CentOS 5 :: Mount Bsd/386 Partition To Recover Data
Jul 4, 2009
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.
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.
In a nutshell, our RAID 1 array was rendered broken and we were advised that core lib files were missing and the OS needed to be reloaded... a quote from our server host:"The OS is not healthy.This server will need a reinstall. Libs are missing." This was after having replaced what we though was a faulty /dev/sdb. So they reloaded the OS (Debian 5.0.2 x86_64) on 2 FRESH drives, and installed the old /dev/sda as /dev/sdc once the reload was completed. Here's the output of /etc/fstab on the fresh install so we know what we're working with:
The one problem I see myself running into is /dev/md1 and /dev/md2 are currently in use by the new system, so I cannot mount it there. I should also note, reloading the OS is a viable option if needed as we haven't started configuring the server yet. So if we need to reinstall the OS and assign the NEW RAID arrays to something other than /dev/md1 and /dev/md2 then we can do that.
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?
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 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 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 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?
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.
is there a way to recover data from a hd partition type fat32...cause ...cause right now it shows up as unallocated space..earlier i tried installing windows in a unused partition located just above this partition....i need to recover the data real soon...
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.
I 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
[code]....
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).
By mistake I formatted an ext3 partition on my external hard-drive. Now it has turned into a vfat filesystem. Is their any chance of recovering the lost data?
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)

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 need to recover some data of the 'home' directory after kernel panic.I was upgrading ubuntu 11.04, [COLOR=blue !important][COLOR=blue !important]installed[/COLOR][/COLOR] on usb.Failed to upgrade because the main partition had no more space. I moved one directory of about 100Mb to other partition, but it seemed that in the main partition didn't appear those 100Mb free. i restarted the computer expecting those 100Mb free. And kernel panic.

I have a 250 GB external disk, where there was store a hundred and something GB of data. Pictures, music, documents and TV-shows. It was FAT32. In an attemt to make an live USB drive with openSUSE, I did exactly what I shoulden't do: I mistook the external disk for the the USB drive. Now the external disk has a 700 mb linux partition, while 232.2 GB is unpartitioned. TestDisk from CGSecurity is looking to see if there is a lost partition table there, somewhere. Is there anything I can do? There was no formating, so the data is still there (except for those 650 mb that was overwritten). Is there any way to rebuild the old partition?
Output from "fdisk -l":

My main partition having all my data like movies, music, files,etc has become inaccessible. Its file system was NTFS. Due to some recent resizing using GParted, the partition as well as my WIndows 7 OS has become unbootable due to some errors. The data partition's file system has become unknown. I don't care much about the OS but I would like to recover my drive. I am trying to achieve this using Testdisk and Photorec but haven't met with much success so far. The main problem is I can see my partition and all my files through Testdisk but I am not able to copy them to another drive. When I try to copy the option I get is of copying them to the DVD and not to any other partition.
I am facing a serious problem.I installed UBUNTU 10.04 and encrypted it during installation. I accidentally erased some of the necessary files from root folder. now the the OS is NOT booting.luckily i still have the encryption key i have some important documents in that drive (desktop folder).
PS: I have tried to run Live Ubuntu it shows the Root, but it does not enter any of the folder.
Original disk: XP NTFS primary Linux / ext4 logical Linux /home ext4 logical Win 7 NTFS logical NTFS data logical swap space NTFS recovery partition
I tried to install linux, as there was a problem with XP overwriting grub, I chose write grub to /dev/sda8 (which is where the linux install was appearing earlier).
I guess this borked the filesystem somehow. Now the NTFS data partition and the swap space are appearing as one free space. Well actually before that some linux live CDs (including gparted were seeing the entire drive as unpartitioned). I had to go into XP and delete the /ext4 partitions.
Is there any way for me to recover the NTFS data partition ?
The situation: computer based on Asus P6T motherboard. Two RAIDS:
- 'boot', on motherboard built-in RAID controller (CentOS 5.5 installed on this RAID) - 'data' on 3dware RAID card
At one moment a CPU fan fails and the system halts. After the fan is replaced, BIOS informs it's reset and all the inner controller data are forgotten. After I switch it to 'RAID' mode, it remembers it was a mirror raid (RAID 1) installed, but the file system on it is completely trashed.
The 'data' RAID run by external controller isn't affected by the system failure. Three questions:
- is it worth trying to install OS on the rebuilt 'boot' RAID once again? Looks like if BIOS settings are lost for some reason, there's chance of completely losing RAID data - has someone encountered similar problem with built-in RAID nd was it possible to recover data? - will the software RAID be worth creating instead of using hardware RAID to replace the 'boot' drive?
I am using CentOS 5.5.I suppose this is an oft repeated question. I accidentally deleted, using rm command, 2 wmv files. The files were in a single ext3 1Tb drive, with just 1 partition --- the ext3 one. Each file is 600 - 800mb. The 1Tb drive has only about 20Gb data.Immediately after deleting the files i unmounted the drive (/dev/sdc1). Thereafter i searched the the net and came to know of the recovery tools foremost and photorec. I have installed both of them. I am currently running both of them as root --- foremost is just showing a lot of * signs on the terminal and photorec has managed to find some txt and png files --- but no wmv.For foremost i used: /usr/sbin/foremost -t wmv -i /dev/sdc1For photorec i followed some instructions available on the web.
In the meantime, based on some post on the net i ran debugfs as root, then cd into the directory where the files were deleted. Then on typing ls -d i managed to get the inodes of the 2 deleted files and the names of the deleted files are also correct. The instructions on the net http://www.theavidcoder.com/?p=3 tell me to run fsstat and dls both of which i am unable to find in /bin, /usr/bin, /usr/sbin and /sbin. So i am unable to proceed further.
After re-installing cups to deal with a printer problem, now I'm suddenly getting the message "Unable to mount Windows NTFS", which has all my data on it.
I'm trying to recover a GFS2 partition on a SAN that was connected to a server that was recently kickstarted with the "clearpart -all -initlabel". Is this possible? The volumes are quite large (20TB). I'm currently in the process of using parted's rescue feature but so far that has been unsuccessful.
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.
I just installed F13 x86_64 on a system that used to be running Windows 7.
The boot drive is a SATA drive attached to the motherboard which is working fine.
However, my data drive is an NTFS partition filling a 3.6TB SATA raid.
It's GPT--Gparted sees 3 unknown partitions, and gdisk shows:
Code:
How do I mount this in Fedora 13? I had intended to shrink the NTFS partition so that I can create an ext4 partition to move the data to. Will this be possible?
I've got a LOT of valuable data on this drive, and nothing else big enough to store it.
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?
I created an ext3 partition to be able to share data or files between CentOS 5.3 and F11 (and possibly other distros...) on /dev/sda5. I created the folder under /mnt and edited fstab and it's mounting ok and it lets me write to the drive.
But it's only seeing the files I wrote to it in F11, not the files or folders I created in CentOS; not even the text files created in gedit. I read some messages on here, and made myself the owner of the folder (data2share) and rebooted and it's still not seeing the files.
Might it be because F11 is using ext4 and CentOS is using ext3 ?? To test that theory, I started my external usb drive that's also formatted ext3 and it's seeing those files just fine. So I'm stumped.
