Hardware :: Corrupted USB Flash Drive Needs Fixing
Jan 7, 2010
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).

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
4090632+0 records in
4090632+0 records out
2094403584 bytes (2.1 GB) copied, 167.38 s, 12.5 MB/s

I have been using Ubuntu Live CD to get forensic (can't be modified in any way) images off of drives, but on dirty filesystems it does some type of fix on dirty Windows filesystems.
It has the message: File system wasn't safely closed on Windows fixing
How do I turn that off?
I create my own live CD, so I can modify what ever. Where is it? Initrd?

I just installed Ubuntu 10.04 LTS on an external hard drive (USB connected) and I can no longer boot my Windows XP(SP3) from my internal C Drive. Grub gives me the list of boot choices, but when I choose the C drive, I just get these error messages:
GEOM ERROR
For Realtek RTL8139(X)/8130/810X PCI fast ethernet controller v2.13 (020326)
Client MAC ADDR: 00 13 D3 07 FD F5 GUID: FFFFFFFF-FFFF-FFFF-FFFF-FFFFFFFFFFFF
PXE-E53: No boot filename received
PXE-NOF: Exiting PXE ROM
(The version of Grub is 1.98-lubuntu5). I don't have a Windows System CD to boot from, but is there something I can do from within Ubuntu itself?

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.

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)?

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 made a persistent install of Ubuntu on a flash drive. I made changes to that installation. The software (Unetboontin) sets this all up. I think it partitions it for you. How do I image that flash drive to another flash drive?

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 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'm COMPLETELY new to linux. I"m running Ubuntu 9.10 and TRYING to install Devede. I have tried the Terminal, Synaptic Manger, and the Add/Remove and still keep getting this same error. I'm running a regular 32 bit Pentium 3 process to test if I like Linux or not. this is what it says: E: /var/cache/apt/archives/libavcodec-extra-52_4%3a0.5+svn20090706-2ubuntu3_i386.deb: corrupted filesystem tarfile - corrupted package archive this is not a DUAL boot computer either.

Back in Febuary, my wife bought a Toshiba Satilite from Wal-Mart and a few days ago the hard drive got toasted. So now I'm using an 8gig usb drive as the boot drive. I also have 2 other flash drives for downloads and such but overall I am very pleased.
I'm running 11.04 32 bit and was wandering if 64 bit made a difference. I've got 4 gigs of ddr3. It's slow to boot, but once it's running, it's faster then Windows 7. Very nice.
Is there anything I should chage, use, since I'm running it off a flash drive??
I have 3 seperat drives, 2 x 16 gigs and an 8 gig, and was wandering which one would be best for booting off of? What do I look for??
Here's what I got:
00:00.0 Host bridge: Advanced Micro Devices [AMD] RS880 Host Bridge
00:01.0 PCI bridge: Toshiba America Info Systems Device 9602
00:06.0 PCI bridge: Advanced Micro Devices [AMD] RS780 PCI to PCI bridge (PCIE port 2)

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!

I have a Transcend 4GB USB flash drive that suddenly stopped working. However, when I insert it into the USB slot, the light on the drive glows, but I'm unable to mount the drive, neither does ubuntu detect it.I disconnected the flash drive, and then run `dmesg | tail`. The result was this :
[ 623.940610] scsi7 : SCSI emulation for USB Mass Storage devices
[ 623.940928] usb-storage: device found at 6
[ 623.940931] usb-storage: waiting for device to settle before scanning

I wanted to upgrade my Fedora 9 laptop to Fedora 10. I executed this:
Code:
yum -y install preupgrade
preupgrade
It downloaded 1.1G of RPMs and asked me to reboot.Now when I boot, I am prompted for my pass phrase to unencrypt my /home partition on SDA4, but it can't be mounted. Same when I boot from a CD. Is there anything I can do to fix my encrypted drive? Is there a chance I'm just missing a driver? Has anyone else upgraded with preupgrade and an encrypted drive?

Ubuntu Breezy 5.10 (don't suggest an upgrade - it works!) I'm trying to setup a script which updates some software on the hard drive from a directory on a USB Flash drive.After I've plugged in the USB drive and seen it recognised by automount:
Code:
ls -l /vol/USBDISKB
OK - shows me the directory and files.
Code:
#!/bin/bash
if [ -d /vol/USBDISKB ]; then
echo "Found USB drive"
else

if there was a program where a flash drive can be used as a cd. The reason I asked is I used cd-writing programs (Brasero, k3b, etc) for music cds to rip into lossless formats (AAC and FLAC), and it sometimes does not come out right from ripping. And thought writing to the flash drive would get rid of those little errors in the songs since there are no moving parts..

I would like to back up my flash drive in case it gets lost or damaged.the flash drive is bootable with ext2 and a fat partition.the drive is on /dev/sdb1.I think the dd command would back everything up and when restored to a different flash drive everything would boot fine and be as before.I was wondering wow should I use this command to backup and restore or if there is a better option.

My USB flash drive has stopped working with Ubuntu.
Normally when I remove it I unmount it first, but the last time I just unplugged it. After I unplugged it, it started not working.
When I put it in a windows machine, it shows up as drive E: but says "no disk" when I try to access it.
In my Ubuntu machine I can see it as USBDrive under Places > Computer, but it's unmounted. When I click mount nothing happens.

I'm running Xubuntu 9.10 on an older machine. I've got a flash drive (called "TF_FLASH") plugged into a USB hub. I am using simplebackup to backup my documents (I'm writing my thesis and that is really the only important thing on this computer).
The problem I am having is this: simplebackup will run and backup my files once or twice (I have it set up to go overnight). After that, though, the name of the flash drive changes (from "TF_FLASH" to "TF_FLASH_" - note the extra underscore at the end). So, simplebackup cannot find the drive. If I go into the settings of simplebackup and change the backup destination to "TF_FLASH_" it will work once or twice, but the drive will change to "TF_FLASH__" - again an additional underscore.
I don't know if the name change is being caused by Xubuntu, simplebackup, or some other method. The USB hub is a cheap one, but I don't think that's the problem (my mouse is plugged in and continues to function, etc.).
