 from my CDROM drive as /dev/hdc. Now when I put in a cd nothing happens? I have googled away and searched this forum quite a bit before posting this but I have tried almost everything I can think of and what others have mentioned. I have screenshots to show you what I mean. When I try to run the command:
mount /dev/cdrom /mnt/cdrom
I get it as mounting as read only and it says can't read superblock? Now that is fro my slave IDE CDROM on top as hdd. I have tried before to mount it as /dev/hdc but to no avail. I know both CD drives work just fine because I used them to install the system. I am going to put the screenshots below so maybe someone can help me! Also I can eject the top CD drive with the command code...

I am unable to boot my server and it is erroring with the message "Kernel panic - not syncing: Attempted to kill init!". Here are the details:
I have a brand new Dell PowerEdge T110 server with Quad-Core Xeon CPU and 2GB 1333MHz RAM. I have installed a hard disk (SATA, 7.2rpm) on this machine that I removed from another Dell PowerEdge T100 server with Dual-Core Xeon CPU that was running software RAID 1.
Now when I boot the new T110 server, it displays the following error messages code...
I am running CentOs v5.5 x86-64. If I put the hard disk back into T100, it boots fine. I do not know why it is not working with T110 server.

I want to populate an array of string by files exists in directory on mounting of file system. I got an entry point for file system mount. I can use either do_mount function or fill_superblock function. But I am not clear about how to call readdir from there itself. I need inputs for calling readdir from fill_superblock function.

This problem has arrived again.......I tried the same solution but didn't work out...the problem is described below.
I use Ubuntu 9.10 .
I did this in Ubuntu 9.10 live CD.
quote from terminal :-
ubuntu@ubuntu:~$ sudo mkdir /win
ubuntu@ubuntu:~$ sudo mount /dev/sda5 /win
ubuntu@ubuntu:~$ sudo mkdir /vdisk
ubuntu@ubuntu:~$ sudo mount -o loop /win/ubuntu/disks/root.disk /vdisk
[Code]....
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>
ubuntu@ubuntu:~$ "
> ^C
ubuntu@ubuntu:~$
^^ quote ends.

I got a CentOS server + KDE from a server (which I had no contact until now), he had 2 HD's one for the system and another for files.
I brought the HD system home to try to make it run on a virual machine (VMware) so I can do some testing before you put in practice.
But already converted the VMware HD to the system, it tries to start but it shows some errors and in a message "kernel panic - not syncing: attemped to kill init"
I think the drivers are correct, has edited the file "/ etc / modprobe.conf" edited these entries equal to another I installed CentOS on VMware.
alias scsi_hostadapter mptbase
alias scsi_hostadapter1 mptspi
ata_piix alias scsi_hostadapter2
Look at the picture attached the full error.

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?

I'm trying to 'upgrade' my 500gb drive to a bigger 1tb. I thought it would be as easy as using dd from the smaller to the larger then swapping them. However, after using dd, although the partitions seem to be there on the 1tb drive, they all have a bad superblock and can't be mounted.

I have an mdadm linear array of 4 500GB drives. One of them had a few bad sectors, so I've dd'ed it to a new one (conv=noerror), and tried to start my array. Mdadm refuses, saying, "mdadm: /dev/md4 assembled from 3 drives - not enough to start the array."I had diffed different samples from different positions on the source and the mirror drive and confirmed they were identical. Checking the superblocks confirms three old drives still having their superblocks as expected, while the newly mirrored one has,
daniel@lnxsrv:~$ sudo mdadm --misc --examine /dev/sdf1
mdadm: No md superblock detected on /dev/sdf1.
- and,
daniel@lnxsrv:~$ sudo blkid /dev/sdf1
[code]....
As before. The mirror apparently has no uuid, but the original does. To confirm my sanity, I did,
daniel@lnxsrv:~$ sudo dd bs=1M count=50 if=/dev/sdc of=./sdc && sudo dd bs=1M count=50 if=/dev/sdd of=./sdd && sudo diff -s sdc sdd
50+0 records in
[code]...
How can the uuid not be the same when bit-for-bit from the very first byte of the drive, covering MFT etc., these two drives are identical according to diff?

Trying to go through some old hard drives I'd saved from a Mac we tossed years ago. Using a Sabrent USB adapter (USB-DSC9) I connected it to the Debian box and it mounts as /media. Here's the weird thing: although I can read all the random stuff, the directory with all my actual documents shows up as "you do not have the permissions necessary to view the contents". When I try to fix this with chmod, it tells me that the drive is read-only. Grr.
How do I mount the drive so that it's not read-only?

I've been running Ubuntu 10.04 for a while now on my 500 gb external hard drive, and for the most part I've had little to no problems I couldn't fix with a little common sense. However, recently my computer was taking an unusually long time to boot up, so I restarted, which normally works just fine, but just as I restarted the system had begun to boot. Now when I boot I get the following:
Code:
mount: mounting /dev on /root/dev failed: No such file or directory
mount: mounting /sys on /root/sys failed: No such file or directory
mount: mounting /proc on /root/proc failed: No such file or directory
Target filesystem doesn't have /sbin/init.
[Code]....
I haven't tried an Ubuntu LiveCD, because I lost mine (making a new one is difficult with our current internet connection) and I feel I would get the same results. At the very least, I would like to be able to get all my music, videos, etc. off the drive, but I would prefer being able to fix it completely so as not to have to buy a new one.

This is a USB shared drive, with an ext3 partition. The partition is located at /dev/sdb1. I use Samba to share /media/tiga1000/samba/public, and everyone on the network can add/delete files to it. Specifically, this is our media drive, and we upload a lot of pictures to it, since me and my sister are amateur photographers. Under /public/images/camera_pictures/2010, I have 3 directories. 01_january, 02_february, and 03_march. The directory that has been corrupted is 03_march, and when I say corrupted, I mean that I cannot open it. It acts as a unknown file type that can't be opened.
Here is the file properties of it:
Code:
drsmall@mycroft:/media/tiga1000/samba/public/images/camera_pictures/2010$ ls -lah
total 960K
drwxr-xr-x 4 nobody nogroup 4.0K 2010-03-11 21:22 .
drwxr-xr-x 5 nobody nogroup 4.0K 2010-02-18 20:19 ..
drwxr-xr-x 14 nobody nogroup 4.0K 2010-01-31 11:57 01_january
drwxr-xr-x 10 nobody nogroup 4.0K 2010-02-23 15:47 02_february
-r--r--r-- 1 nobody nogroup 938K 2010-03-11 15:46 03_march
How I should go about recovering it. Somehow it lost it's directory switch. Should I unmount the drive and run fsck on it? I would like to be able to recover these images, if it is at least possible!

I unwisely lent my USB stick to a friend who desperately needed to copy some files between home and work. When she returned it, I plugged it in and found the files could not be read (I have a few things on there she was told not to delete). It appears to have become corrupted- can't say how it happened as I wasn't with her, though she was successful in using it (windows machines of some variety).Output of ls is a succession of 'ls:cannot access <garbage> Input/output error' with the odd 'No such file or directory' interspersed between them.
I'd like to recover my files if possible, a few are latest versions and hence the backups aren't up to date. I'm using an Acer Aspire one with the supplied Linpus linux (based on fedora 8), also have access to my old laptop and desktop with older versions of fedora on them.On the Aspire one, kernel is 2.6.23.9lw.The usb drive is a 16GB Super-Talent (really small one) which mounts as /media/disk
I've read that using e2fsck on a mounted drive is a bad idea, so am looking for suggestions. I just want to recover the files (and am hoping I can then format the disk and make it useable again).

The computer that I have Ubuntu/Karmic just recently installed on, has 2 hard drives. Primary is Ubuntu, secondary is win95b. After the Karmic installation (which went perfectly), I now find that when I boot to the secondary drive, the MBR for win95b is reporting it is corrupted. I can use win95b, BUT it runs in dos compatability mode, and there are no CD drives showing, despite the fact that BIOS reports 2 cd drives. Can GParted fix the corrupted MBR on the win95b hard drive?

I wanted to check the first sector of my USB stick, and so I issued:dd -if=/dev/sda -bs=1024 -count=1It showed me all the weird characters from the data, then after it executed my bash prompt became corrupted with the same kind of characters! Also, everything I typed was like that. (see the picture)Luckly, it was just that tty that became like that.How can I fix the fonts after something like that happens, and how to prevent it from happening whenever I use dd again?

i have got an Debian Lenny NAS with 7x1,5TB of a Softwareraid5. Kernel Version is 2.6.32. The Raid ist mountet in /media/raid5. The System ist on a seperate disk and work fine. After i tested the performance of the raid with:
dd if=/dev/zero of=/dev/md0 bs=1G count=1 oflag=direct
Since i had done this i cant find any Data on /media/raid5. cat /proc/mdstat and mdadm --detail /dev/md0 looks fine. All UUID's are good. But: The SuperBlock is unreadable and the partition table was not found. mke2fs -n /dev/md0 shows some Backup of the Superblock , but i cant repair it with fsck.ext4: Illegal inode number on /dev/md0.

I was working on my RHEL 5.2 workstation yesterday when the OS became flakey. first I noticed that some software that I had running was outputting and error that it was unable to write to log file because permission was denied - I've never seen this output before- it would have been writing to my home dir running under my user name. From an open terminal, i did "ls -al" and saw that many of the permissions the files in my home dir were listed as "????????" some were still "rwxrwxrwx", as well, many files were highlighted in the colors set for links and root privileges.
I tried to start a new terminal, and it failed. then Gnome crashed. When I reset the Machine, I got through grub, and into the startup, and after finding the Volumes, the startup failed with a Kernel panic:
giving several errors- like:
I dont have much experiencie with this stuff, but it looks obvious that somethig like the MBR or wherever the partion information is stored might have been corrupted.
What I dont understand is why I can get into GRUB (its a dual boot Windows Vista, RHEL machine). I'm guessing that this means its not a mechanical problem, because I can get RHEL to begin to boot which i think is failing somewhere around the /etc/rc.d/re.sysinit script, and also can get Vista to bring up the inital windows screen and a mouse pointer on spanning both of my screens which i think means that it must have at least loaded my ati drivers for my dual head radeon 4850. windows hangs there however.
I've tried the RHEL 5.2 rescue disc, and it doesn't recognize any Linux partitions.
I ran the system diagnostics out of the dell bios and it came back with a failed HDD : Error code 0142, but from digging around a bit I've found that this is a very broad diagnosis.
My concern over it being a mechanical problem is that I'm not sure that I want to try to run any further diagnostics, or any of the disk utility programs that i've seen listed here on linuxquestions, as it might damage it further, and there is some data that i would really like to get off this disk.

I am trying to install an ARM version of Ubuntu onto an SD card for a BeagleBoard from a .img file downloaded from http://releases.ubuntu.com/lucid/. I have tried several files of .img and .raw downloaded from several places. I am using 'dd' on a PC running Ubuntu 10.0.4. My question doesn't relate to the BeagleBoard at all since I never get that far. The files for Angstrom that I copy directly onto a formatted SD card boot up fine on the BeagleBoard, but I need Ubuntu on there and can't do it with these image files. The command I use is:
sudo dd if=<the downloaded file> of=/dev/sdb1 After it asks the root password, it chugs along for some time and then gives what appears to be a successful response like the following. (This time it was for the Maverick version of Ubuntu in a .raw file):
leiphasw@dell-linux:~/Downloads/ArmMaverickUbuntu$ sudo dd if=maverick-preinstalled-netbook-armel+omap.raw of=/dev/sdb1

I bought an 8GB flash drive because my D drive doesn't read DVDs. Anyway, my goal is to install Linux ubuntu and have it be my OS (replacing Windows XP). Last night I went to the Ubuntu homepage and downloaded the Ubuntu desktop edition 32-bit and put it on my flash drive. I followed the instructions on how to open and run it, but I was never asked about whether I want Linux to run side by side with Windows or if I want it to replace Windows. It downloaded the whole program, my computer restarted and then (on a black screen) it asked if I wanted to use Windows XP Home Edition or Linux Ubuntu. It's really frustrating because it took a while to download and install it in the first place AND to top that off, when I tried to use Ubuntu it went to a black screen and at the top said that there was an error. So I uninstalled all the ubuntu program and software and now I have a clean slate and want to try this again. I am a complete n00b. Could someone please walk me through how I can go about downloading (w/ links plz), installing and making ubuntu my ONLY OS on my computer via a flash drive? I'm desperate and I don't want to go through all of that and make the same mistake again!
