Fedora :: Recovering Data From Password Encrypted Volume
Mar 4, 2010
I have installed fedora 11 in my system. While installing it asked me encrypted password which i passed. But I forgot that. Now the problem is whenever i boot my system before going to root itself it is asking for volume encrypted password, which as i told you i have forgot. Now i am not able to access my hard disk since it is completely locked. Is there any way to decrypt the password or unlock it. Or if that is not possible can data be recovered,which is my primary requirement..

I recently suffered a hard disk failure, meaning I had to replace the faulty device. After attempting to mount the old faulty hard drive using and external caddy, I got the following message... Unable to mount 144 GB Filesystem Error mounting: mount: wrong fs type, bad option, bad superblock on /dev/sdb5, missing codepage or helper program, or other error In some cases useful info is found in syslog - try dmesg | tail or so
I'd like to attempt to recover what I can from my /home directory but unfortunately I use encryption (although I do actually know my pass phrase). What procedures and software can I use to try and recover data from this drive?

I have recently recovered from an HDD failure on my Drobo. One of the disks died and corrupted the entire array (which is not supposed to happen). I have since managed to copy the data off onto smaller disks and after replacing the failed drive, have copied everything back.
Now that im up and running again, i was wondering how this situation would play out on encrypted disks, or in the case of a drobo a large encrypted partition (as you cannot encrypt the entire array).
Would i still be able to recover the data if i were to encrypt it? It is a 4.2TB array, and i assume that I would need to copy the data in its entirety to recover it, so using multiple smaller disks would be out of the question right?

I was trying to fix some hardware on my laptop and i ended up mucking the whole thing up. The HDD seems to fine though. I have it in a external HDD enclosure and it's plugged into my mothers desktop through usb.I'm trying to print some files I have, but my home directory on the external HDD is encrypted.

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.

I have been using fedora 12 for last 6 months, recently I bought an external USB hard drive of 320 GB capacity. I made 2 partitions using the Disk Utility in Fedora. I encrypted the first partition as it was supposed to hold a lot of sensitive data, and yes it did have. Now I had to change my OS to AV linux for some audio-video editing work which wasnt being done properly on fedora due to some issue beyond my knowledge. now the problem is my encrypted partition is not accessible in my new installation. I see an empty space on my /dev/sda1. although no change to partition data has been done and the data on the second partition /dev/sda2 is easily accessible. when putting the drive on automount, is does not ask me for the password and neither does it show me the data. I have tried fdisk and sme other utilities but have failed to get my drive unencrypted.

I started some months ago with Fedora 10, installed (on a barebones hardware package) from a DVD I got with a magazine. I liked it, and it worked fine. When 'Update Available' messages arrived, I installed the updates. When Fedora 11 arrived the same way, I installed that, a few weeks ago, and it, too, was working fine. A few days ago another 'Update Available' message arrived, and I installed it, unfortunately without backing up first. There was a message then that said to restart computer (which was still working fine).
I restarted the computer, and it would go as far as the moving blue bar across the bottom, then stop with a blinking cursor on a black screen. After trying several things, including the recovery part of the original DVD, I put a different, clean drive in the computer and reinstalled Fedora 10 from the original DVD. What I was hoping is that I could then install the original drive as a secondary one and get access to the files on it.

The following quote is the sad, sad story of a thumb drive with the partition table nuked, as told by a friend of mine:
Quote:
Data was recovered from an XP system by booting with a BartPC CD and copying onto a USB thumb drive. Nothing unusual.
System was rebooted into the XP install CD.
The first drive that was found was the 16gb thumb drive (AKA flash drive) and the person (re) installing XP didn't catch the fact that XP presented the 16gb thumb drive instead of the 160gb hard drive.
The drive partition function in XP deleted the partition table - on the thumb drive.
A freeware utility in Windows shows the data but can't recover the file names, so that everything is gobbledygook. Does anybody know of a utility or program under Linux that can help? I have a laptop running F 12 and can do the work if needed, but don't know what program to use.

I purchased a larger hard drive to upgrade my HTPC running MythTV and a Samba file server. I put the old hard drive into an e-SATA enclosure and can still boot to it to access my files, but I can't seem to mount it correctly under the new installation to copy over my files even though I have the mount passphrase and encrypted filenames key.I have tried using this howto, but I run into problems with the encrypted filenames.This is how I'm doing it. I replaced the actual key data with A's and B's to protect my keys:
Code:
$ sudo -i
# ecryptfs-add-passphrase --fnek

Let's begin from the top. I have a relatively new laptop that I've been running Ubuntu on (along with a little-used Windows boot). Picked it up in November or so, installed the current "latest" version of Ubuntu at the time (9.10). I have been doing incremental upgrades, and it's been progressively breaking down more and more. Yes, this includes 10.04.
After GRUB stopped working, I decided it was time to try a reinstall from the top. I told it to leave all the other operating systems alone and do a full reinstall.
Fortunately, I had managed to stuff most of my current work in duplicate locations during this whole debacle, somehow. Don't ask me how I managed to do that when GRUB wasn't working. However, when I installed, I conscientiously said "Oh, yes, Ubuntu, encrypt my home folder! I love privacy!" As a result, about... 30 gigabytes of useful (but ultimately re-downloadable) material is rather inaccessible at the moment. When I try to boot the old system using the newly fixed GRUB, it goes into kernel panic. This seems like a no-go.
I have a saved hojillion-character long passphrase for decryption from my install back in November. Conscientiously saved in the case of just such an emergency.
I read this how-to and followed it to the letter as far as I could tell, trying to mount with ecrytfs to recover my data.
[USERNAME] here is a proxy for my actual username. Yes, the location of my old home folder may seem a little bizarre.
Code:
sudo mount -t ecryptfs /media/c82ca9fe-2b15-4aca-a98d-6482b1d80a32/home/[USERNAME]/ /home/[USERNAME]/oldhome
Passphrase:
Select cipher:
1) aes: blocksize = 16; min keysize = 16; max keysize = 32 (not loaded)

I'm running Debian Squeeze AMD64 with full disk encryption and LVM. After reinstalling Windows 7 I lost GRUB from the MBR. I managed to install GRUB after following this guide and using an Ubuntu 10.04 graphical installation disc, but I only get to a GRUB CLI when booting, so I can't actually choose an OS there.
I tried following this guide but I'm stuck after "# Mount the partitions to /mnt/root" and don't know what to do.
Does anyone know how I can fix GRUB so I get to choose between Debian and Windows 7 there?

I need a FREE solution that can image an entire Luks system encrypted volume and the rest of the used HDD, the MBR and /boot partition. Note: MBR and /boot are not encrypted. Note 2: I want to be able to restore entire drive from image with only a couple of steps. Note 3: Destination HDD space is a factor. Image file must be compressed and the image file must be around 40 to 50 GB or less. The smaller the image the better.
I have used clonezilla live cd before but not for encrypted volumes. I know you can install it in Linux. But, I don't know how to configure it after installation. I would be very happy if someone could tell me how to configure clonezilla in Fedora. How to guides are also welcome. I have one more question. If I image the encrypted volumes and all the stuff I mentioned above while logged in to Fedora, and I restore the drive from the image, will the recovered drive still be encrypted?

I have F10 installed on my laptop with disk encryption enabled. When I boot the machine I get a "Password:" request on screen but can't start typing for 30 seconds or more.Presumably the OS is not ready. This means I have to wait at the keyboard tapping a key until I see asterix. It's a waste of time and frankly a bit clunky for a modern OS. How can I change the behaviour so that the "Password:" request only appears when I can actually type?

I made a mistake with lvm2 on centos 5.2.
I used parted to create a partition inside the logical volume, and then merrily used that partition, which appeared as /dev/pv-whatever/lv-whateverp1
Of course I created the FS as ext3.
So, after a reboot, I can't access anything in that logical volume with standard tools, as /dev/pv-whatever now only has the lv-whatever special file inside.
I can look inside the LV with parted fine, but parted can't copy ext3 filesystems.
Is there any way to get the data out of a partition created INSIDE a logical volume if that filesystem is ext3?

So I've pulled two hard drives out of my busted windows xp system (dead mb) and I'm trying to get some data off of them. The drives are in raid 0, so my friend told me that I might be able to do something if I use linux. Some late night searching on the internet directed me to a few resources, one of which was this forum. I've tried 2 methods, neither of which have worked.
1. mdadm
ubuntu@ubuntu:~$ sudo mdadm --detail /dev/sdb
mdadm: /dev/sdb does not appear to be an md device
2. dmraid
ubuntu@ubuntu:~$ sudo dmraid -s
/dev/sdb: "sil" and "hpt45x" formats discovered (using hpt45x)!
ERROR: sil: wrong # of devices in RAID set "sil_agafdhcebccj" [1/2] on /dev/sda
ERROR: removing inconsistent RAID set "sil_agafdhcebccj"
[code]....
I've got some files for work that I'd really like to get off there. I've played with unix a bit in college and I've ran ubuntu before, but usually using the GUI, so a lot of this stuff is over my head. But from what I gather, my system thinks that one of the drives isn't a raid drive?

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?

A few days ago I accidentally deleted a video file from the trash and I am looking forward to recover it but google could not give me a hand. Even worse I don't remember the name of the file.
Is there any specific free software for this? Or command line? (I am not good at it but can learn fast).

I've accidently begun installing Ubuntu Studio onto my OpenSUSE drive I stupidly forgot to to swap my hard drive cables around.
Luckily, the Ubuntu Studio install failed before I noticed the problem, but I need to access the SUSE drive to pull some date off of it. Whats the best way of doing this?
I used a program in windows XP to try and pull the data (mainly holiday snaps) off the drive, but it only works on NTFS file systems, so didn't get me what I need.
How can I access the data on the linux partitions? I'm fairly certain I was using 11.2, which after a bit of googling seems touse the EXT3 file format. Correct?
I'm in over my head here really, as you can probably tell, but what my limited knowledge leads me to believe is that the Ubuntu installer overwrote my partition table (is that right?) but left all the data there still.
Ideally I need a program very similar to the one that I used, but which works for the SUSE filesystem, and runs under XP (my only working OS at the moment)

A friend of mine somehow managed to accidentally format her USB key the other day. It had all the photos of her daughter on it and she's more than a little upset about it.
I've told her not to fret too much just yet and that I'll have a look to see if there's any way to recover any of the data (specifically the photo's, she's not overly fussed about the rest)
I've had a look through the web, and foremost looks like it's the most promising option but I don't want to start messing around with it until I've asked my fellow ubuntu users for advice and thoughts.

I have recently gotten hold of a device that helps me plug my old ATA/IDE hard drive to my computer and view my old files that I wish to recover. I am using Ubuntu and the harddrive that I wish to retrieve the data from also has an Ubuntu install on it. The files I wish to recover are old .doc files, which I want to keep to remember my old writings.
The problem I have encountered arises when I wish to open some of the files. The icon for some of the files, which happen to be my best writings, has an X on the top right, indicating that I cannot view the contents. When I click on the files, the following error message pops up: "Access to /media/c885571b-a6e5-4a2d-937a-78af7050910/george/Courses/hist388/Passion.doc was denied."
Now, I am guessing that I need to be able to log in as superuser or something to be able to access these files, so I logged in my terminal as super user by following the instructions outlined on this page: [url]
I still did not have the sufficient access required to be able to open the files that I would like to retrieve.

I've got 10.10 running trying to recover files from 10.04/10.10 I don't know what to call it. I did update-manager -d but all I get is a bunch of failed packages when I try to run it, so I downloaded the full RC iso. Now I'm trying to recover my stuff from the HD using a live-usb. The only problem is, when I try to copy the files onto my SD card, I do not have permission to access some of the stuff on the HD and some of the stuff like the "Desktop" I do.

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?

Since recently I have installed windows (dont worry I will be back to ubuntu soon enough but I've ran into some trouble), I had installed windows on my main hard disk (I couldn't install windows on my 2nd hard disk for some reason).
There were 2 partitions on the main hard disk, 1 which had all my data and another which had all the system fyles for ubuntu on it I believe.
Now I deleted the small system fyle partition and installed windows over it thinking I'd have all my data on the other partition when I needed.
But when I started up ubuntu with a live USB (I had made it prior to deinstalling ubuntu because I wanted to go back asap) and browsed my files, I noticed that I couldn't get to my private data anymore!
The /home/user partition is still there but it only has a file in it which says something like "recover-private-data.desktop" but when I double click it (made it executable) it just pops up a terminal real fast and disappears.
