What sort of data are you wanting to get back?
You could try just mounting the image in something like XWays Forensics/WinHex or another similar tool and see if will parse the file system. Otherwise if you want to carve for particular files, QPhotoRec does a good job with media files, or GetDataBack Free is also not bad.
If you just want to look at the raw data, WinHex, HxD or any hex editor of your choice will do.
