As a free hand-me-out, I use this command generally...:

dd bs=512 if=/dev/rdisk0s3 of=/some_dir/foo.dmg conv=noerror,sync

The if=/dev/rdisk should correspond to either your partition or your disk and the of path should match your destination file.

Hi all,

Maybe not MacOS related, but I'm looking how to clone an entire

device drive drive, regardless filesystems on it, I need to

"simply" make two hard drive equals, if have read about 'dd' command

but is a bit hard to understand the options...

in my opinion should be:

dd if=sourceDrive of=targetDrive conv=notrunc

for source and target should I use 'disk' or 'rdisk' ?

can anyone help me or know where to read further docs?

dd has a man page. You can also google for more info. It works the

same on OS X as any *nix.

If you're looking to clone the entire device, including all partition

tables and filesystems on the disk, use the rdisk device. You'll

probably want it unmounted.
