Mono corrupted D files

[AsmMan via Digitalmars-d]

Something very strange happened 2/3 days ago. Two of my D files 
of the project I was working on got all values replaced by 0 
(that's what I seen rather D code if I open the file with a hex 
debugger). The file size of both files keep intact although. And 
no, I have no backup of these files. I had a old copy of it on a 
external hard drive but I needed to format it to use in something 
else and didn't put my files before it...

Instead of turn off my windows machine I always hirbenate it and 
left open all stuff and then I just back quickly to point where I 
was on. That day, when I logged on system I noticied first 
non-usual behavior: the machine looked like I had restarted it 
instead of hibernate. All stuff I left open (including mono) 
wasn't open anymore. I find it strage but moved on. But to my 
surprise when I open mono, the "recent projects" always available 
on left menu bar was empty. Just like I had installed mono not 
used yet. I open my project directly by clicking on "open" and 
navigating to folder of projec and then I see the two of main 
project files with a values set to zero.

Can some Mono expected help me?
My question is: can I recovery these files? or what remains to me 
is cry?
restore the system didn't helped (and I neither expected to but I 
tried)

Not sure if it is related: that day my machine had no a network 
connection.
