diskdump (dd) on Mac OS X Lion 10.7.2

Just a short notice:

After 2 month my MacBook Pro hard drive crashed. (its always good to have a backup 😉 ) I just got it back pre-installed.

To save this image I just entered “recovery mode” opened a Terminal and ….

… found “dd” ! This little tool helped  me to save the original hard drive image.

I connected an external drive and dumped disk0 on a file.

dd if=/dev/disk0 of=/Volumes/WDDrive/Lion_MAC_OS_X_PRE.img

It took about 15 minutes and it was Done !

I rebooted into Mac OS X Lion and zipped the image file.
