You're talking about two really old machines, the 450 from 1998 & the 7025 from 2000. Both are about the same class, but I'd give the edge to Ricoh since it was also sold under a number of other brands & replacement parts are readily available. Hope this helps...
You have to have all the firmware in order to able to do that. It comes on a PCMCIA card that you plug into the copier. If you format the hard drive, there will be no way of getting the programs back unless you have that card.
There tough to get but I found a few of the cards on EBAY. Once you get that, then it's a matter of getting a hold of the software (if it isn't on the card already).
