Ubuntu :: GParted Doesnt Regognize Table?
Oct 31, 2010
Im trying to do a new install(32bit to 64bit) but Ubuntu installer doesnt see my partitions nor does this installation. "Disk utility" sees them fine and im running my Ubuntu and XP on that disk. I dont wanna lose my XP and /home(Koti) partition so help needed.
Theres my fdisk -l:
Code:
Disk /dev/sdb: 160.0 GB, 160041885696 bytes
255 heads, 63 sectors/track, 19457 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

I upgraded Windows to 7 from Vista. My Acer laptop had a recovery partition with Vista on it. I don't know, what I was thinking, after the update I deleted the recovery partition. Then got in to problem that Partition Table is deleted. Recovered the partition and partition table with LiveUSB and gpart.
So laptop was working again in about 30mins. Now I see the following issue. Laptop boots and works fine both in Ubuntu (default OS) and Win7. In Disk Utility the partitions are shown as in attachment. In Gparted the disk is not recognized as partition table is not recognized (so I guess) Output of fdisk is here for ref;
Code:
home@home-laptop:~$ sudo fdisk -l
[sudo] password for home:

While installing Ubuntu I have created 50MB boot partition and was sure is enogugh, but now with growing initrd and kernel size, an autoupdates which were always killed by no sufficient disk space I decided to increase its size. I had following partitions - in disk order:
sda1,primary bootable NTFS, 57GB
sda4, primary ext2, /boot, 47MB
extended sda2{
sda6, ext3, /(root), 43GB
8MB gap
[Code]...
Is the problem still in bad begining of the partition saved or data are already broken ? If the first is there any mount option to really not touch filesystem ? Because I've read even if we mount readonly there are some options saved to disk (as last mount time etc) and I'm aware it could destroy entrie filesystem.
Has the ext3 some partition header as NTFS do? Or is there a way to locate real start of partition? because testdisk and gdisk shows only this one starting sector for sda6. When I moved the sda6 partition there was space between begin of extended partition and begin of sda6, now there is no space, so that's the main reason of suspecting partition begining is in fact over 100MB further.Current partition schema in attached PNG. Also the swap partition was deleted, I don't know when, now there is 4GB hole.

This machine has UBUNTU & wINDOWS XP. I'm currently logged into UBUNTU. I was just checking the features of GParted and accidentally clicked Device > Create Partition Table. A default MS-DOS partition table is created. Now if I re-start the Gparted there is nothing. Its showing entire disk as UNALLOCATED space.
Lucky thing is All the drives (C:, D:, E:) are currently mounted and I'm in UBUNTU. I guess its possible to re-create the partition table using current status. how to do this. This is a lab computer. If its not recoverable. I'm completely screwed!

GParted tells me my hard drive is not partitioned and has an unrecognised partition table, but I know it has because i'm using it now to write this on here, and fdisk shows the following:

Anyone know of anyreason GParted may not be working or can offer an alternative to create a partition?

I have installed HP g6 notebook from live-cd with 10.04 LTS across multiple partitions, only to find that the partition table is not setup correctly. I place the following mount points on separate partitions:

When I start gparted, to see if I can add extra harddisk where all my data is, I get the next error:
Code:
[root# gparted
libparted : 1.9.0
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 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?

I have 3 Ubuntu installations & a PCLINUXOS, plus Windows XP installed on one hard disk. I still can boot to each one of them and can mount each one using Ubuntu.
The problem "may" have occurred when I reduced the size of some linux partitions using gparted. I still have plenty of space in each of those partitions.
When I started gparted all of the HD was unallocated. I did that from each ubuntu installation and the PCLINUX installation, plus LIVECDs. All indicated the space was unallocated.
When I did an fdisk -l from a Puppy Linux LiveCD I got a normal start and ends of each partition.
When I tried it from Ubuntu installation or live cd, I received the following types of responses:
Code:
ubuntu@ubuntu:~$ sudo fdisk -l /dev/sda5
Disk /dev/sda5: 28.5 GB, 28566397440 bytes
255 heads, 63 sectors/track, 3473 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Disk identifier: 0x00000000
Device Boot Start End Blocks Id System
ubuntu@ubuntu:~$ sudo fdisk -u /dev/sda5
The number of cylinders for this disk is set to 3473.There is nothing wrong with that, but this is larger than 1024,and could in certain setups cause problems with:
1) software that runs at boot time (e.g., old versions of LILO)
2) booting and partitioning software from other OSs (e.g., DOS FDISK, OS/2 FDISK) Plus the Windows partition seems to go over its limits.
Since all of my OS installations are still working, I don't know how critical this is. From reading another post, I understand this might be able to be fixed by making some changes in fstab.

We purchased a virtual server from GoDaddy (1 month trial) to set up as a proxy for our networks (24 of them). I am having 2 separate issues. The first is I can't configure/install NAT and support is telling me the only way I can is to purchase a dedicated server. Here's the error:
iptables -t nat -A PREROUTING -p tcp --dport 80 -j REDIRECT --to-port 3128 iptables v1.3.5: can't initialize iptables table `nat': Table does not exist (do you need to insmod?) Perhaps iptables or your kernel needs to be upgraded. Here's the fix: [URL] So, what I am hoping to do is configure this by just opening port 3128 directly, and only allowing access from our networks. As a test I did this and allowed only from our office and it did not work. However I can't connect, so I am wondering what I am doing wrong? Here's my squid configuration:

i've come to replacement my 80 yr old fathers win98 machine with lucidFirefox 3.6.3 says 'connecting to .....' when accessing a webpage (eg his home igoogle page,bbc.co.uk ) and then times out .It all works with opera and links2 and pings are the usual times and its doing DNS . I've added 4.4.4.4 and 8.8.8.8 to /etc/resolv.conf for good measure FF its configured NOT to use a proxy ( Im fed up looking and checking !) and ive tried the 'detect settings automatically'this is a 'mission critical' step. Going to linux is a big enough change , so getting FF working will be a deal-breaker

I have a computer that i wish to install ubuntu 10.04 on, it wont install tho, it tells me that it cant detect the cd rom (the drive it is booting from) and that i should insert a removable device with the drivers on it, except i dont have those and don't know where to get them. i cant boot from a usb but i have a usb with 10.04 on it just incase. i tryed this with both alternate install and desktop. i dont know what to do, i have invested 2 days to try and do this and i would really like to put this on my computer.
I have previously installed 8.04 on my computer with out such error and all of the hardware is the same (even the hard drive), and i lost the 8.04 disk. <(it was a live disk)

got a problem after running updates on my 10.10 install. PC doesnt boot at all gets to loading OS then just powercycles. UBUNTU is installed on a 2 disk raid0 array which seems to have changed. It used to run /dev/dm-1 for the root and /dev/dm-2 for the swap
Ive booted to a live cd and it now shows /dev/dm-2 for the root disk and -3 for the swap so im guessing grub is failing. Unfortunately I cant seem to get the device to mount and I fear im going to have to reinstall to fix this.

I am running xubuntu 11.04 (ISO from early this week). During install, I selected to NOT auto login but to present this gdm panel where I have to enter the password (or other users could log in).
Now I decided to enable auto-login (and to start the screensaver right afterwards) ... so I opened up the "login screen settings" (systems menu), unlocked that window and changed it to "login as xxx".
Then i rebooted and would have expected to be greeted with my screen saver on a logged-in session afterwards. But what happens is that there is a gdm panel sitting ... showing me
AUTOMATED login
Other
Where the first item wont do anything.
So I have to select other and enter user name + password ?
Is that how it is supposed to work?

I am using eiskaltdc in Ubuntu 11.04. Its working very fine. But after I clicked on the "cross" button its gone. Normally in 10.10 there was a small icon in the bar for that eiskaltdc, but in the new Unity its not there. I checked the system monitor and it shows eiskaltdc. Any idea how to maximize it?When I logged in with Ubuntu Classic GNOME desktop I was able to find the minimized window. But in Unity its totally hidden .
