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.

my /dev/sdb contains
2 partitions with fat 32
2 partitions with NTFS
1 partition with LINUX ext3
and a swap linux.
I did :
Code:
dd if=/dev/sdb of=image_disk_sdb.img
How can I mount those several partitions?
I have a HDD that I was using as temporary storage (ext4) though I knew it was close to failing. Upon retrieval of the data, I found some of it was corrupted.
I unmounted and ran gddrescue on the whole device (/dev/sdd) using this command:
Code:
The image took ~24 hours to complete, and I can mount it using:
Code:
Of course, some of the files are still slightly corrupted, so I would like to fsck on the image to try and correct anything that can be. However, when trying this on the image, I get:
Code:
Here are some other interesting pieces of info:
Code:
gpart finds no useful info it seems, and trying to fsck using the -b option and the backups suggested by mke2fs results in the message above or (using a very high block):
Code:
As I said, the image can be mounted and the filesystem accessed. Many of the files seem ok and can be directly copied off of the mount, but I'd like see if some can be recovered or at the very least copy everything off the image, skipping the corrupted files (perhaps with a log of those skipped).
None of the data is critical and will be ok if lost, but I'd still like to try recovering it just as a proof of concept. The original disk can still be used (very slowly), but I'd rather recover the data only using the image if possible.

I have 2 HDD in my PC . The 2nd one is a 1TB Western Digital Harddisk which was formatted in Win XP NTFS and just 1 partition, using it for archieve (Film- Music - Apps ... ). I was trying to use fdisk command , but unfortunately destroy the data , format and partition it like this picture :

recover my data . Any procedure or software ? By the wayy , I use Win Xp & Ubuntu 10.04 . According to the problem and the above picture in which OS should I recover my data - Ubuntu or WinXP ?
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?
I have an issue with a PC (XP pro)that had a virus which deleted all the files in the windows/system32/config folder. I first attempted to do the second repair option on the XP cd and it wasn't available. So unable to boot to windows and run an anti-virus; I put the hard drive in my external enclosure. Plugged it into my ubuntu laptop and removed the virus infected files using Clam. I then tried using the XP cd in the first repair to copy the files only to get an access denied msg.
I would like to just copy necessary data from the drive with XP pro installed and then reinstall XP and give the PC back to the owners. However the person that did the original install used a volume license cd and I unfortunately have no more CD keys and hate using cracks in certain business environments. So I came up with good idea at the time to setup XP pro in virtual box and then copy the files from there however those files are in use when the machine is running and can't be copied. So is there anyway to mount the Virtual hard drive and copy the files while the virtual machine is off?
I have a laptop dual booted with windows vista and ubuntu.I downloaded certain movies and music files while using windows vista,which are there in my hard disk,My question is can i access these music and video files when i boot into ubuntu,and can i play them?
View 5 Replies View RelatedI'm using ext3 and I have my / partition on sda3. This is a full install, it has /bin /home etc etc on it, the only thing I have is sda1 is /boot and sda2 is swap.
I've configured my system to mount sda4 as /home/user as the system boots up, which puts all of my data on sda4.
My question is this. How do I access any data left in (sda3) /home/user? (Because trying that won't work). Is there some way to use a direct path? Like /device/sda3/home/user?
We purchased a new database system at work last October, ditching the old system because of a lack of support from the vendor. This is a retail Point of Sale and Backoffice database system. I am not sure what system the new one runs on, but the system we replaced was a Firebird data base. The reason I am posting is because we are now in need of the information contained in the old database which was not completely imported into the new system. Unfortunately, we parted company with the old vendor under extremely hostile conditions, and they are not a source of help for this problem, nor are the new vendors.
Basically the problem is this: The database in on a Windows XP system and I found a copy of SQL Manager Lite 2008 on the system, which after quite a bit of studying, I figured out how to extract the database into a removable file. I have this file (178MB) on a USB stick in a file called Backoffice.fbd. I can get into this database with MySQL. All I want to be able to do get into the database and create tab deliminated spreadsheet files for each of the database sections (Customers, Repairs, Sales History, stock files, etc.) Is it possible to do this with Ubuntu and MySQL and if so, can an expert suggest one or two things to get me started.
I am running Ubuntu 10.04, and i recently purchased an tandberg LTO-4 SAS tape drive. I want to access it and backup data on it. Do I simply just connect plug it into the server,and I should be able to backup/transfer data to the tape drive? Or are there intermediate steps before I can do that.

I have written an application which has more than 6 threads.Two threads share a common linked list. Out of two threads one thread reads the linked list node and other thread writes to linked list node.I am using pthread_mutex_lock() API to achieve synchronisation between having access to common linked list. The problem is the first thread which reads the linked list accesses the mutex faster making other thread to starve.
I want both the thread to have an access to mutex. It should not happen that always first thread locks, releases and relocks it. The first thread almost require to access the link list every 5 msec which is causing second thread not to gain the mutex.How should I fix this? For information, I am running this application on PXA270 ARM platform.

View 14 Replies View RelatedI am using an embedded platform in which I have connected an external harddisk (/dev/sda). The SCSI driver is present and I am using the SG_IO interface for performing the SMART commands with the Hard Disk. (Unfortunately not all the HDIO ioclts are present. So I opted for the SG_IO ioctl). But the data transfer (reading/write data from/to sector) is not working with the SG_IO ioctls. So I searched for some other options. Later in one of the places, I found that we can actually mount the /dev/sda to some mount point in /mnt and then make a XFS file system (mkfs.xfs) of this.
And then we can create the directories and do file operations on this mounted directory. Here the simple read/write systems calls can be used for this. I was thinking about this implementation. But I am confused how I can map the actual LBA (Logical Block Address) to the device file offset. I mean if I want to write to the sector 5, there will be a LBA for it. So I can do lseek on my device and then write the data there. So how the mapping between LBA and device file offset can be calculated.

View 5 Replies View RelatedI have 2 RAID1 hard drives with possibly hardware errors, (when I tried to mount them in a degraded array, they won't start, throwing some Buffer I/O errors) So I used ddrescue to make a disk image out of one drive, ran losetup to use the image file as loopback device:
Code:
losetup /dev/loop0 imagefile.img
but when I tried to assemble a raid array including the /dev/loop0 device like:
Code:
mdadm --assemble /dev/md0 --force /dev/loop0
it will complain that no superblock is found on /dev/loop0 device. With desperation, I tried to create a legacy raid array with following command, of course, including one of the bad drives:
Code:
mdadm -B /dev/md0 --level=1 -n2 /dev/sdb1(bootable partition on the bad drive) /dev/loop0
I successfully created a new RAID1 array, but when I tried to mount it
[Code]....
Now the only thing I haven't tried is to clean the superblock by doing --zero-superblock, and not sure if that will solve the problem. Should I get a second drive to hold my broken drive image so that I might be able to assemble a good RAID1 array or should I continue working on the only disk image file I recovered from one of the broken drives?

View 3 Replies View RelatedSuppose I have a 80 GB hard disk (sda) with 4GB of contents. Using a dd to copy to a different disk
Code:
dd if=/dev/sda of=/dev/sdb
copies all the contents (including free space). So sdb also needs to be 80GB.
You will notice that in VMWare or VirtualBox disk images, it is possible to set the disk to use only the amount of space of actual data. So a 80GB virtualbox/vmware image with 4GB of contents will be 4GB.
Is it possible to do that with an actual hard disk (sda) image? I want to create an image of an actual hard disk, copy it to DVD and transport it (in mail) for restoration on another computer (having same hard disk).
I tried the Linux-based live CD's of the main Windows anti-virus vendors (Kaspersky, BitDefender, AVG, Avira). They work well, but they are single-purpose solutions while affected Windows users also need a solution to 1) pull data (or what's left of it) out of their contaminated Windows host onto a USB thumb drive or a remote host, and 2) restore a clean image using eg. CloneZilla. Asking users to burn and run three different CD's is not very user-friendly. Has someone already investigated combining those three features into a single live CD?
View 8 Replies View Relatedi'm wondering if it's possible to restore the original image file that you have hidden data in with steghide. The basic Idea is you have a photo using gpg sign it and then embed the signature. then remove the signature at a later time and check it with the signature. I hope another "inverse" algorithm doesn't need to be written to undo the first (if a "inverse algorithm is possible). This assume you already have the pass phrase or that there is no pass phrase. I already know how to retrieve the original file just want to remove the hidden data from the Image and restore it's attributes.

Some people recommend to extract the data via the dd command, but it didn't seem very safe for me to do that!

is it possible to extract the data into a directory (instead of a device) using dd? This file is supposed to be a software. I wanted to run it on wine by keeping it mounted on a mount point in my file system. Does it make any sense to try to do this if the file simply isn't a cd image?
I was testing a bug in F12+Acer Aspire One and its 'suspend' feature (you can probably find the thread) and I ended with my SDHC card messed up. I formatted it as ext2 (or ext3, don't remember exactly) and apparently its superblock got corrupted. For one thing there is a single file I want to recover from the card (I don't mind formatting it afterwards). I am no expert using e2fsck or fsck, that's why I am asking here. In addition I used the "dd" command to create a backup of the drive in a file (so I can start tinkering with it). What is the best course of action to recover my files? Either from the card or from the image?

Is it possible to mount a DD image to a device. If I can't do that I just want to extract the files to run some programs against the drive. Can I view the files under Ubuntu or do I have to remove the drive and stick it into a Vista computer.
I purchased a second drive today and was hoping the command line would be something simple.
