Re: I'm in deep trouble
First, don't do anything to those drives. If they are Data drives (No OS on them) then disconnect them.
Next, see if you have any type of malware and fix it.
Next, look for recovery software. It is important that you remove them from the equation first and fix whatever caused the problem.
Where are the files missing from? (Which drive)
What kinds of files? (Archival/Desktop/etc.)
Humans are the only creatures that won't live up to the their potential. Give everything your all. When you die, die on E.
So I ask you, what do you intend to do now?
