FILE RECOVERY

[Ron Guilmet]

Hey all,
   
  I have a question that maybe someone can help me with.
   
  I setup FreeBSD on one of my spare pcs, and I am interested in file recovery.
   
  I have an used HDD that I want to install as a secondary (which I know how to do), but can someone point me in the right direction as to what I need to learn about FreeBSD to examine this spare drive for files?
   
  I have software that will do it in my windows pc, but I'm not really interested in what's on the drive as much as I am interested in how to work with this.
   
  thanks.
