DATA RECOVERY IS NOT FUN.
If you've been sent here, you probably need to get some data restored. There are a number of methods for recovery, but one of the more effective, though pricey, options is to use a sophisticated drive recovery process in a "clean room".
We recommend DriveSavers, based in Novato, CA. They've been around for decades, have sophisticated equipment that can carefully extract data from extremely damaged computers. And they only charge you if they are successfully able to recover your data. And they do repair estimates at no cost to you.
This option worth trying if you feel (or if a consultant has explained) that simpler recovery techniques aren't working.
