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:
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:

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.
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).

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?
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...
Well i have an 20GB HDD (/dev/sdb) formated with ext4 and has very important files on it .All of sudden something went wrong and the 20GB partition has been lost . Now how do i have to recover that partition and primarily recover those files . Gparted shows no partition on it but unpartitioned space .
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:
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 bought an IcyBox NAS a little while back, and it recently died on me. I have physical access to the disks inside (1.5TB RAID 1 array), and the box was running a version of Linux. I now have the difficulty of retrieving the data from the disks. As best I can tell, the NAS uses software RAID. All I have available are 2 Windows machines, one of which has sufficient free space to hold the data from the NAS. I've booted one of the Windows machines into Linux using a Ubuntu CD, and Ubuntu can see the array drive(s), but cannot mount them.
What would be the quickest and easiest way to retrieve the data from the disks? What data can I collect from Ubuntu (10.10) that will help me pin down why it can't mount the array volume?
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 unknowingly formatted my whole 160GB hard disk to ext4 file system from Fat while installing Ubuntu. Now my hard disk has only one ext4 partition. recover my old data.
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 deleted an old ubuntu partition, I reinstalled Ubuntu but is there any software for Ubuntu or any other Linux operating systems that can recover my data?
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.
A HP Netserver LP2000r, with original SCSI controller and HP NetRaid-2M controller, 3x 36GB Ultra3 HDD in RAID5, Debian (sarge/etch), has crashed after 992 days without reboot. From all that I can see, a hardware failure, most likely with the memory. The HP Diagnostic tools cannot find any problem, but everytime I boot into Knoppix, I get between 2minutes and 2 hours of runtime, and then either a kernel oops or just a complete and sudden halt.
Well, the box has earned its money. However, there is some data on the drives that I need to recover (yes, I have beaten myself up properly about not backing up that data, don't even go there !). There are three partitions: sda1 is /, sda2 is swap and sda3 is a LVM volume with 3 logical volumes on it. As far as I can tell, the hardware defect must have been creeping in and has made a total mess of the inodes in all these partitions.
After booting into Knoppix, I can restore the volumes using pvscan, vgscan, lvscan, vgcfgrestore and vgchange. If I try and mount them: mayhem. So I try and check them, using fsck.ext3. All sorts of interesting nonsense, such as a completely empty inode 11 (the first inode) and then obviously from there on all else is pointless. I tried using debugfs, but the information on what to do with it is somewhat spurious.
P.S.: Tomorrow I will go and get myself a 16GB Flash Drive and then hopefully I will be able to dump the partitions one by one onto that drive and transfer the images onto a different computer for analysis and data recovery.
I was running CentOS 5 with VMware Server on top of it. The system died and I'm trying to recover the VM images. The system died with a 'end_request: I/O error, dev' type message. It looks to me like the 2nd partition is wonky - is that correct? The GRUB portion does boot. I pulled the drive out and plugged it into my Ubuntu box to see if could get to the files. I ran 'fdisk -l' and found:
To me this shows the GRUB boot partition and the system drive - correct? Next I created a mount point and tried 'mount /dev/sdb2 /mnt/recover' At that point I get a
mount: unknown filesystem type 'LVM2_member'
Here's where I'm a bit lost. I believe I need to add filesystem support to my Ubuntu box. I've been looking but have yet to find something that says the default filesystem of CentOS 5 is <blah>. After I do find that info, how do I install the filesytem support to read the drive?
I was using a Buffalo LinkStation Duo to store pictures and the OS in the unit failed. As far as I know, the data on the two 1 TB drives is fine, and since Buffalo uses a Linux kernel in their LinkStation and the format is xfs, it should be possible to get the data off if I can mount one of the drives on a Linux box. I've put one of the drives into an external USB enclosure and attached it to my Linux system, but I cannot get the drive to mount, probably because it is one element of a Raid 1 array.
Most of what I can find on the Web concerns setting up a new Raid array, not creating an array around a drive that already contains data. I have installed mdadm, and I'm running Mint Linux release 9 (Isadora) on an Intel box. When I run mdadm -D /dev/sdb or sdb6, the device and the partition where the data is located, it reports that the device does not appear to be an md device. I'm not sure what that means. Any help would be greatly appreciated, as I've got around 13,000 photos on these disks that have no backup (I figured what could go wrong with mirrored copies?).
I need to mount a bsd/386 partition on my hard drive to recover data. I am running the latest CentOS 5.3, downloaded and installed in the last week.My searches have turned up a mount command, that does not work.
[root@new-host-2 ~]# mount -t ufs -o fstype=444bsd /dev/sda3 /mnt/bsd mount: unknown filesystem type 'ufs' [root@new-host-2 ~]# mount /dev/sda3 /mnt/bsd
[code]...
So, is there a patch to get mount -t ufs working?is there a patch to get bsd/386 filesystem type? have not build a kernel before, so I would like to avoid that, but I will attempt it if I have no other options.
Using F12 with a LVM Volume, Single disk with OS on and boot partition. The OS HDD is getting i/o errors, but will still boot to the login screen. I've removed the HDD and connected it to a Fedora Live OS on my laptop, connected the HDD and it registers as :
[root@localhost]# fdisk -l /dev/sdd Disk /dev/sdd: 250.1 GB, 250059350016 bytes 255 heads, 63 sectors/track, 30401 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Disk identifier: 0x000e0069

And it tried to mount /dev/sdd2 to view and see if I can recover some files. [root@localhost]# mount /dev/sdd2 /mnt -t ext4[root@localhost james]# mount /dev/sdd2 /mnt -t ext4 mount: wrong fs type, bad option, bad superblock on /dev/sdd2, missing codepage or helper program, or other error In some cases useful info is found in syslog - try dmesg | tail or so
Any way to mount the partition to allow me to try and get some data back, or if trying to do a full backup of the drive you can get it to ignore i/o errors.
On my drive I had 2 partitions for an Ubuntu 9.04 (swap, /) and one partition for Windows. I figured out that I should upgrade my Ubuntu, so I deleted the "/" partition and in its place created 2 new partitions (/, /home) .
After installing the latest Ubuntu 11.04, I realised that although I had backuped everything I needed in a 2nd disk and I could access those folders and their data from my Ubuntu 9.04, both my Windows and the 11.04 can locate neither the folders nor the data now. I have no idea why this happened (perhaps some issue with the mounting?) I have tried the trial version of Stellar Phoenix linux data recovery tool, but it cannot locate the old partitions.
I tried to recover deleted data using testdisk tool and now my partition table have some errors. Even though i have 3 partitions and 1 unallocated disk fdisk -l shows only 1 partition
