Hi Stefan,
It is possible to access the file inside the image but you just need
to be
able to mount them from another distro or Linux boot CD.
It is recommend that you have a recent Linux distro I used the latest
Ubuntu
as this has the latest fdisk and GNU file tools that support large
files. Knoppix or
other new distros should work just as well.
Mount the file share where you have stored your images.
I used NFS as SMB seems to have a max file-size limit of 2Gb on file-
share I was
using.
# mount -t nfs 192.168.51.13 /mnt/nfs
Uncompress the image but as a sparse file i.e. don't create the empty
space on the file-share server.
# gunzip -dc test_t43p.gz | cp --sparse=always /dev/stdin test_t43_outo
Next you need to find the partition offset's that are inside your
image as you
cannot mount the image file directly as the first blocks contain the
boot records and
other data.
# fdisk -l -u -C 592 <image_name>
Disk testo_t43_outo: 0 MB, 0 bytes
240 heads, 63 sectors/track, 592 cylinders, total 0 sectors
Units = sectors of 1 * 512 = 512 bytes
Device Boot Start End Blocks Id System
testo_t43_outo1 * 63 108939599 54469768+ 7 HPFS/NTFS
Partition 1 has different physical/logical endings:
phys=(1023, 239, 63) logical=(7204, 239, 63)
testo_t43_outo2 108939600 117210239 4135320 12 Compaq
diagnostics
Partition 2 has different physical/logical beginnings (non-Linux?):
phys=(1023, 0, 1) logical=(7205, 0, 1)
Partition 2 has different physical/logical endings:
phys=(1023, 239, 63) logical=(7751, 239, 63)
Multiply the start cylinder by 512 to get the offset in this case 32256
# mount -t ntfs -o loop,offset=32256,ro <image_name> /mnt/loop
Change the filesystem type if the disk is not NTFS i.e. EXT3 for Linux.

You now have access to all the files in the image.
