Hi.  I have a drive from a Windows machine (NTFS) that I think may have 
some problems.  I'd like to make a copy to play with so I can leave the 
original undisturbed for now.  Is this what I should do?
   dd if=/dev/hdx of=/dev/hdy   # where x=original, y=copy

Along those lines, if I did the following
   dd if=/dev/hdx of=/path/to/image

would I be able to mount the image with something like?
   mount -o loop /path/to/image /mnt/mountpoint
