Help with drives

I lost my cd burner for my dps12 the other day and my zip drive for the 2kxl is going. Can I get a hard drive that'll work with both the dps and mpc? Or are they different formats? I couldn't find this using the search, so sorry if this has been adressed, just post me a link to the proper forum.
Thanks!

theres a list of the compatible drives for the dps12 here
