How is level 2 hard drive recovery done?

How is level 2 hard drive recovery done? I know alot of times the logic board is replaced or the platters are transferred in a clean room, but what if they can't find an identical hard drive? Is there a tool that can just read raw platters? If this said tool or machine exists, where do you buy one? If I wanted to start a professional hard drive recovery service what would I need (besides a clean room)?

Thanks

By the way, building a cleanroom is no small task !!

You need a minimum of a Class 100 clean room (max 100 0.5 micro particles per cubic foot; 70 degree F, 45% relative humidity) to safely work on a hard drive. This is a VERY clean room => you could not possibly achieve this with a vacuum cleaner; air filter; or any combination thereof in a normal room.

And even this is not nearly clean enough for some functions -- Intel's fabs, for example, use Class 10 cleanrooms (10 particles per cubic foot); and the stackers in the fabs (the machines that move the actual silicon chips) are maintained at Class 1 (!!). I had a tour of a fab a few years ago; and was told the air in the observation area (a hallway where you could look into the cleanroom) was "about Class 100,000". And THAT is still a very clean area. A typical room is MUCH, MUCH worse!!

Thanks for the info, that quick read was more informative than the last 3 days on the internet.

You're most welcome -- it's instructive to actually see one of the Intel facilities (no wonder they cost over a billion dollars to build).
