I have 3 drives in my computer. I installed Fedora 11 on my two biggest one, with the LVM treating them as one single drive. I attempted to install XP on my last drive. As I was installing, I selected my third drive (I'm 100% sure it is the correct drive as it is an 80gb whilst the others are 120 and 200 respectively) and told it to delete the partition on that drive and format. After I did that, it started to format, starting with my 120! I'm fairly sure that it was merely a quick format, as it only took 5-10 seconds for it to format, and that my data is still there. Is there any way to recover my "lost" data, or did I just really screw myself over?

It's been a while since I configured a raid and have been making some changes to my main workstation/server.
fdisk does not like md devices on my machine... always says it has an invalid partition table. While this is said to be normal all over the net, I don't feel warm and fuzzy about that fact. What is best practice these days, to create a non-partitionable md device or a partitionable mdp device?
If I create a partitionable md device, I would imagine it would look good in fdisk. However, I am concerned about growing the array afterward. I would then have to grow the array, redefine the partition, and then grow the file system. The PITA factor goes up. Has anyone worked with both? Pro/Cons? My array was created with:
mdadm --create --verbose /dev/md0 --level=5 --force --raid-devices=3 /dev/sda1 /dev/sdb1 /dev/sdc1
FYI: I have backups. I understand RAID 1 may be a better choice of raid level.

I was running OpenSuse and realized that I hated it. I backed up my bookmarks to a USB flash drive, formatted and installed Ubuntu 10.04.
On entering Ubuntu, I stuck the USB flash drive in and realized that the bookmarks never got copied. I've lost them. I have to have those bookmarks. What would be the best way to get them back?

I did not find the solution to my problem reading other posts so I apologize in advance if this question has been solved in a previous thread.I recently started having input/output errors when trying to access directories on my external HD. Today I moved the content of my external HD to a single directory before starting a backup. Since then I can not access this backup directory anymore although the external HD automatically mounts when I turn it on.
I tried my luck starting the external HD in Windows but it wont show up in the explorer. What should I do to be able to mount it in windows and is there any way this would fix the problem?I'm running xubuntu kernel v 2.6.27-14-generic and the external HD is an acomdata.

I just installed kubuntu 10.10, replacing an older installation. I have three hard drives one of which had all of the data I wanted to save, about 500gb. I repartitioned and formatted the other two drives and made sure that the data drive would be mounted but not formatted. When I booted into my new installation, the data drive was blank. I'm not sure if it's relevant, but I had just upgraded the file system from ext2 to ext4 before starting the installation.
I've been trying to recover my lost partition with testdisk. The website has instructions for recovering a formatted partition. It looks like it's working until the instructions tell me to choose Boot and RebuildBS, which I don't see as options. Can anyone give me any advice on how to recover? How did this even happen? Has anyone had a similar issue with installation?

I am new to ubuntu. I was on windows 7 32 bit, computer was running slow with viruses and full hard drive so i installed ubuntu 10.10 32 bit as i believe it to be more secure. Before installing Ubuntu OS I made a backup DVD-RW data disk, it had my brothers holiday pics when he went turkey and morroco. Once I installed ubuntu I needed a DVD-RW and quick formatted the wrong disk. Is it possible to recover the data? I've read somewhere that the data is possibly can be recover.

I backed up my windows hard drive using dd and turned it into one huge image file. I didn't realize this beforehand, but this image is not an ISO equivalent type. However, it would be nice if I could access everything on the image just by mounting it instead of having to transfer it back to /dev/sda or something.

I have a laptop with Fedora 12 on it and I accidentally did an dd if=/dev/zero of=/dev/sda (since then I learned to think before I type)
anyway, I stopped it in time (I hope), it only zeroed first 60 MB. So, it killed partition table and boot partition. What I need is home partition, and it should be untouched. home is on a LVM device (fedora default install settings), and I tried testdisk (supposedly handles LVM) but it found only one partition (I guess it's a LVM physical device, as there should be 3 partitions, /, /home and swap) and said it's not recoverable.
Is there a way to get access to files on that partition (partition itself, including file table should be untouched). Partition contains various data (video, audio, and text) I need back (and it's my data, not backed up, and not something I can redownload). Is there any software that can help me with this, and if not, is it theoretically doable (I believe it should be, as the partition itself is not damaged, so it should be possible to read file names and link them with data on disk, am I right)? what is a good way to image the disk, so I can reinstall the laptop while trying to rescue data from image?

I accidentally formatted a 2TB drive of mine (big oops), but have recovered 2 of the 3 partitions using testdisk. My third partition is a LUKS encrypted partition. Testdisk managed to recover a piece of it, but it won't mount as most of it is unallocated. The partition originally occupied all space from sector 2,930,272,065 to the end of the disk -- sector 3,907,024,064. That is about 473 GBs. Currently, the partition only uses space from sector 2,930,272,065 to 2,930,288,129, about 7.84 MB.
The rest of the space is unallocated. Now what I need to do, is to expand the partition so that it occupies all the space that it used to. How would I do this? I cannot resize the partition, cause it would try to recreate the filesystem AFAIK and I don't want that, as it will fry my data. My data is not terribly important, but I would rather have it then not. I attached a screenie of kpartitionmanager. The partition in question is /dev/sdb2.

As usual I was notified that there was an update available via the Update Manager which I duly accepted.I was then confronted with a popup which advised that there was a Distribution Upgrade and that it was to be a partial upgrade.
Finding that I would not go away I accepted the data finding that 9 packages were made available and 33 unused ones were to be deleted. As this is my first experience of this is it something I need worry about and if so what should I do about it?

Last night I made the mistake of formatting my media drive. Before the format, it was ext4. then I formatted it to ext4 again because I wasn't paying attention to what I was doing(this mistake only gets made once). Now im looking for away to recover any/all of my data. The drive in question is 1tb. I have not written any new files to this drive.

After trying without success change from windows to ubuntu (dual-boot unsolved problems), I decided to try slack as I have seen that user to user support for slack is usually best oriented and faster.But I am having some problems in order to install slack because of GPT support. As I know its a bad idea to start to asking for help without speak what I have tried, lets to this first:
At first I tried just to boot from DVD and went through the install using the help inside the disk. It doesn't work because either fdisk and cfdisk that are suggested in help doesn't offer support to GPT.
After that first try i looked to:url
But also it suggest the use of fdisk. However, it suggested too that I could use another partition application and since I have the live cd for ubuntu, I tried to partition from there and use those partitions for installation.
At first I tried to format as ext4, but i discovered that slack still dont offer support to this format (at least the version that I downloaded).So I tried again but this time using ext3 as format to my / and /home and use the swap offered in the application for use as swap (duh!)But every time I try to install using the dvd it doesnt find my partitions with fdisk, only with the parted command I can see my partition table displayed correctly.However, every time I try to run setup it say that it didnt found and linux partition (swap also when i try to target).So this is my dilemma, I cant use fdisk, in the parted manual (url) it only says that it supports ext2 (not mention ext3) and also i dont find any command to use with parted to mark the partition as 82.I ran through this 2 other posts (url), but as I am still waiting for some update there I decided to ask it here hoping to discover that this is an easy problem.

I have installed Suse on my Windows Vista 64bit machine a couple of times, but the last time I did it - after a disk change - presented some unanticipated problems. Prior to install, Windows Disk Management (whose output I was unable to paste into this question) showed that my disks were laid out as follows:
[Code].....
Disk 0 is a Seagate ATA drive, while Disk 1 is a Western Digital Ext HDD Usb Device. Looking back, I think I should have carved out a partition after M before installing Suse, but I was uncertain whether to make it a logical one or a primary, and in the past the installation has taken the 25 or so gig it needed from the last defined partition on disk 0. This time, however, it went after disk 1, and reformatted the entire drive, deleting about 300 gig of user data, including my system backup. What really suprised me is that it took up the entire drive: 2 gig for the swapfile, then a 20 gig partition, and all the rest for the third partition.
This is not what I would have expected. I especially would not have expected the installation to re-format user data. In any case, I did not want Suse on disk 1, so I reformatted the drive and then used my Partition Manager to rebuild the boot Mbr. So now, I am able to boot into windows, do not have Suse on my machine, but have lost critical data. My disks are now back to the way they were when I started (see above), except that drive F is now all free space, except for my latest backup. My question is how do I ensure, when I reinstall Suse, that it will choose disk0 for the installation and will not overlay any of the data that I have on that drive.

I am trying to execute command mactime in order to control changes made to the file system, but I am getting an error. I am running the shell as root, and it is the first time I run the command in this system - Debian Squeeze up to date. The I/O is as follows:

I have recently installed ubuntu 10.04 aside to my windows 7. One thing I tried out was to share firefox and thunderbird profiles. I have a separate NTFS partition for sharing stuff.Everything seemed to work fine. I had all my browsing history and bookmarks and emails shared nicely between windows and ubuntu. But now I have managed to lost data twice already (in one week time). The data itself is not so important (no need to recover it). But I'm just curious, why is this failing?
I use firefox ProfileManager (firefox -ProfileManager) to create a new profile. I did it in Ubuntu. I created a new folder on my Share partition and pointed profile there. Everything works fine. Profile is saved there and I can use it in Ubuntu. Now, after I shut down Ubuntu and go into Windows 7 (which was hibernated the whole time), the given folder is gone. And in Ubuntu, the folder is also gone.There are some other folders, which I created during my Ubuntu session, which are not visible in Windows, but are visible in Ubuntu.Does any one have any suggestions, how to make sharing data possible? Or why is my data getting lost.

I was a regular Windows user and have installed Ubuntu 10.04 LTS 2 days back. Not really sure what was my mistake during installation but that had erased all my data. I lost windows completely and lost all my data in all 4 drives including drives itself.I searched in internet and forums as how could I recover my data, and got solution to use test disk. Testdisk worked perfectly, I recovered my 4 drives and retrieved data for 2 of my drives. But I still cann't retrive my important data from other drives.I guess data still exists in hard disk. (no free space , and no data)I know there could be several threads which had solved this kind of problem.

So I am working on a clients PC, and after I saved their data on an external hard drive I left it plugged in while I reinstalled Windows for them.....I HATE Windows. Stupid OS doesnt know any better than to just go deleting everything. Ubuntu would have known better than to delete multiple hard drives like that.
Anyway, please tell me I can salvage this data for my client? It was probably just reformatted. The data should still be there right?

I have a problem I don't know how to solve. Today I bought a netbook and while waiting for the new Ubuntu Unity release to come out, I thought of trying out Crunchbang instead of Windows that came with it. Browsing on my Ubuntu desktop machine, I found a guide for making Crunchbang live USB stick, and i followed the procedure. However, I made a very stupid mistake. The guide said I should enter the command:
sudo dd if=/path/to/iso/crunchbang-10-alpha-01-openbox-i686.iso of=/dev/sdX bs=4M;sync
where "of=...." part should be replaced with the name of the HDD. I forgot that I have an external HDD mounted and mistakenly copied the data to it.
After this, I cannot see the content of my external HDD anymore. Instead, i have this 620mb large Crunchbang-install device.
I know what I did was stupid, but is there a way to get the content of my HDD back? I have some valuable data on it.

You'd think that with two backups of all my data, which are syncronised twice weekly - that I'd be pretty safe. Fine and good until in a reorganisation of my documents folders,I delete a bunch of files - and don't notice until after I've run the backup - so they're deleted from the backups as well. Cue me beating myself around the head with the keyboard a few times about a week later when I realised.I'd advise against doing that if you have a keyboard like the IBM Model-M - it hurts.Okay, so I figure it's at least worth having a stab at recovering this data. The external harddrive's not had anything written to it since then, so is probably the best candidate. It's formatted as an NTFS volume (1.5Tb).
Now, I DO have a copy of R-Studio for Windows which I bought and paid for a few years agowhen XP managed to destroy itself and the file structure on the harddrive when it fell over installing SP2 (this was the event which lead ultimately to me switching to Ubuntu).I've found this to work quite well, though the initial scan does take a while.nfortunately, it does NOT seem to work from within Ubuntu through Wine. It runs, but can't see any drives. The only Windows environment I have access to now is Vista, andR-Studio seems to hang after running for an hour or so under Vista.
Are there any tools - preferably simple enough that I can get my head around them - which I can use from within Ubuntu to have a scrub through an NTFS drive to look for and otentially recover deleted data? I've found several tools which claim to recover things from ext3/4 drives from Windows - but not the other way around!There are a fair selection of filetypes involved here, some word documents, probably most of interest to me though are some old videos, mostly <5Mb taken on my old phone camera from university. Nothing really mission critical...but memories nevertheless.
