hfs

I had an HFS+ formatted drive that was going bad and wouldn't mount at all on OSX. I created an image using ddrescue on linux, and was able to save most of it.

I can mount the drive and see the data just fine in linux using this:

mount -o loop -t hfsplus dd_image mountpoint

This doesn't work on my OSX system since hfsplus isn't a valid filesystem type. If I try:

mount -t hfs image mountpoint

It complains that it needs a block device. What's the fix here?
