    How do I recover data from a hard drive that has been install with fedora 10, should I slave it on another fedora pc. I failed to rescue it with Fedora DVD but there is information I need to retrieve from this harddrive. What are the procedures steps to take

    You can do this with a Live-CD, e.g. Knoppix.

    When you click on these partitions, do they get mounted?

    Yes, the one with the information I want is mounted. Only the /boot folder is the one that I can see on the desktop icon (/boot) whether with the knoppix or with it as a slaved on the other computer

    Reading all physical volumes. this may take a while...
    Found a duplicate PV q3w4dbmVkgn85qqC2Scqk9b5kqboVMGJ using /dev/sdc2 not dev/sdb1

    Found volume group "VolGroup" using metadata type lvm2
    Found volume group "VolGroup" using metadata type lvm2

    my data may be wrapped in the logical volumes of which cannot retrieve

    Now am able to go to the command prompt, if i use code locate (folder name) i can see the folder path. How do I copy these folder to external harddrive, the external harddrive is /dev/sdd1 and the data i want to retrieve is on disk /dev/sda. When i used cp /dev/sda1/home/Administrator/User Data/Info /dev/sdd1/New Folder.
    I am getting this error message cp:target '/dev/sdd1/New folder' is not a directory.

    How do I copy the home directory files to the usb external drive

    You must mount the source and target hard drives first with the mount command, e.g. as follows:

    Code:
    mkdir /mnt/sda1
    mkdir /mnt/sdd1
    mount /dev/sda1 /mnt/sda1
    mount /dev/sdd1 /mnt/sdd1
    Afterwards you can copy files from /mnt/sda1 to /mnt/sdd1.

    when i entered the above codes had this error messages:
    [email protected]]# mkdir /mnts/sda1
    mkdir:cannot create directory '/mnt/sda1': Read-only file system
    [email protected]]# mkdir /mnts/usb
    mkdir:cannot create directory '/mnt/usb': Read-only file system
    [email protected]]# mkdir /dev/sdd1
    mkdir:cannot create directory '/dev/sdd1': Read-only file system

    then the mount code return that the mount /mnt/sda1 does not exist.
    What should I do to have the /dev/sdd1 and sda1 the write access or to get rid of this "Read-only file system" so that I can create a directory

    Try to mount it in another directory, e.g.
    Code:
    mkdir /home/sda1
    mount /dev/sda1 /home/sda1

    I managed to copy data to the external harddrive after I entered the this code mkfs -t ext3 /dev/sdd1, I boot using System rescueCD. I used the photorec tool to recover data. On the data i had recovered files with extension .txt, .max and doc are not openning. Infact all my word documents are not openning, is there an tool to recover text documents, on the system resueCD. All pictures, jpg,bmp have been recovered without problems.

    What should I use to recover text documents and saved email, my System rescueCD version is 1.2.0
