Corrupt Filesystem HD Recovery Issues

October 18th, 2013

Recently I have been working on trying to recover data off of my old external drive that was on its last leg. The drive has all of my personal documents on it from the last 10ish years, and the back up i had of the drive was stolen a few months ago.
So i attempted to use Disk Utility (DU) in osx as well as disk warrior, data recovery 3, super duper, and a few other programs that have helped me take baby steps toward data recovery.
The drive is now dead, but I was able to make a full clone of the drive with data recovery 3. The issue I have here is when i try to mount the HD clone.dmg I get a message telling me ” the following disk images couldn’t be opened image – HD Clone.dmg reason – no mountable file systems”. The no mountable file systems part is the same failure reason i could not get the dead drive to mount in DU. So this leaves me to believe that because the drive was formatted to HFS+ and has a/few bad sectors in the filesystem this is what hinders my data recovery.
I have tried to convert the dmg to a dmg with a read/write image format, but i get an input/output error (I/O) before the process can be competed.
So this is kind of where i am stuck and not sure what the next best option is for recovery. I was thinking about attempting to use Synchronize! pro x 6.3 but i am unable to find a working serial number.
Info:
I’m on my mbp running current version of osx lion.
the drive was 500gb, so the dmg that does not want to mount is also 500gb
I have another external that is 2tb, so i have enough space and workspaces to continue with any actions that are recommended.
If anyone has any idea on what i should do next, your help is greatly appreciated.
Let me know if you need any more information as well.
Thanks,

I don’t know if I read your post right or not, but if you are trying to open/extract a .dmg file (to access your files), then you could try 7zip, providing your image file is ok it will open it for you, allowing you to extract what you need. I have never used the mac version, but the windows version works well…..
