Thought that this may be useful for people using G4U and have a need to
access files from a ghost image without having to restore the entire
image to a disk.
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 ntfs 192.168.51.13 /mnt/ntfs
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
