Oh well. Hopefully your situation will work out! I did try to mount the drive as an image, but the disc still had problems. Oh well. Hopefully your situation will work out!

Mac laptop HD crashed and is now unmountable. All recovery software; Disk warrior, Mac Utilities, Drive 10, Data Rescue, File Salvage, darwin filutil etc, don't work, can't see the drive. I am now working with dd command from the terminal prompt. It looks something like this: dd bs=512 if=/dev/rXX# of=/some_dir/foo.dmg conv=noerror,sync It basically allows you to save a target disk down to another drive as a huge dmg file. You then have the issue of how to mount the big-ass file so you can parse out your files. more details here: http://www.macosxhints.com/article.php?story=20050302225659382 I really think this is a clever approach that may become a key method of future recovery tools since dd just copies bytes not caring anything about what it is copying and if the sync command is used, it doesn't hang up on perceived errors. I still seem to be having some issues my hard drive which could mean some physical failure, but I still believe the dd approach is the most viable approach for situations where you have an unmountable drive that you need to recover data off of.
