Searching you can find other members' comments about other tools they have tried.
But most important. Make sure you have a good handle on what you choose to do. In spite of many EU's and their poor practices they really do value their stuff. And some are willing to spend some money on getting it back. So if you have a customer like that then it is best you just find a qualified DR lab. If the customer does not care, and you have that in writing, then feel free to play around, at your own risk of course.
Some observations.
1. drives making funny noises, clicking, grinding, spinning up and down, etc will not yield any data.
2. opening the drive to fiddle with it will make it fail if you are not using a clean space.
3. it's very time consuming.
4. It's a great way to learn about file systems and their structures as well as general OS operations.
