I used a Kingston 8Gb flash drive as a live usb recently (copied the live iso image over using dd). I am done with the installations and all but seem to have a problem. i cannot format my flash drive. It now shows as a live CD (800 or so mb). Is there a way to fix the partition table back? I guess if i copy a partition table image from some other 8 gb drive that might fix the problem but i dont have any other flash drives. Is there a solution possible or am i stuck with a live usb forever

I am running a dual boot with Vista and Ubuntu. When I rebooted It will only go to the Grub> prompt. Ive ran TestDisk and though that I had corrected the problem but it didnt. After running TestDisk again here is what It came up with.

I have laptop with ubuntu on it. I have one ext3 partition with ~220GB.
I want to delete ubuntu and create two ntfs partitions (50+170GB) so i can install windows 7 later.
how to do that using GParted Live CD?
I am completely ubuntu right now, and I need to create a partition for XP without losing all the work I have on ubuntu. How can I shrink ubuntu's partition to make a 15 gb partition for XP without losing data?According to Gparted:
sda = ubuntu
sda2 = swap
sda3 = extended
I have a 160gb hard drive with no partitions. Ubuntu runs on the entire disc. I want to cut off 60gb from my file system as a storage drive without losing the data that i already have on it.
I don't want to reinstall Ubuntu and cannot afford to lose all my data. Is it possible to do so, without having to reinstall the OS.
I downloaded Gparted, whats next?
I was trying to remove the physical volume from an old drive. So I opened gparted and told it to rewrite the partition table. The only problem is I targeted the wrong volume, I wiped the partition table on my 4tb raid5 array This 4tb array has everything! All my movies, tv shows, music. The only things I have backup up off site are my smaller files like documents. I was about to lose my whole media collection.
I did some research and found a solution that I will post here in the hopes that someone will google "I deleted the partition table on my lvm" and be find the solution.You should find in your filesystem a /etc/lvm/backup folder. LVM puts a copy of the crucial lvm information there every time you change the the volume group.
In this folder you will find a file for each volume group. In this file you will find the uuid for all of the physical volumes that make up that group.The first step is to recreate each physical volume with their original uuids. In my case I had only 1 physical volume, which was my raid5 array. My recreation command looked like this:
pvcreate --uuid cLrY02-zrVi-D0Vi-cIPB-6fF5-ed0c-XFF0os /dev/md0
Now I have a physical volume with the same uuid it had before. It is essential that you correctly match up the uuids with the correct physical deviecs.The recreated pv is empty, the volume group needs to be recovered. This is done by using a special tool and the backup file. For me the command looked like this:
vgcfgrestore --file /etc/lvm/backup/raid5 raid5
This tells it to recreate the volume group using the information in the backup file. The backup files looks for the uuid of the PV, which now matches the correct volume. The coordinates in the backup file match up to the data on the array an suddenly everything is back!
When I deleted my LVM partition table I did not damage any of the actual volumes on the volume group, I just wiped out the table of contents. The backup file had the information needed to rewrite this table of contents.
I would like to resize my /home ( /dev/sdb6 ) partition - without losing data - to make room to create a swap partition (at the moment, I don't have any swap. Is it dangerous ?) IIRC, it was possible to change partition sizes from the install disk in repair mode (?) But I cannot find that repair mode on the 11.3 install disk. Has it been removed or is it somewhere deeper in the install or update process ?

Just ran into an uncomfortable problem. I usually never save any documents on my machine, and keep all my stuff on an external USB hard disk. (an 80GB TrekStor DS microdisk q.u)
Well yesterday this disk just would not mount.
Read through related posts but nothing seemed to work. Even tried it on a Windows machine.
Tried TestDisk utility. Found nothing wrong with the drive, but still could not repair the MBR.log code...
Palimpsest Utility recognized the drive, but just will not let me do anything with it except format it.
How can i repair the partitions and MBR without losing all my data?
had trouble viewing partition table using fdisk, now realised i just cudnt view the whole table from Rescue terminal, please remove this thread, i can't find how ))
View 1 Replies View RelatedI was putting the cover back on my Antec p180b, and I guess it got stuck and gave it a hard bump (pretty much broke the cover). As a result, one of my hard drives, a Seagate Barracuda ST3750640AS, got messed up or something. All the other hard drives are fine. It's in an LVM with another hard drive, so now I can't boot up into my computer. So I booted into the installation CD:
Code:
# find /dev/sd[a-c][1-3]
/dev/sda1
/dev/sda2

This led me to believe the partition was messed up. So I ran cfdisk, and it said something about a missing partition table or something. Additionally, instead of showing the single partition on it, it displays, from my recollection, Pri*Log. To my knowledge, this is the only problem with the hard drive. So now I need to either somehow create or restore the partition table without overwriting the data. Or get a new hard drive, and some how recover the data (LVM, partitions, and all).
I used to have a 1TB external drive with lots of stuff on it. But after a reported drive failure during a F11 install the partition table seems to have been lost. (I think F11 toasted it)
Disk /dev/sdc: 1000.2 GB, 1000215724032 bytes

The drive used to have xfs and a partition. Is there any way to rebuild the partition? Or is my 1TB of data gone forever? The drives seem to be fine now... I just want to get it up enough to either pull any data or just to get a file list. Most of the stuff on the drive was from somewhere else.(ie 300GB of NRN data for all of North America.
I was trying to delete a logical drive in windows xp and the damn disk management tool in windows not only deleted my other windows partition but also my linux /data ext3 partition. Now I have a unallocated space in place of these partitions. The data is still there but the entries in the partition table have been removed. So how do I recover my partition. I was trying to use the following tutorial. [URK]
I used the sudo parted /dev/sda -- and then rescue START END command and could get back the /data partition. But it gives me the following error while mounting the partition. mount: wrong fs type, bad option, bad superblock on /dev/sda7, missing codepage or helper program or other error. In some cases useful info is found in syslog - try dmesg | tail or so.
What does this mean. How to I fix this? Also when I try to recover my windows partition using parted it scans for a while and then does nothing. It doesnot ask for writing the lost partition in the partition table. What do I do?
I just made a very stupid mistake, and in result I just deleted almost everything on my windows 7 partition. I followed this guide: [URL].. for how to access my windows partition from ubuntu and it worked, but then I decided to rm -r the whole thing thinking it was a copy. I have no restore disks or any other type of backup. I know this maybe be impossible, but is there any way to recover my data?

View 2 Replies View RelatedSo the first 10Gb of a 450GB NTFS partition have just accidently been written over with an Ext4 filesystem that spans the entire partition instead. all foolishness asside, what can be repaired. Now I know Ext4 likes to jot bits of meta-data down (inodes blocks) along the way, and this can be about 5% of drive capacity, that said, there's alot of small text files and stuff, coe files so forth that can surely be recovered
I've looked into magicrescue and testdisk, but they fall into the only two groups to exist:
1) Filesystem independent, that is search almost like a patern - well exactly like a pattern match, to find the header and footer of files.
2) Filesystem recovery tools, like, damaged bootsector, so forth
I need one, that will be able to extract files, Iunderstand this will be a hard task, but.... text files; surely that'll be easy, anyway. This is my backup drive, they''re both WD you see, anyway. This is important, given the coding is ASCII surely.
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.
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?
