Mar 8, 2011

Fedora Hardware :: New Hard Drive - Disk Unreadable Errors

Dec 16, 2010

I had a set of rather unusual problems on installing a new 500Gb hard drive on my F14 system, I've solved them, but they were that unusual that I thought I should share them in case anyone else gets the same thing! I'd been experiencing intermittent faults on one of my drives, (lock ups for no reason, occasional boot ups that failed due to ' disk unreadable errors' and other odd errors). I assumed that the drive was failing, but it always showed 'Heathy' on disk utility! This was the disk with the OS on, plus my main 'data' disk had some bad sectors, so I thought I'd buy a nice big 500Gb and reinstall the whole system.

I backed up all my data to an external 'USB' drive, opened the case, (a big old under the table 'desktop', why do they still call them 'desktops'?) shoved in the new SATA drive and rebooted, intending to format the new drive to EXT4 and partitioning it before installing F14 again! OOOOOOOOOW! Major drive failure, missing OS, whole list of SDB errors! Control D, to reboot, BIOS only sees one drive; SDA (I have three, two IDE and one SATA) plus the one I just put in makes four. I go into BIOS and discover that it not only cant see any of the other drives, but my two DVD drives are missing too!

Now I've been building my own systems and mucking about with computers since before you could buy them, and Ive never seen a problem like this one! At first I thought the new drive had screwed my system, for on removal, the problem persisted! Then I noticed that the IDE connector in drive SDB, (the long 40 pin job) was just slightly out of line with the back of the drive, pushed it firmly in and what do you know, everything works! We moved recently and I think the vibration was enough to loosen the connector to give intermittent faults, and pulling the cables about to get the new drive in, pulled it out further......

Ubuntu :: Unreadable WD MyBook Terrabyte Drive On 10.04 LTS?

May 8, 2010

I've been using a WD MyBook terrabyte USB drive for several months with no problem. Several days ago, I used the "safely remove drive" option but then unplugged the cable before the removal process had finished.

Now when I plug the drive in, the WD SmartWave section of the drive will mount. This is additional software for Windows computers that came with the drive and that I don't use. The main drive itself, though, will not mount. The drive doesn't show up on the left side of a navigation window, either.

I can see the drive using Disk Utility. It is located at /dev/sbd. (a) mount this drive or (b) recover its data so I can format it? I'd much prefer (a), of course. Regarding my level of tech savvy: I've been using Ubuntu for a couple years, but I chose Ubuntu because it allows me to use Linux while still remaining relatively ignorant about things, which is my comfort zone.

Ubuntu Installation :: Error: Out Of Disk. Grub Rescue>

Dec 11, 2010

Trying to do a new install of ubuntu 10.10 to my laptop. Installation and all works fine, but upon rebooting, after the bios screen i get:

Code:
error: out of disk.
grub rescue>
I tried using following some instructions i found after googling for the problem:
Code:
ls (displays the partitions and devices Grub can see)
set prefix=(hdX,Y)/boot/grub

[Code]...

but after the 5th step, i get another "error: out of disk" message. The odd thing is that I had an install of 10.10 on this laptop a month ago, and it worked fine. As a side note, I installed fedora 14 after this happened, which worked fine. Reinstalled ubuntu, and it was back to the same problem. I also tried installing with a kubuntu cd I had, to make sure it wasnt the install media, and had the same problem.

Software :: Rescue Windows Hard Disk With Knoppix?

Oct 23, 2010

I wanted to get the data off the WD2500 (250MB) hard drive so slaved it to an older Dell machine running Win 2k. Unfortunately, the older machine's BIOS is so old it can't read the larger hard drive. Then, I connected it to a Gateway machine running Win 2k; it started running chkdsk on the WD2500 drive and indicated it was 'fixing' a bunch of errors. It appeared to be in an endless loop, fixing the same problem over and over, so I killed the power. Then, I booted the Gateway machine with Knoppix Live CDIt shows the 250G hard drive in the file manager window. When I click on the 250G hard drive icon it shows at the bottom of the window '1 visible item (0 hidden), Free space: 97.4 GB (Total: 250.0 GB)This seems about rightHowever, the file listing only includes a single item, 'Documents and Settings' of size 4.1 kb. So something to do with the directory structure is corrupted, but I don't know what, and I don't know how to fix it

Debian Installation :: Grub Rescue - Will Not Boot From Mdadm RAID - No Such Disk

Sep 19, 2014

I am running a 14 disk RAID 6 on mdadm behind 2 LSI SAS2008's in JBOD mode (no HW raid) on Debian 7 in BIOS legacy mode.

Grub2 is dropping to a rescue shell complaining that "no such device" exists for "mduuid/b1c40379914e5d18dddb893b4dc5a28f".

Output from mdadm:
Code: Select all    # mdadm -D /dev/md0
    /dev/md0:
            Version : 1.2
      Creation Time : Wed Nov  7 17:06:02 2012
         Raid Level : raid6
         Array Size : 35160446976 (33531.62 GiB 36004.30 GB)
      Used Dev Size : 2930037248 (2794.30 GiB 3000.36 GB)
       Raid Devices : 14

[Code] ....

Output from blkid:
Code: Select all    # blkid
    /dev/md0: UUID="2c61b08d-cb1f-4c2c-8ce0-eaea15af32fb" TYPE="xfs"
    /dev/md/0: UUID="2c61b08d-cb1f-4c2c-8ce0-eaea15af32fb" TYPE="xfs"
    /dev/sdd2: UUID="b1c40379-914e-5d18-dddb-893b4dc5a28f" UUID_SUB="09a00673-c9c1-dc15-b792-f0226016a8a6" LABEL="media:0" TYPE="linux_raid_member"

[Code] ....

The UUID for md0 is `2c61b08d-cb1f-4c2c-8ce0-eaea15af32fb` so I do not understand why grub insists on looking for `b1c40379914e5d18dddb893b4dc5a28f`.

**Here is the output from `bootinfoscript` 0.61. This contains alot of detailed information, and I couldn't find anything wrong with any of it: [URL] .....

During the grub rescue an `ls` shows the member disks and also shows `(md/0)` but if I try an `ls (md/0)` I get an unknown disk error. Trying an `ls` on any member device results in unknown filesystem. The filesystem on the md0 is XFS, and I assume the unknown filesystem is normal if its trying to read an individual disk instead of md0.

I have come close to losing my mind over this, I've tried uninstalling and reinstalling grub numerous times, `update-initramfs -u -k all` numerous times, `update-grub` numerous times, `grub-install` numerous times to all member disks without error, etc.

I even tried manually editing `grub.cfg` to replace all instances of `mduuid/b1c40379914e5d18dddb893b4dc5a28f` with `(md/0)` and then re-install grub, but the exact same error of no such device mduuid/b1c40379914e5d18dddb893b4dc5a28f still happened.

[URL] ....

One thing I noticed is it is only showing half the disks. I am not sure if this matters or is important or not, but one theory would be because there are two LSI cards physically in the machine.

This last screenshot was shown after I specifically altered grub.cfg to replace all instances of `mduuid/b1c40379914e5d18dddb893b4dc5a28f` with `mduuid/2c61b08d-cb1f-4c2c-8ce0-eaea15af32fb` and then re-ran grub-install on all member drives. Where it is getting this old b1c* address I have no clue.

I even tried installing a SATA drive on /dev/sda, outside of the array, and installing grub on it and booting from it. Still, same identical error.

Fedora Installation :: Mount NTFS Partition From 10 Rescue Mode/Disk?

Mar 9, 2009

Background for the problem:

A. I have partitioned my WinXP LTop into:

--- WinXP NTFS partition
--- a vfat partition (mounted onto /fat32)
--- Installed F10 on ext3 virtual partition

B. I do not want install grub-loader in the Master Boot Record (that would loose my WinXP boot-loader for ever)

C. I have installed grub boot loader in the First Boot Sector

D. Now I have to boot using Rescue Mode, do:

1. dd if=/dev/sda2 of=/fat32/linux.bin bs=512 count=1
2. mount -t ntfs /dev/sda1 /ntfs
3. cp /fat32/linux.bin /ntfs
4. modify /ntfs/c/boot.ini and introduce the statement 'c:linux.bin="Linux"'

Problem: Im not able to do step D.2 above.

Symptom:
** after booting linux using the Rescue Mode: sh-3.2# chroot /mnt/sysimage sh-3.2# uname -r 2.6.27.5-117.fc10.i586 sh-3.2# mount -f ntfs /dev/sda1 /ntfs FATAL: Could not load /lib/modules/2.6.27.5-117.fc10.i586/modules.dep: No such file or directory ntfs-3g-mount: fuse device is missing, try 'modprobe fuse' as root
sh-3.2#

Observations:

* The rescue mode boots into i586 based kernel (I dont know what is the actual difference between i586 and i686 - will really appreciate if anyone can educate me about it). * The installation is only a i686 image and consequently there is *only* '/lib/modules/2.6.27.5-117.fc10.i686' dir and *no* other dir. There is no dir as xxxx.fc10.i586.

Ubuntu Installation :: Initial Boot On System - GRUB Rescue - Error: No Such Disk

Ubuntu Installation :: 10.04.1 Install Fails To Boot -> Error: Out Of Disk, Grub Rescue

Jul 13, 2011

Downloaded Ubuntu 10.04.1 Desktop AMD64, tried to install it to a cleand HDD using the whole HDD, i.e. gave it permission to use the whole HDD. Installation process appeared to run OK but when it came to the restart it just fired up the message

error: out of disk
grub rescue>

I've searched this forum and found numerous references to these error messages but cannot make head nor tail of the diagnostic suggestions. Apart from anything else they suggest strings of command lines which I don't understand and can't enter anyway since they don't correspond to my keyboard layout (if I hit > or ) something completely different appears on the screen). Is there someone here who can provide a step-by-step solution in lay language ? Or is there such a thing as a bootable file which can be downloaded and inserted into my CD drive to correct this problem ?

General :: Error - Unknown Filesystem. Grub Rescue> - No Longer Have The Install Disk For Windows Vista

May 11, 2011

error: unknown filesystem grub rescue>

Background: My mother's HP laptop had Ubuntu and Vista on it, Ubuntu my brother's doing. He decided he wanted to take off Ubuntu yesterday (he had forgotten the password), and deleted the partition that it was contained within. The computer now boots to this error.

Inventory: We no longer have the install disk for Windows Vista, he cannot tell me what version he used of Ubuntu, what partition it was on, any of the specs for the machine, or generally any information about the system. All I am aware of is that error on the boot-up screen. I have nothing else to work with.

I would like to remove Grub, and Ubuntu, and leave Windows intact (the request of the owner of the computer), but I have no idea what commands I could use to get rid of either when I can't access Windows, or how to properly remove them if I did access Windows.

Ubuntu :: Grub Rescue On Netbook (With No Disc Optical Drive)

Jan 2, 2010

My girlfriend has a dual boot netbook I set up for her with Vista + 9.10. Her internet service went down yesterday temporarily and she was messing around with the computer to get back online and somehow booted into the Windows Rescue Partition and began the Windows Restore process, then turned the computer off during the middle of the restore process.It's her only computer and she lives 1800 miles away. And since it's a netbook there's no optical drive.

When she boots up now, the netbook goes straight into Grub Rescue mode. I got her to try most of the commands for Grub Rescue, but most of them come back as "Unknown Command". The "LS" command works though, and she was able to get a list of partitions displayed.Does anyone know of some commands she could use try to boot back into 9.10 (assuming it's still there)? Or even boot into Windows? Specifically, is there a simple command that could be combined with "LS" to specify a partition and try to boot into it?

Ubuntu Installation :: Boot From Flash Drive 10.10 Grub Rescue?

Oct 24, 2010

First time poster and recent Ubuntu adopter. I recently installed 10.10 on my main HD alongside a separate windows (xp) partition (it worked perfectly). Then I decided to get fancy and installed 10.10 to a flash drive directly from a live cd. I attempted to boot from the flash drive, and got a black screen with a blinking underscore for about 10 minutes, then I forcefully rebooted. Now, whenever I attempt to boot at all from my main HD I get "error: no such device and a ton of misc numbers. And the flash drive will not allow me to boot from it. Currently, I'm working within the Live CD.

I have a few projects I need to complete with Dreamweaver inside XP, so recovering it completely would be nice.

Code:
Boot Info Script 0.55 dated February 15th, 2010
============================= Boot Info Summary: ==============================
=> Grub 2 is installed in the MBR of /dev/sda and looks on the same drive in partition #1 for (,msdos1)/boot/grub.
=> No boot loader is installed in the MBR of /dev/sdf

Ubuntu Installation :: Grub2 External Hard Drive - Fails And I Get A Grub Rescue

Feb 8, 2010

I've tried to be clever but as usual I didn't think before acting and missed a small detail.

I have recently installed karmic (dual booting with Vista) on my dell xps laptop. The install went fine, I'm very happy with my new OS.

I bought a new Seagate 500GB portable external HDD. I got a bit over-excited and installed karmic on the external drive. This worked fine and I got a lovely (but slow to appear) Grub2 menu showing my vista and both ubuntu options.

My problem is that now, when I unplug the external drive, Grub fails and I get a grub rescue> prompt. So I need the external drive to be plugged in if I want to boot.

It seems I have done something to the grub configuration. I have read around the subject but I am not confident about how best to proceed.

I understand there is an 'advanced' option in the installer which will allow me to choose where to install grub. Presumably I want it on the internal drive so that I can boot without the external one plugged in.

Am I right in thinking I can just pop in my install disk and redo the installation?

If I indicate I want to install Grub on the internal drive, which partition should I aim for?

Will I get a grub option for booting to the external drive?

Will I be able to plug the external drive into a different machine and boot from it?

I haven't done anything with the fresh install on the external drive so I don't mind losing that.

Ubuntu Installation :: Grub Rescue - Access My Files On External - Failing - Drive ?

Jun 28, 2011

I have an hp laptop and i had ubuntu on it for 3 years. my hard drive started to fail a while ago (i had ubuntu 10 on it until 1 week ago) and a then it all went black...I took the laptop to a repair shop, they told me it was the disc, so i bought a new disc, installed it on my laptop and reinstalled the new ubuntu 11. so far so good. i have now a working OS, internet connection and i can in fact type this message.

The thing is: all my files are on the old drive, which doesn't load/boot/start/read anymore. I have tested it on some friends's pc, tried a few HD disgnostic tools, they all send the same message: "fail"

I then tried to mount my old drive (with all my precious files in it) on my laptop as an external drive (usb) hoping that ubuntu 11 could read it as an external usb key: it gets read by the system, but it shows no files at all. it also shows an error message saying the drive can not be mounted, with some "sdb1" thing. i am sorry but i'm really dumb when it comes to tech language.

Then i tried to boot it on start-up but i got the grub rescue> thing and nothing else, just a sad, blinking cursor to recover my files,i have also tried testdisk but couldn't understand very well how to use it, and then photorec, from which i recovered bits and pieces of files, with no name. some of them are just parts some of them are complete.

My problem is: i have to get access to my files, as I use them for work, i couldn't do a back-up recently and i have some real important deadline to meet... for which i need those files. is there any way i could solve the grub issue and have that drive load/mount again as external usb?

Ubuntu :: Grub2 Isn't Loading Error "grub Rescue No Such Disk"

I ran the "boot info" script and include the results here. One problem I see is that I have grub2 on the MDRs of both /dev/sda and /dev/sdb. BTW: From the Live CD, I can select boot into hard drive and Ubuntu will start up just fine. I can also use "Super Grub" CD and everything loads fine.

Ubuntu :: Deleting A Disk Drive ?

Feb 16, 2011

Ok so basically this isn't my harddrive but hear me out. It's a known issue but it only happened after him downloading stuff off priate bay. The harddrive is not detected on BIOS, so you can't boot through it, just the CD Drive is now detected. You can't use SAFE mode as it reverts to another issue, a black screen with a white cursor, no keyboard commands work.

No restoring disks will fix it nor master disks, it's literally a bad *** issue. Thou I can still load things via CD Drive so I used the Acronis Bootable Media and surely enough, it could anaylse data on the harddrives. I thought maybe i'll try PE Bart but once again, loads up to Black screen with White Cursor. So I put in Ubuntu and yes, I can get on the GUI, but I can't install the operating system.

There would always been an issue. something about in/out whilst installing but as long a I can use the tools, then we go onto Disk Utility. When I try to format, the Error Message apprears stating : Eroor creating File System: helped exited with error code 1: Error calling fsync(2) on /dev/sda2: Input/Output error. This would be the same error i would get via installing and I would have to ignore and eventually whilst installing, from being complete on the right hand side, it would say ERROR or ABORTED after 70,000.
