Without asking what is wrong with your existing "cd drive" and assuming the
following :-

#1 :- Existing "cd drive" is a CD burner.
#2 :- Replacement "cd drive" is a CD burner.
#3 :- You have a 'burning' software utility - e.g Nero, etc.,

then all should work fine - however, just to be doubly sure (belt & braces),
you should set a System Restore point BEFORE you start the work. That way,
you can always replace the 'different (replacement) cd drive' with the
'original cd drive' if all goes pear-shaped and recall the previous SR point
back to where you were before you started the work.

Would it mess up the system if i temporally put in a different cd drive to
burn a backup of the whole system
