It's hard to judge right? They ALL say the same things: We're the best,
if we cannot do it no one can, we have the best clean room, we have the

I gave an example of one recovery service, ACS, touting the expertise of
another one, Data Savers. They might be able to tell by telephoned
description whether or not they have the resources to perform the
recovery. Upon inspection, they should also tell you that. If they
cannot recover, there should be no charge. They may even recommend
someone else (who'll probably be more expensive to perform the more
complicated recovery).

Some places don't have a clean room or ferromagnetic microscopes. Like
the video that I showed, some just attempt exterior repair, like
replacing the PCB with those from matching donor drives and swapping the
ROM or microcontroller chip from the old to new PCB (if needed which is
not always a requirement).
