Missing Folders

I've been retracing my recent steps, and I might have found the cause of my particular issue. I've recently learned of the Windows command "Robocopy", which is a very efficient, powerful and yes even dangerous file management tool.

I initially noted that the "/MIR" switch would mirror the complete directory structure of the source onto the destination. In re-researching the details of this command, I found these chilling details:

"The /MIR switch tells Robocopy you want to mirror the two folders, copying all folders (even empty ones) from the source directory and purging folders from the destination if they no longer exist on the source."

I'm going to assume (save some kind hearted generous Windows/Linux guru out there wishes to display pity upon my stupidity by helping me recover them through advanced magical wizardry), that my files are completely gone from the NAS.

Oh, and if this is indeed the reason for both of my incidents, then I sincerely apologize for thinking and speaking ill against Netgear and their ReadyNAS devices and software.
