In this example, I am going to clone /dev/ada0 (250G) to /dev/adb0 (250G) in FreeBSD and make an image using dd. # dd if=/dev/sdc of=/dev/sdd bs=64K conv=noerror,sync To clone /dev/sdc (250G) to /dev/sdd (250G) in Linux, enter:
The syntax is as follow to make disk image with dd:ĭd if=/dev/input/DEVICE-HERE of=/dev/OUTPUT/DEVICE-HERE bs=64K conv=noerror,sync However, if you have multiple disks, it is possible to do it online. Typically we boot from a live USB or DVD and create disk images. Remember the input file order ( if=) and output file ( of=). You should be very careful when using the dd command it can destroy data. The nixCraft or author is not responsible for data loss.
