I use a program called "recover my files" that is pretty good and pretty cheep.

This would be if I deleted a file off my computer and then wanted it back.

Make sure you do this as soon as possible because deleting a file will allow that space to be reallocated.  Once that happens it is hard to recover.

Well, by the time you asked this question your data is likely gone unless you cut the power to the NAS immediately after realizing what you did.  (CUT power, not shut down properly).

Reason is that the internal file system of the NAS is most likely UNIX so that means the part of the disk drive that had the data is often the next area of the HDD that gets overwritten with new data.

If this data isn't worth thousands of dollars so you can pay a pro, then sorry, odds are it is gone forever.

Ameri: recover my files doesnt detect my NAS, do you know how to go about finding it?

dlethe: I havent written anything new to the NAS, do you think it's still gone for good?

It is a LINUX O/S that uses the XFS file system. So  you'll have to create a bootable USB stick with linux and make sure XFS is in the kernel ... then mount it read-only.

If you aren't a UNIX person, then don't even *think* of doing it, and even then you'll need somebody who can do a forensic discovery to find the file or at least chunks of it.

What is the filetype?  PDF, text, executable, .SQL ?   The filetype and size is vital.

you are totally screwed.  That file is going to be large and I guarantee at least parts of it have been overwritten.  But you could get a chunk of it with some commercial software.  You tell me, if you get 1/2 of it or all of it, but chucks of the file is full of zeros will this be of value?

If no, then you are screwed. if yes, please elaborate.

P.S. you HAVE written to the NAS.  The system is running an O/S, at least a dozen jobs are running in the background doing housekeeping and generating log files.
