then:

My friend gave me a flash drive with some important files on it that one day didn't work with his windows box. Upon plugging in the thumb drive, Windows gives a "you must format this disk before it can be used" message. I tried running a data recovery program (Easeus) on it but didn't have great results- only recovered some .wav files, a few .avi files and a .exe- none of which were very important, so I figure'd I'd try to mount it in Linux and possibly see the rest of the filesystem. The thumbdrive is a 2GB Lexar JD Firefly I plugged in the thumb drive and it is picked up by the system, but I can't access it. Here is the output of lsusb

I believe this has something to do with an mdadm update which was included in the release. When I configured the array, I didn't partition the disk devices, so maybe that has something to do with it. I am thinking of rebuilding the array and partitioning prior to build, but a quick fix would be referable.
And also something appears to have happened to the raid device since the update.
Prior to update, the array was /dev/md0 - now it is /dev/md/0 which is a symbolic link back to /dev/md0.
mdadm --detail --scan now reports /dev/md/0 where previously it reported /dev/md0
I created a new RAID1 array on a fresh system and immediately after the create, these messages appear at 5 minute intervals.
a windows installation on a fake-raid, /dev/mapper/ddf1_AR01p1 and an xtra penguinFS on ddf1_AR01p2. I simply tried to boot "Super Grub Virus" from a usb stick ... and the $%!($ER hosed the array. Luckily, my day to day OS and important data is on a different set of disks ... but my BIOS boot target is set to the fake-raid, so it did not kill anything genuinely important ... I just got lucky.
I would really like to restore the windoZe partition as it WAS. I actually use it a couple of times each year. I would just reinstall the OS ... really NOTHING important on those 2 disks, but I have no idea where my XP disk can be found ... but I know the xp installation is hiding in /dev/null ....
Is there a difference between using GPT partition table when formating hard drives and MS-DOS partition table? What are the advantages/disadvantages of using either?

Just delete a linux partition and now when i boot a message appears and says error: unknown filesystem grub rescue >
I have search on the net for this problem and i have understand it a little. But my situation is a bit different and because i don't want to format my hard disc i wanna try to fix it. So before a couple months i download ubuntu 9.10 and i installed it a month later. But my computer used to crash all the time and i couldnt use it. So i download the latest ubuntu 10.4 and install it while having windows xp and the old ubuntu 9.10(so i had windows xp, ubuntu 9.10 and ubuntu 10.4 partitions). Now i tried to delete the partition of ubuntu 9.10 from disc utility. so i have the message i wrote above when i boot. I dont wanna delete my windows xp and ubuntu 10.4. what should i do to stop this message from appearing.
I have encountered something of a mystery here. The other day while in /dev I ran 'ls sda*' and noticed this...Quote:

I'm trying to install Fedora 10 from a USB memory stick on which i've installed Fedora-10-x86_64-DVD.iso and, early in the process of configuring the installation, i get messages about both my IDE hard drives having unrecognizable partition tables:
"The partition table on device sda (... my disk data ...) was unreadable. To create new partitions it must be initialized, causing the loss of ALL DATA on this drive."
Same for sdb.
My PC currently runs Fedora Core 4 (yes i know i should have gotten around to upgrading my OS earlier) and yes it recognizes both hard drives just fine.
The answers I've found on the web suggest to backup my drives and repartition. I'm not too hot on that "solution".
explain why a F4 partition table is not recognized by F10?
BTW, I've recently upgraded my motherboard, processor, DVD drive, regrouped both my IDE drives on the same bus, ... I consider it a miracle F4 still runs on this PC (although F4 does not support the motherboard's graphics card, so no X11).
I have installed the fedora 13 x86_64 live cd. I updated fedora as well as installing gparted.y hard disc containing my operating systems is not being read by gparted.unalloacted partition table.

View 7 Replies View RelatedI have a Toshiba laptop, running Vista Home Premium SP2 with AMD Athlon 64 X2 Dual-Core Processor, 1 gb ram & 150 gb HDD. I just shrunk the c: drive down to 92 gb to free up 43.5 gb so as to load the Fedora Linux OS into this free space & have a dual-boot configur'n. My problem is the partition table in the MBR. It shows 4 partitions there, so the fedora 13 Live CD which I use to install the OS cannot find a free spot in the partition table. I have the Ultimate Boot CD so I took a look at the MBR. Here are the 4 partitions that occupies its table:
1. (no drive letter) - file system: blank - EISA config'n - 1.46 gb - partition type code: x27
2. C: - fs: ntfs - system, boot, active, primary partition - 92.01 gb - code: x07
3. D: - fs: ntfs - primary - 5.98 gb - code: x07
4. (no drive letter) - fs: blank - primary - 5.64 gb - code: x17
c: is 17% free, d: is 99% free, the other two are 100% free Can you explain what is the purpose of D: ? How about the other two (with no drive letter)? I read somewhere that 'x17' code means 'hidden IFS (ex: HPFS)' & 'x27' means a rescue partition... true?
Would I be safe in replacing the partition table entry for #1, 3 or 4 with an entry for my Linux? (I have an editor that could modify the MBR). Or would it be better to leave MBR alone, put a boot program on a CD or USB stick, which boots Linux from the unallocated 'partition'? (have to somehow manually install Linux to the 43.5 gb area that I freed up).

During a recent request to install fedora 11, I ran into an interesting problem. It seems that between fedora10 and fedora11, the developers switched from fdisk, to parted for creating the initial pre-mke2fs partition table creation.
It looks like the implementation of this is broken, as it's writing the partition table with overlapping cylinder boundaries. While this can sometimes be ignored, it can in certain cases cause significant data corruption.
On an installation I took it through, using the latest installation media, in both manual & automatic partition creation, the layout looked like this:
The last two partitions turn out fine, for some reason. However, those two partitions should not have overlapping cylinders. After my very first installation, the system was completely unbootable, and not even fsck wouldn't rescue it. If this is possible, then that means that a system that's been online for months or even years could simply drop out of functionality simply due to a byte or two of system-critical data falling on that last cylinder. Considering that a lot of the time kernel data ends up on /dev/sda1 (commonly the /boot partition), this is something that should not be ignored.
Will deleting dev/sda partition table ( msdos ) affect my windows 7 system? I am trying to install Fedora 15 on Virtual Box.

The kernel was unable to re-read the partition table on /dev/sda (Device or resource busy). This means Linux won't know anything about the modifications you made until you reboot. You should reboot your computer before doing anything with /dev/sda. I can start fedora 12 x64 amd whitout any problem. My partition layout on a single disk (80 gb sata maxtor) for the system is:
Code:
/
/home
swap
When I try to mount one of the extra disks (samsung spinpoint 1 tb, I have 4) I get to next error:
Code:
root# mount /dev/sdb1 /media/sdb1
mount: you must specify the filesystem type
If I add the option with the filesystem I get:
Code:
root# mount -t ext3 /dev/sdb1 /media/sdb1
mount: special device /dev/sdb1 does not exist
In gparted, when I select just a flag option, and deselect, press ok, the disk is forced to be reread by the program. After that I can also mount it. When I use any of the programs linked in this post, I am able to mount the disks whitout any problem. Except after a reboot, I get the same problem. SO whit each reboot, or poweroff, I need to do a re-read of the disks. The system is fedora 12 x64 for amd, installed from a live cd, the rest whit yums groupinstall, the latest kernel.

I have tried to automate the configuration of a usb drive with not much success.
The problem that I have is that I have a large amount of usb drives that have a partition table of type "loop" and I need to change them to "msdos". The size of the drives vary and I need to use FAT32 or FAT16 file system.
I've tried various partitioning commands and gui applications but cant find one that I can give a one line command to to set the partition table, maximum partition size and file system.
I was reading another thread about someone with a bad partition table and I decided to join this forum. I'm not going to take any drastic actions with the partition (/dev/sda3) in question. I am going to wait for instructions on what to do first. I am not very good with Linux and need some hand holding. System: DELL 4550 Dual-Booted with XP and Ubuntu. Works OK, just no swap. Well, here's what I did: I deleted a partition for Windows XP Pro because it was a trial, and it ran out. I then decided to slide the swap partition for the Ubuntu Linux that I dual-boot into over. (If this was successful, I was going to try expanding the root partition to take up the unused space.) I used Gparted on a CD to do this, as I figured it was safe to do.
I now cannot mount the swap space at bootup (and have to go into a backup version of the OS), although I can use Gparted in Linux to execute the "swapon" command, and it appears that it worked because I now see "swapoff" as an option on the context menu. (I actually don't even need a swap partition, except to hibernate.) If I highlight the swap partition and click on "Drive" on Gparted's menu bar and select "Create Partition Table", it will erase all data on /dev/sda, so how do I fix the bad partition table non-destructively?
Everything is installed and setup on my system, but when I setup my partitions I chose my Windows partition to be bootable. Can I just use cfdisk to toggle the bootable flag so my linux partition is bootable and rewrite the partition table?

Is there a program that will reread the partition table and update the kernel even if one of the unmodified partitions is mounted? I installed my system on one partition, then I added another with free space. Now I want to format the second partition, but the kernel doesn't know about it yet. I tried sfdisk -R /dev/sda, but it refuses while the root partition is mounted. Is there anyway I can avoid rebooting?

Where did the partition table go? The device had one ext3 partition something around 4GB(size of USB storage device). I need to restore few files from this device.
I'm trying to clone a Linux install to a different laptop. It's made a little complicated by two facts:
1) The 'new' laptop I'm trying to copy my Linux installation to is actually older and has a smaller hard drive then the computer I'm copying from
2) The computer I'm copying from has both a windows and Linux installation; I only care about the Linux partition.
I figured I would copy only the Linux partition from my primary computer to the laptop, sense the laptop doesn't have a large enough hard drive to copy everything. So I used the DD commands to copy SDA3 (main Linux partition) from my main computer to SDA2 of my laptop. When I came back a few hours later I was surprise to find my laptop trying to reboot itself (I never turned it off). It would keep starting to reboot, failing, and restarting itself. Not too surprising sense its boot partition wasn't changed so it's trying to boot into centos when I copied a redhat partition to it.
The problem is that when I used a redhat boot disk the rescue mode was unable to find a Linux partition to mount. /dev/sda2 exists, but trying to mount it gets the complaint "No such file or directory". "fdisk -l" lists sda1 (the boot sector) and sda2. Sda2 is the correct size and reports Linux LVM for its system. But "fdisk -l /dev/sda2" gives the error message "Disk /dev/sda2 doesn't contain a valid partition table" Did I not clone the drive correctly, or was an error caused due to the boot sector not being copied yet (the laptops boot sector is smaller then my old computers, so I can't copy from old computer to laptop)? Can I salvage the laptops partition table somehow, or do I have to repeat the cloning process? And if I do have to re-clone my computer can anyone tell me what I did wrong the first time so it works this time? I don't care if I copy just the Linux partition or both windows and Linux. Even though my main computer has a larger hard drive I'm only using about half of its available space so it should be possible to copy both partitions if I could ignore the unused sections of the harddrive.
Edit: I used DD to copy a tiny part of the Linux partition from my laptop so I could look at it. Most of it is illegible binary of course, but I scrolled through till I found some text right near the beginning:
Code:
VolGroup00 {
id="F2MWxh-....-BidcLe"
seqno = 1
[code]....
So it seems that the DD command did copy everything over to the laptop, which is good to know. I noticed that it says device="/dev/sda3" right in the middle of the code I just posted. The Linux section of my original computer was SDA3 but I copied it to partition SDA2 of my laptop. So is the problem because the boot partition is for the wrong device? I don't suppose if I modified that one line to say SDA2 it would be able to load correctly? (Not that I know how I would modify the line, short of using the DD command again).
