If your software does have such an option, you might want to try it since it could take forever to go through those bad blocks. Finding such options with your current software, since we know it works with MACs, would be my first choice. I am not a MAC guy, so I do not know that software Data Rescue 3, but I know that with software like Ghost 2003, you could use switches that would allow it to ignore bad blocks and continue on. If you can finish the clone of the drive, you have a decent shot at getting the data back. The reality is that your data may not, and very likely, is not necessarily in the area of the bad blocks base on the laws of probability. (Note: this is a mostly-copy of my answer to this earlier question.)įirst, if is highly unlikely that the drive is "completely composed of bad blocks", but if it is, your chances would not be very good. The account is the first line of text in their logo (case matters!) and the password is the second line of text in their logo (see the FAQ for an explanation). The important thing is that their download links require an account/password. There is ddrescue as a compiled binary for OS X on TinyApps. There's a procedure on for how to use it to recover a Mac's internal drive in your situation you'd just skip step 1 and use USB instead of FireWire in step 4. Using it will be a bit unintuitive on OS X, since it wants to work with the unix-level device file, not a mounted volume. You could also run filesystem repair tools on the recovered disk/image, but if you run anything that modifies the volume ( at all), you will not be able to continue the recovery (you'd have to restart from the beginning). If not, dismount it, unlock, and rerun ddrescue to see if it can get any more. You can even let it run for a while, then mount the recovered volume (it must be read-only - if it's an image file, just lock the file before mounting it) and see if your files are there. The longer you leave it running, the more data you'll get (unless the disk is completely unreadable). What ddrescue does is to copy the contents of the drive, skipping over any sections that don't read successfully then it goes back and retries the sections that got errors on the first pass. One possibility (a bit similar to suggestion) is to use ddrescue to clone it to either another drive (at least as large as the original) or to a disk image file.
