Recovering file after CHKDSK

CHKDSK removed a text file containing C++ code from my hard drive while I was rebooting.  A binary .chk file was saved, but this file is virtually unusable.  Is there any way I can at least partially recover some of the information in this file?  Any help would GREATLY appreciated, as I do not enjoy the prospect of rewriting this file- and yes, I know how foolish I am for not backing it up!!

When CHKDSK creates a .chk from a text or ascii-type file, you can usually salvage much of the file my simply editing all of the .chk generated and simply copy the undamaged parts to a clipboard then paste it (or piece it) back into your application.  This is the only thing you can do since the actual file is now fragmented.  Your lucky that is a binary file -- it's the only type of file that you can actually salvage from the .chk file.

Once a file is deleted it is pretty much gone (unless you use a third party undelete utility), and unfortunately you can't undo a chkdsk to go backwards with the .chk file.

Thanks for the comments.  After closer inspection of the .chk file, I now realize that it is the object code which my compiler generated for the missing .cpp file (My system crashed in the middle of a build).  I realize this question may now be outside the scope of the NT-General area, but does anyone have any suggestions as to how I could "decompile" the object file to recover some of the source.  If I could even get a skeleton of what I had before, it would be helpful.  Thanks again.

You can disassemble an executable file into an assembly language approximation of the original code. You can then reconstruct your highlevel language code.
