Thread: Mounting NTFS Drive Image, Offset Not Working?

    Post Mounting NTFS Drive Image, Offset Not Working?

    Hello,

    I have an image of an NTFS drive created with dd_rescue. The image was of the entire device, not just a partition. I am trying to mount this under Suse 11.1 using a loopback device and specifying the offset value.

    However, not matter what I try, I can not seem to make this work.

    When I actually go to mount it the mount command hangs interminably, or results in an error:

    Callandor:~ # Cannot create link /etc/mtab~
    Perhaps there is a stale lock file?

    Perhaps I am missing something easy here, but it seem darn neigh impossible to get this to actually work.

    I would really appreciate any suggestions anyone may have - I am about out of option.

    Cheers,

    Pete


    Callandor:~ # fdisk -lu /virtual/80GBNotebookDrive.dd.img
    You must set cylinders.
    You can do this from the extra functions menu.

    Disk /virtual/80GBNotebookDrive.dd.img: 0 MB, 0 bytes
    255 heads, 63 sectors/track, 0 cylinders, total 0 sectors
    Units = sectors of 1 * 512 = 512 bytes
    Disk identifier: 0x7ec87ec8

    Device Boot Start End Blocks Id System
    /virtual/80GBNotebookDrive.dd.img1 * 63 78124094 39062016 7 HPFS/NTFS


    Callandor:~ # losetup /dev/loop4 /virtual/80GBNotebookDrive.dd.img -o 32768
    Callandor:~ # file -s /dev/loop4
    /dev/loop4: Hitachi SH big-endian COFF object, not stripped

    Callandor:~ # losetup -o 32256 /dev/loop5 /virtual/80GBNotebookDrive.dd.img
    Callandor:~ # file -s /dev/loop5
    /dev/loop5: x86 boot sector


    Regardless of what offset I use, I get . . .

    Callandor:~ #mount -o loop,offset=32256 /virtual/80GBNotebookDrive.dd.img /mnt/image/

    Callandor:~ # Cannot create link /etc/mtab~
    Perhaps there is a stale lock file?

    What really runs . .

    Callandor:~ # ps aux | grep mount
    root 5702 0.0 0.0 2552 896 pts/2 S+ 17:18 0:00 mount -o loop,offset=32256 /virtual/80GBNotebookDrive.dd.img /mnt/image/
    root 5704 0.1 0.0 2596 1040 pts/2 S+ 17:18 0:00 /sbin/mount.ntfs /dev/loop0 /mnt/image/ -o rw,offset=32256
    root 5706 0.0 0.0 2544 768 pts/2 S+ 17:18 0:00 /bin/mount -i -f -t fuseblk -o rw,allow_other,blksize=4096 /dev/loop0 /mnt/image
    root 5708 0.0 0.0 2264 680 pts/3 S+ 17:18 0:00 grep mount

    I have also tried . . .

    Callandor:~ # losetup -o 32256 /dev/loop5 /virtual/80GBNotebookDrive.dd.img
    Callandor:~ # file -s /dev/loop5
    /dev/loop5: x86 boot sector
    Callandor:~ # mount -t ntfs /dev/loop5 /mnt/image/
    Cannot create link /etc/mtab~
    Perhaps there is a stale lock file?

    Thanks for the suggestion, I've never used the support mailing list - that is a great idea. I just sent off a message to it!
