A couple of years ago, I got a 2TB drive and installed Debian on it.
I used the standard installation procedure, as I recall, and created three partitions, which are shown below in the output of "fdisk":
I want to change my sda2 partition to ntfs type. i have installed GParted but it is returning a strange type of error. Here is the error dump file...

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?
View 2 Replies View RelatedI 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.
USB flash disk partition disappeared as well as partition table I'm not sure about the cause
Code:
root@u# less /var/log/syslog
usb 5-1: New USB device found, idVendor=058f, idProduct=1234
usb 5-1: New USB device strings: Mfr=1, Product=2, SerialNumber=0
[code]....
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 have a problem with one hard disk,now it says its Unallocated,and i tried to create a new partition on it,but it says that first i need to create a partition table,but when i create one,choosing msdos label,it doesnt to nothing. I used Gparted in Fedora,how can i create a partition table,so i can use my hard disk again?

View 1 Replies View RelatedI need to find a program or a way to edit the partition table and set the values and addresses for the partition boundaries manually. A while ago I had a very messy data loss that left me with a disk full of data but without a partition table (and without file indexes for some of the partitions on the disk). So, for recovery reasons I need to try lots of combinations of starting and ending addresses for each partition. Additionally it would be extra nice if I could do this with a live cd since I don't have the faulty drive attached to a working computer at the moment.
View 6 Replies View RelatedI was having trouble creating a USB Startup Disk in Ubuntu and used the command:
sudo dd if=/dev/zero of=/dev/sdb bs=1M count=1
This was a mistake as my USB flash drive was on /dev/sdc. If I am understanding this correctly, the command above deleted the MBR and the partition table. This disk had a single "/storage" partition on it. I googled a solution and found that the "testdisk" program seems to be the most popular solution for things like this. I ran it, selected an "Intel/PC partition" type, set the partition to a non-bootable primary Linux partition, wrote it, and rebooted.
Whenever I run:
sudo mount -t ext3 /dev/sdb1 /storage
I get:
mount: wrong fs type, bad option, bad superblock on /dev/sdb1, missing codepage or helper program, or other error In some cases useful info is found in syslog - try dmesg | tail or so
Dmesg shows the following:

[20246.279376] EXT3-fs: group descriptors corrupted!
When I run:
sudo fdisk -l /dev/sdb
I get:

I am trying to install Gentoo. Currently I have windows 7 on my primary Hard Drive.I decided to add in a second HDD that I got for free and use linux on that.I got through my entire install and at the end I accidently wrote grub to my second hard drive.When I rebooted it went straight to windows.So I have some questions. When installing to the secondary HDD does my boot partition and swap need to be on sda? or can they reside on sdb?Also I tried to re-issue the grub-install command and it said bash: command not found. How can I get grub to re-install? I tried to emerge it and same issue no command found.Do I need to redo the entire reinstall?My last question is If I have more then enough HDD space how much is too much for linux? Most people say 30 GB is all you need from what I have read but I assume 160 GB is going to go to waste?
View 3 Replies View RelatedWhat is the most efficient way to match the partition tables on two different hard disks?
I have saved the partition tables using dd command in linux.
The partition tables are from a Windows system.
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!
I accidentially overwrote the first 1M of my harddisk on linux (using dd). So, the partition-table is gone. I can still access all partition (except the first one) using /dev/sda2 (and so on), so the data is still there. I only need the partition boundaries to restore the table. How can I do this? The Linux-Kernel must still know them because all mount-points still work. fdisk -l /dev/sda doesn't work because it acctualy reads the partition table.

There is a Wubi like installer for Puppy Linux. There is Debian Win32 installer, but I think that does touch the partition table. My last option is to simply grab Ubuntu 10.04 LTS and hope it works. Would that be a viable solution considering my needs?

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?
View 2 Replies View RelatedIs 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?
View 2 Replies View RelatedI'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).
i used to have ubuntu 9.i decided to move to sabayon so i used the live cd to install it ,resize the ubuntu partition and use the remaining space for sabayon.while the resizing procedure i got an error(i dont have a copy of the error log file but i know it has something to do with an anaconda process).i aborted the installation and the result was an filesystem that couldnt be mounted.when i try to mount the hdd i get this:
Code: Error mounting: mount: wrong fs type, bad option, bad superblock on /dev/sdb1,
missing codepage or helper program, or other error
In some cases useful info is found in syslog - try
dmesg | tail or so and this is what i get from fsck: Code: $ sudo fsck -f /dev/sdb1
code....
What I believe has happened is that I've corrupted the partition table. Essentially one of my partitions' ending point exceeds the maximum number of cylinders/sectors on my drive.
Essentially I have the same problem as on the thread @ [url] but do not know how to fix this and am afraid to reformat/partition based on sectors without really knowing what I'm doing here.
