Nothing at all - except the difference between the 7935 and the 7933 is that 
the former has user-replacable disc packs. The same packs are used in the
7933, but they aren't user-replacable :-(
My sources tell me there WAS an upgrade option to turn a 7933 into a 7935
( :-) ?) but this cost about $4,000 ( :-( ) and may no longer be available.
If this is a viable option for you and you need to use replaceable packs,
I'd suggest you contact your local HP support office for more details.
