Good Afternoon

Does anyone know of good tape util programs for windows and unix.

For unix some of the actions come built in with programs such as dd.

Is there a tape reading program on windows that can do things like dd.

On both windows and unix is there a  program that  will look at the contents of 
a tape and guess what the tape has recorded on it. Like the tapemap program  
from the 
University of Kentucky.
                      
Thanks for any help with this
