tiggertie · 05-22-2010, 09:21 AM

have a disk image of a laptop in a DVD. the fdisk details is provided in a text file and it shows it has HDA1 as HPFS/NTFS partition. however after copying the content in a to a directory issued the following command to create a NTFS partition

dd if=/home/dvd2 of=/home/hda1.dd skip=0 bs=512 count=3824

however it retuns had1.dd as empty

pls. help

It would depend on how the image was created, if they imaged the whole disk eg:

dd if=dev/hda ...

then you should be able to just put it straight back:

dd if=/mnt/<dvd?>/image.dd of=/dev/hda bs=512

If it was an image of a specific partition, then you need to recreate the partitions first with fdisk or similar, then restore the image:

dd if=/mnt/<dvd?>/image.dd of=/dev/hda1 bs=512
