OK, here's the deal. I need service done on my MBP, but would rather not give them the HDD content clear as day. My plan is the following: 1) Boot from a Linux USB stick that needs little more than samba or AFP mounting support and dd; mount my server and do "dd if=/dev/sdx of=/server/path/disk.image" 2) Wipe the disk and install Snow Leopard, in case they need to do testing in-OS. 3) Give them the computer. 4) When I get it back, boot from the USB stick again, reversing if= and of= to write the image to the disk. 5) Done, everything works exactly as before. Am I missing anything, or will this work? I'm mostly worried re: EFI, but I don't really see *why* it would cause problems. Thanks in advance.
