I got small problem. I need to make a mirror of a disk. Zero it and then restore data.
I'm using DD linux command to copy data to a file.
sudo dd if=/dev/sde of=/media/Rozne-new/hitachi_disk2.img bs=1M
The problem is, Harddisk is 250GB big, and ooutput is 15GB file.
First partition is 14GB (according to disk utility). All partitions on this disk are unmounted.
