Ubuntu :: How To Recover Data From 10.10
Jun 8, 2011
I've been using Ubuntu 10.10 on my EEE-PC for most of my thesis research, but I left it running a python script overnight and now I can't get it to login. I was running low on disk-space, and I think the problem is that the script generated a lot of text files and used up all of the available hard drive space.
Now, whenever I try to boot the machine, it reaches the user-select/login screen, but logging in just causes it to go black for a second before returning to the login screen. I have Ubuntu 11.04 on a USB, and Ubuntu Rescue Remix on another, and both allow me to boot up my machine, but I can't see my hard-drive - neither in /mnt/ nor in /media/ - in order to copy my thesis files or to delete some excess text files to free up some hard-drive space.

I'm browsing on my phone which is not letting me scroll to the end of this text box so I will say thank you in advance for any replies now.After my computer was switched off abruptly after a power outage I have many errors upon booting. My hard drive setup consists of a RAID0 array of two 500GB sata disks. The partition table (from my head!) goes like this:50GB NTFS Windows XP /c/50GB ext4 Ubuntu 9.10 /4GB swapThe rest is a large NTFS partition all the way up to the end of the array at 987GB. Mounted at /media/share/I am thinking I will have to start again (I won't lose much, I have recent backups), but what is the best way of restoring the system as much as I can? Currently my computer has been booted into Ubuntu for over an hour, and after pressing ctrl+alt+shift+F2 I can see that it is finding errors still, now at sector 6008. Should I let this run its course or REISUB it and boot onto a live CD. I think the main problem is with an NTFS partition

Well, my laptop slid off my couch and crashed down onto hardwood floor. The hard drive is shot. I was using grub and had both ubuntu 10.10 and windows 7 on it. Can't load either OS.
What options do I have for trying to recover data off the ubuntu partition? I tried loading livecd...for some reason, it won't work. Does livecd require a working harddisk?

When I installed Ubuntu, it created a folder called 'ubuntu' on my hard drive. Is there a way to recover my data from this folder and use it with a newer version of ubuntu. I can't access Ubuntu on my computer. It boots straight into Windows.

I have a full Ubuntu 9.10x64 install on an external hard drive and I was recently asked by a friend who has a laptop running 32 bit vista if I might be able to help him in recovering anything from pictures to Quick Books files. He believes the hard drive is corrupted. His laptop is an HP with less than 2 gigs of ram, and he is not sure about the motherboard/chipset. It may or may not support x64. He went out and bought an iMac the other day so he wouldn't need to deal with not having a working computer.
Now I have 2 questions. The first being, I am wondering if my x64 install will still be able to run if I tried booting to it from his computer in the event that the chipset that does not support 64 bit architecture, or do I need to revert to a 32 bit install? My instinct/what I perceive to be the obvious answer, is that yes, my x64 install should/will be able to boot via the bios. My second question is: how do I go about loading Ubuntu once the external is plugged into the iMac?

It seems my 320gb HDD has bitten the dust. The timing couldn't be more ironic as I have spent a couple of days tidying the files on it to burn them to disk.
This is an ntfs drive that had indicated 4 bad sectors but up until today (backup day) was fine. I am unable to mount it and in fact it is causing some sort of conflict with the OS drive and wont let the system boot up successfully.
I am going to try using a windows based PC tomorrow to see if I can rescue the data.
Are there any 'other' tricks to try and mount it with ubuntu that I may not have tried so far? I have tried-
mkdir /media/disk
fdisk -l to establish it's name which was /dev/sdb1 when it was all working but it isn't reachable and doesn't show in the places menu or in any of the menus when using a live CD to get round the HDD clash.
sudo mount -a used in desperation after the mkdir but nothing.
I rejigged the cabling inside the PC to make the HDD a secondary master as it was a slave on the primary IDE to start with in the hope that the system would boot up normally but to no avail.

I inadvertently started creating a boot disk over an entire 300GB external hard drive. Needless to say, I had all sorts of data saved on there. I stopped it early on in the process by turning off the drive, but I now I don't know how to salvage what's left.

I installed windows 7 over an existing xp partition and windows 7 made a 100 mb partition as some sort of windows swap space thing. This basically made my ubuntu partition unreadable, even with gparted. How to recover this data?

I was editing a PHP file by FTP on my Ubuntu server, and for some reason it's saved an empty file. Is there any chance I could get the contents back? If not, I'll just have to revert to an older backup

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.

so, after long time of succesfull use of kubuntu, i encountered a 1st major disaster yesterday while using kphotoalbum. It has somehow frozen my machine in so mighty way, that it apparently corrupted a directory with majority of my pictures , which now appears to be empty .My home lies on a separate partition, its encrypted aand using btrfs and I am using kubuntu 10.10. So, could anyone give me some clues how to unencrypt my home partition, that i could obtain an image of partition or whatever else usable for photorec to check for pictures?

I have a 1Tb Western Digital Network drive. I was showing someone the photos on this on their XP computer and noticed that each file also had a capitalized version beside. I assumed this was a copying mistake and highlighted all the capitalized copies and deleted them. To my horror all files have vansihed. The next horror came in that XP apparently doesn't move deleted files to the recycle bin it just deletes them. I rapidly went back to my ubuntu machine and mounted the network drive. However none of my normal recovery file methods work on network drives. PhotoRec doesn't list the drive. and sudo ddrescue -r 3 ~/.gvfs/SFTP for [myname] on [address]/[path] ~/LOGFILE tells me permission is denied.

I have a DVD-R labeled 16x that has been written by me in several sessions (but perhaps only one), always with an iso9660 fs, using a DVD writer whose data are these:
Vendor_info : 'LITE-ON '
Identifikation : 'DVDRW LH-20A1H '
Revision : 'LL0D'
Device seems to be: Generic mmc2 DVD-R/DVD-RW/DVD-RAM.
kernel 2.6.21.5, GNU (Slackware 12.0).
In spite of the last line, the drive is DVD+R compliant too. This is the only DVD drive I have and it seems unable to read that medium. Other discs, it reads them well. Before kissing the disc good bye, I would like to try all possible procedures at my disposal. The disc, by visual inspection, seems to be in a pristine condition. When I insert it, the drive remains with the led turned on for about one minute. I tried 'cdrecord -setdropts driveropts=singlesession dev=x,x,x' to switch the drive to single session mode but with no results. I have many tools in the cdrtools package:
cdrtools:
FILE LIST:
./
usr/
usr/bin/
usr/bin/skel
usr/bin/mkzftree
usr/bin/devdump
usr/bin/scgcheck
usr/bin/mkisofs
usr/bin/btcflash
usr/bin/isovfy
usr/bin/readcd
usr/bin/isodebug
usr/bin/cdda2wav
usr/bin/cdrecord
usr/bin/isodump
usr/bin/isoinfo
I also have dvd+rw-tools.

I just want one last attempt at seeing if there's a solution. My Dell Studio 15 laptop HDD that runs Vista failed, I booted Ubuntu from a CD knowing that I should be able to recover my data.
However, Ubuntu can't find my HDD, it's not listed and "fdisk -l" doesn't result in anything. The BIOS seems to know that the HDD is there though.

120 GB HDD. All ext4. Wanted to partition it into 60 gig ntfs, and 60 gig ext4 for dual install. Booted up the LiveCD. Clicked on the partition to modify. Selected /windows as mount point. Change took place. Now, my disk shows up as 57 GB FAT (almost all of which is free) and 60 GB of unallocated space. Any way to recover it? I'm sue the data is in the 60 GB of unallocated space. While I have a back up of some of the data, I'm going to be losing quite a bit if I can't recover this...

Recently I was forced to hard reset my computer a couple of times (mostly out of frustration) and due to my idiocy i was confronted with the standard Kernel Panic message at bootup. I tried running an fsck from live cd which corrected a bunch of errors but to no avail (as far as getting rid of the Kernel Panic msg). I then tried to mount the filesystem by accessing it from live cd (and later even installed ubuntu on a small leftover partition to get rid of the annoying live cd lag) but it says that I don't have access to my home or root folder. Mounting from command line gave the same issue.
So now to the question. Is there a general procedure to access data in my corrupt filesystem if it is encrypted?

I bought a new dell studio 1555 from best buy about a year and a half ago. Got the warranty because I have 4 kids and something is bound to be dropped, spilled or smashed at some point. True to my visions, something did get dropped smashed and spilled, and pennies got stuck in the dvd slot. So I took it in when the screen stopped coming on because of a loose connection in the hinge and they did apparently fix that problem, but also were benevolent enough to wipe out my entire hard drive, operating sytem and all, totally free of charge. I guess they figured since I like accidents so much, I would just LOVE having 18 months of data and programs disappear into thin air. I know all about how I should have backed it up, and I am not whining too much over this. I will roll with the punches. But there are just a FEW things on that hard drive I will really miss. Like a few crucial spreadsheets that I was not able to save to my external drive before the screen went south. Now that windows 7, I am not planning on missing at all. In fact I am loving running my new Ubuntu 11.04 from my usb and knowing that those idiots will not be able to screw this one up next time. But I would really like to be able to recover those files if I can. Is there any way to get those back? And I also cannot figure out how to find device manager. Do I have to install to hard drive to use that? I know these are all probably total newbie questions. But hey, i got here as soon as I could. Everybody has got to start somewhere.

I wanted to upgrade from Intrepid to Jaunty. I opted for a format/reinstall as I figured upgrading usually sucks. To save my important data, I resized my partition (partition A), formatted the empty space with ext3 (now partition B), and moved the necessary files from partition A to partition B. Then I went through the install process and installed Jaunty on partition A, telling the installer to NOT format partition B. It gave a warning about the installer deleting system folders (var, usr, etc) but I figured it didn't apply. I was wrong.
So now partition B is "empty." I know it didn't format it, but I need to get those files off of there. I have created an image of partition B using ddrescue, but I don't know where to go from there. I tried using foremost, but it won't recover things like my virtual machines and completely nukes the original file structure I had. And I've tried mounting it (using sudo mount -t ext3 -o loop /home/user/recovery.img /mnt), but that doesn't seem to work. The mount command completes successfully, but nothing shows up in the folder I mounted it to.

Because a customer of mine is inefficient in doing backups I have to do a recovery if possible. Drive had vista on it and was really bug infested to point of a reload. I reloaded vista from scratch and then my customer says "Oh, I guess I forgot to back those files up...".Is it possible to recover some files even though vista was reloaded? I suppose the basic answer is "As long as they havent been overwritten yet".
Im running testdisk and its made a ton of directories with files in them that I assume it has recovered. Im going to have to write a script I guess to grab the files as there are about 600 directories!I guess what Im asking is 1. What are my chances of success? 2. Has anyone ever recovered files from a vista re-install? 3. Is testdisk the best way of going about it (with photorec).

My friend has a DELL DIMENSION 9150 computer with 2 harddisk (250 GB each) in RAID 0 (fake raid) with Windows XP installed. There are a lot of documents and pictures installed - and no backup ever done! I have found some pages regarding recovery data from RAID 0 () but My friend have bought 2 new harddisks(WESTERN DIGITAL 2500AAJS) which is almost the same as the ones inside.
My plan:
1. copy each harddisk
2. replace original HDDs with my copies
3. try to recover
4. change RAID 0 to normal HDD in BIOS
5. reinstall Windows XP
I have some LINUX distros (DSL, SystemRescCD, UltimateBootCD on Live-CD and UBUNTU installed on one other computer) which I can use. I read about "dmraid" and then try to mounting the RAID in a UBUNTU live-CD version...

I wanted to get some data off a second disk, let me tell you what I did. (that didn't work). The data I am looking for is under /etc/ on the second disk. I looked in /dev for /dev/hda or hdb but there was nothing.
I found:
/dev/sda
/dev/sda1
/dev/sda2
/dev/sdb
/dev/sdb1
/dev/sdb2
So I guessed /dev/sdb /dev/sdb1 /dev/sdb2 was the second disk. So I did:
mkdir /tmp/olddisksdb
mkdir /tmp/olddisksdb1
mkdir /tmp/olddisksdb2
Then I did
mount /dev/sdb /tmp/olddisksdb and got mount: you must specify the filesystem type
mount /dev/sdb1 /tmp/olddisksdb1 and got no feedback (good?)
mount /dev/sdb2 /tmp/olddisksdb2 and got mount: you must specify the filesystem type
If I do:
ls /tmp/olddisksdb - I get nothing.
ls /tmp/olddisksdb2 - I get nothing
ls /tmp/olddisksdb1 - I get:
config-2.6.18-128.el5 symvers-2.6.18-128.el5.gz
config-2.6.18-164.9.1.el5 symvers-2.6.18-164.9.1.el5.gz

During a new installation of openSuse 11.2, because of a mistake, I lost access to previous partitions.
I was advised to use testdisk/testimage, but of course it didn't work, because my lost data had beeen encrypted.
How can I make linux ask me the previous root password?
I think any program that doesn't ask the previous password, isn't able to recover data. Is it true?
