Ubuntu Installation :: Mount Exited With Code 12 - Failed To Read Last Sector

Mar 20, 2011

I am a beginner in ubuntu and only recently did i install Ubuntu 10.10 using Wubi. I am dual booting along with Windows 7 64bit. Before I got to know of Wubi, I created a free 20GB partition for installing linux. But since it was of no use, I decided to extend another partition adding this 20GB space. The problem now is that I am getting the following error while trying to access the partition.

"Error mounting: mount exited with exit code 12: Failed to read last sector (605949951): Invalid argument
HINTS: Either the volume is a RAID/LDM but it wasn't setup yet,
or it was not setup correctly (e.g. by not using mdadm --build ...),
or a wrong device is tried to be mounted,
or the partition table is corrupt (partition is smaller than NTFS),
or the NTFS boot sector is corrupt (NTFS size is not valid).
Failed to mount '/dev/sda5': Invalid argument
The device '/dev/sda5' doesn't seem to have a valid NTFS.
Maybe the wrong device is used? Or the whole disk instead of a
partition (e.g. /dev/sda, not /dev/sda1)? Or the other way around?"

These are the results after running sudo fdisk -l /dev/sda:

Hardware :: Error Mounting - Failed To Read Last Sector (3907027119): Invalid Argument

Sep 7, 2010

I'm trying to mount my new Western Digital Elements 2tb hard drive, but every time I try to plug it into the computer I get this error message:

Quote:

Error mounting: mount exited with exit code 12: Failed to read last sector (3907027119): Invalid argument

[code].....

But when I tried opening the hard drive from nautilus I still got the same error message as above (no other volumes was connected at the time). I've also tried opening and watching it in GParted, and I can see it there as a volume that's not allocated. When I tried to allocate the hard it I got the message that it had no partition table. And that I cold make one. I tried and Ubuntu suggested to make a MS-DOS partition table for it. But there I got a little scared as I've not done this before. The external hard drive is brand new and was brought today. And I don't have the possibility to test it with Windows or Mac as I'm using Linux only on my machines.

Hardware :: SMARTD Reported Disk Sector Read Error

Oct 27, 2010

2 months ago, I built a dedicated backup server using 4 2TB SATA drives for software RAID5 (6TB total). A few days ago, smartd sent out mail saying it found an unreadable sector on one of the drives. I ran selftest using smartctl and the error persisted. So far, neither software RAID nor ext4fs running on top of the RAID volume have reported errors.

MOST OPTIMISTIC: It is normal to have a few bad sectors among billions. Software RAID takes care of alternatives. Keep using the system until RAID spits a more serious warning in the future.

MOST PESSIMISTIC: It is a really bad sign to lead a disaster. No good disk drive should have bad sectors especially when it is only 2 months old. The error is simply not detected by software RAID and ext4. Replace the drive immediately and return the bad drive to the supplier.

General :: Cannot Read / Write SD Card After Improper Format (sector Size 0) - Fix It?

Jun 12, 2011

I was attempting to reformat a 16GB MicroSD card in my camera when the battery died mid-way. After that, any time I try to read the card in my camera, it gives me a "Card Error" and does not allow me to reformat it in my camera.

So, I thought I would plug the camera in to the laptop with it set to host the card as media when plugged in as USB, in an attempt to fix the formatting issue.

However, when I plug it in to my linux machine, it does not register as a device (e.g., /dev/sda) due to some errors, therefore I cannot reformat it. Essentially, I think I need to fix the partition table but I'm not sure how to when it doesn't register as a device. code...

Ubuntu :: Fatsort - Sort_fs: Device Or Resource Busy - Cannot Read Boot Sector Or Headers

Feb 14, 2011

I have an audio recorder that doubles as a music player. It can play WAV files. So I put in some WAV files and they are out of order, even if they are named numerically. Read somewhere about a little CLI software called fatsort so I installed. The device is located at /dev/sdc. So naturally I write fatsort /dev/sdc, it says something about permission. So sudo fatsort /dev/sdc. Thing is, it says:

Code: sort_fs: Device or resource busy! If I "eject" it (unmount) then it says something about cannot read boot sector or headers. On Windows there is FAT Sorter. It does not work in WINE. So every time I put something in, I have to get to a Windows computer to sort it. It seems like fatsort is the only program that sorts FAT systems in Ubuntu/Linux.

General :: Why Can The BIOS Only Read And Execute Code And Data From Only Cylinder 0, Track 0 And Sector 1

Ubuntu Installation :: Failed Upgrade: Partition Locked As Read-only?

Nov 26, 2010

I was updating from 10.04 to 10.10 earlier today when my laptop shutoff in the middle. I fixed a grub error by reinstalling it with a live-cd, and found out I had a "kernel panic-not syncing: VFS: unable to mount root fs on" waiting for me. I booted an alternative kernel and tried fixing things from there, but got "general error mounting filesystem". So, I tried a live-cd and when I mount the partition, it is read-only. I tried running fcsk to no availThe only thing I could find helpful was this."It's probably because your filesystem has suffered a failure - it is configured by default (in /etc/fstab) to remount as read-only in such cases in order to minimise the risk of data loss."

General :: Kickstart Installation Fails With Error Failed To Read Rpm Header?

Dec 16, 2010

I am running into a strange problem where kickstart installation fails with Error failed to read Rpm header, This happens when installation starts formatting of disk is also completed some of the rpms installed and then suddenly installer stalls with failed to read rpm header.

I have kept kickstart and install media on same host. I have changed the install media from http/nfs/ftp just to check is there any problem with the media but no luck.

However same installation with the same kickstart file works fine when both install media and ks file is kept on another linux host.

I am using RHEL 4 ,I do checked /var/log/messages it does not give any information on the failure and this started happening recently till that i was using the same server for my linux deployment.

Note: pxe setup, boot server ,install media and ks file all are in same server.

Ubuntu Installation :: 11.04 Failed - Crashed Computer - Error "Cannot Read 'etc/udev_rule.d/z80_user.rules"

Jun 1, 2011

I have a laptop set up for dual-boot with Ubuntu and Win7. I also have a shared partition which I mounted as the /home directory in Ubuntu. The problem occurred as I was upgrading Ubuntu from 10.10 to 11.04. In the middle of the install, my computer froze for some reason and ultimately I had to shut the computer off and restart. When I restarted the linux would freeze half-way through boot-up with a message saying that the drive was mounted. Before the message saying the drive is not mounted it gave the following error: Can not read 'etc/udev_rule.d/z80_user.rules'

When I boot up Win7 it is unable to mount the shared partition and says that the drive is not formatted. I am also unable to run the ubuntu recovery option from GRUB. It asks me to give the "root password for maintenance," but it won't accept my root password. Would the upgrade have wiped my partition??? Or am I just locked out somehow because it was in the process of changing config files?

Ubuntu Installation :: No Boot Sector - Hit F1 To Retry

May 11, 2010

I have a rather puzzling error. I recently purchased an usb external hard drive with the intent of installing Ubuntu on it. I have had great success with installing various linux flavors on usb thumb drives but I need a little larger space for engineering applications that I use. Anyway, I removed my laptop's internal hard drive and installed ubuntu 9.10 on a recently formated external hard drive. Everything worked fine at first. Upon restarting I get an error that says "no boot sector" and it asks to hit either f1 to retry. When I hit retry, Grub loads most of the time. Occasionally it does not work. Is Grub just not installing correctly? I searched for this error but I found nothing that directly applied.

Ubuntu Installation :: Win7 Has Overwritten Boot Sector?

Apr 21, 2011

I have been running a dual boot system with Windows XP and Ubuntu 10.10 64 bit with the dual boot selected by Grub (placed y an Ubuntu install).

Recently I have installed Window 7 Home on a spare disc. My Bios allows me to select which disc to boot.

The Win7 installation has overwritten the boot sector on the WinXP/Ubuntu dic so that it is now not bootable.

I can sse all my Ubuntu files with a Live Linux Disc, so I can get all my files back.

Is there any easy way to re-install Grub or should I just do a clean install of Ubuntu, perhaps to a blank partition?

Ubuntu Installation :: 11.04 - Loading VM / Error Reading Sector

Sep 1, 2011

I created a boot disc (USB drive) with Ubuntu 11.04 and tried to install it on my Gateway GT5012 desktop running Windows XP. It gets to the part where I can "Run Ubuntu from this USB," and I select it. The screen shows "loading vm/linuz..." or something like that, and then the entire screen turns into dots.

One time, when trying to boot from the drive, it brought up
"CHS: Error 0201 reading sector 1418005 (88/68/3)
EDD: Error 4200 reading sector 1418006"

I ran this same USB drive on another computer (also running XP), and it worked just fine, so I really have no idea what's going on. If it matters, the computer it worked on had Internet access, this one didn't. It says "Loading /casper/vmlinuz..." and then goes to the screen of flashing dots.

Ubuntu Installation :: Device /dev/sbd Has A Logical Sector Size Of 4096?

Jan 16, 2010

So when i install ubuntu it gets to 47% and than i get this error message. After that the install doesn't really seem to do much.Code:Device /dev/sbd has a logical sector size of 4096. Not all parts of GNU Parted Support this at the moment, and the working code is HIGHLY EXPERIMENTAL.Now i did search and i found another topic where someone had the same problem. His solution was to reburn the CD and try again. I did that and it still got me the same messageP.S. I do have two boot options now however. One for ubuntu and one for windows though i already ran the uninstall.

Ubuntu Installation :: GParted Hangs Because Of Sector Size Error

100MB Windows 7 Reserved
900GB+ Windows 7

Is there a workaround for this? I've tried installing Linux Mint and Ubuntu but both gave me the same error.

Ubuntu Installation :: Grub Fails To Be Written In Boot Sector / What I Need To Do?

Nov 21, 2010

I am a complete noob at this and I need a hand. I was about to throw my computer out of the window when I decided to throw the windows out of the computer so to speak. So, I downloaded Ubuntu 10.10 and tried to install. I had a grub rescue after the installation (file system unknown), which I have seen discussed here. Being the noob that I am I decided to try 10.04 because it said it had full support. With this install I get a similar error during installation: grub cannot be installed in boot sector.

So, basically there is an issue with grub and the boot sector. I checked in my BIOS options to see if there was an option that prevented the writing of a boot sector or something, but I have not been able something like that. So, I am wondering if it is possible that Ubuntu does not really erase/format the selected disks or something, leaving any difficulty there.

Does anybody know? Or better yet: what exactly do I need to do a manual grub install?

Ubuntu Installation :: 11.4 - Grub2 Kills Windows Boot Sector

Apr 30, 2011

Been away from linux for a few years thaught id come back and give it a try again. I have Win7 on sda and installed 11.4 Ubuntu on sdb. Grub2 Over wrote the boot sector for windows so windows wouldnt show in the boot menu. I repaired that after some research and then tried it again with 10.4 LTS version of Ubuntu. Same thing. Now I've fixed windows boot sector a second time and im ready for round 3. Any hints on how to get grub2 to boot both OS's? Ubuntu 10.4 is still on sdb I think I should just need to re-install grub2 But how to do it without Killing the windows boot sector?

Debian Installation :: How To Copy USB Key Boot Sector To HD

Aug 20, 2010

I just installed squeeze from a usb key. Installation went flawlessly but now I need the usb key to boot. Nothing happens if I let the bios boot from the HD or if I force it to do so. When it boot up from the usb key, the HD is read and the boot up sequence continues. Grub seems to be installed in /boot/grub. I imagine that I have to copy the usb key boot sector to the HD but how?

Ubuntu :: Config Failed - Cannot Read Hub Descriptor

Mar 2, 2011

I have been unable to find a site with information on what err -22 means. From what little I have found on the issue it seems to be something with the usb 3.0 hubs on the back of my motherboard?

Ubuntu Installation :: Delete Grub From Boot Sector In HD Of Toshiba Notebook

Jun 7, 2010

I have a toshiba notebook with Windows XP and Ubuntu studio. I removed Ubuntu partitions with the idea to install classic Ubuntu, but... grub don't recognize Windows to boot. I formatted the hard disk as slave from another PC. I installed Windows again trying to delete the grub, but, it is already there. I am trying to repair grub from Windows with: FIXBOOT, FIXMBR, fdisk /mbr from MS DOS, but that is not working.

Any suggestions:
- To delete the hard disk complete and start again everything. (deleting grub also)
or
- To repair boot sector for Windows

Ubuntu Installation :: Installing On External 1tb Disk With 4096 Sector Size?

Dec 9, 2010

In the past I have been able to succesfully install ubuntu on several external usb drives with up to 500gb in size.Now I am trying to install a copy of ubuntu 10.10 on an external usb iomega 1tb eGo drive but I am having major issues.The installer reports the total disk size as only 124 gb, instead of the 998gb that gParted reports for the same disk. Proceeding with "use the full disk" installs ok, but it doesn't boot.Grub2 reports that it cannot find the kernel.After some desperate attempts to repartition and after some googling I think that the issue may be with the sector size, which fdisk -l reports as 4096kb (all my other drivers report 512kb) and I have the impression that linux is not ready for it (or I lack the knowledge, which seems more likely).I have also tried to install fedora 14. This distribution reports the correct disk size, installs properly, but again, it cannot boot (Fedora uses grub, not grub2), with a very similar message to the grub2 installer.Because of the way I work, I need my external usb drive to be able to boot linux. And I find it difficult to believe that linux doesn't handle 4096kb sector disks, so here I am asking for help . Please note I am not a linux expert.

Fedora Installation :: Partition Does Not Start On Physical Sector Boundary?

Aug 22, 2011

fdisk -l: Disk /dev/sda: 750.2 GB, 750156374016 bytes.

[Code]...

I've tried other installations, but I always get errors like this. /dev/sda 5, 7 and 8 are occupied by PCLinuxOs. /dev/sda 9, 10, 11 and 12 by Fedora. I made room for Linux installations by GParted (last version). Really, I made no errors. The installer of PCLOS is a bit strange: it changed the NTFS partition sda5 in sda 6! In a previous installation with Fedora and Kubuntu only the extend partition sda 4 complained about not starting on physical sector boundary. The hard disk is Western Digital with Advanced Format. Probably this is the cause of the problem. The systems are snappy and responsive. I do not encounter any problem. What to do? Ignoring the problem or reinstalling? May be it would be better to get rid of PCLOS and to dual boot Windows with Fedora?

Debian Installation :: Found A Bug In The Installer \ Enough The Boot Sector Showed As Blank?

Jun 26, 2011

I had ubuntu studio installed ( for the record I hated it and every ubuntu flavor I have ever used. ) After backing off all the stuff from my home dir I started to install testing from a dvd. ( Is there a net install for testing? I couldn't find it) Don't ask me how it happened but some times I would have two grub graphical boot menus. One would chain to the other. I suspect that happened from one of the very friendly updates ubuntu did. Well when I tried to install testing I got a red screen telling me that grub wouldn't install so I tried lilo. Well it wouldn't install either. Back in the old days when I was a slackware guy installing from a stack of floppies I had a trick to wipe out any boot loaders or other stuff that gave me a problem. I would dd if=/dev/zero of=/dev/<drive info such as hda with no partition number> .

This would write zeros over the drive and it would look like a new drive. So I did this trick. But still no joy ( this is a clue, dd was also thinking that the beginning of the drive was after the boot sector.). I suspected that the installer wasn't doing it's job right. So I got a PCLinuxOs disk and started that installer. The PCLinuOS installer has a cutesy visual bar that shows the partitions. Well sure enough the boot sector showed as blank. This was what the Debian installer had done. It left the boot sector blank and tried to install the boot loader right after it. This won't work. Now I consider when some version of Linux falls on it's face and another version does it right that the version that fell on it's face has a problem.

One might even call it a bug. But I don't know what to do about it. I don't think the problem is with grub or the installer itself. I think how the drive was looked at was faulty. That's why dd didn't blankout the boot sector. So what do I do to help get the Deb people to fix this? The more I think about it the more I think the problem is with udev ( what a surprise) I think this because I suspect dd looks to the info set out by udev to find the beginning of the drive.
