Tools to Recover data from a damaged Hard Disk

---

Could you help me to find a good tools (commercial or freeware) that can help to recover some data from a Damaged HDD?
Sometimes we used testdisk to recover partition but mainly it works well to recover deleted files.
One friend told me that use that MacOS with a freeware tools(i have still to ask which tools)

He told me that, instead of Windows that sometimes it block itself when is passing through some broken cluster, MacOS go forward.....and even if at the end could say that was impossible to recover all, at least is possible to analyse the entire disk.

Any Advice??

My favorite is Ubuntu Live Boot. I have been doing this since 1982. I started with MFM and SCSI-I in MB size. Most of the hard drives that I find damaged are only damaged in the part that allows the drive to boot the OS. Usually I can mount these drives and get into the file system with Ubuntu Live Boot CD or USB. It only loads the OS in memory. If this doesn't work. On-Track in Minnesota is my next choice. Very pricey. If you need the family pictures from the drive, don't mess with it and cause more damage. Pay them.

This is from Steve Gibson of GRC and Security Now, if you do use it, let me know if it is successful. I hope this helps.

I have used Recuva (the free version) to successfully recover files, several times.
