MPC 3000 Won't save Sound File to Zip Disk

Hey there, I recently acquired an MPC 3000 and a zip disk. I was able to format the disks and save a sequence and a program, however, when I go to save a program with sounds (Or just a .snd for that matter) I get the following error:
Sorry, this file (or possibly the entire disk) contains damaged data..........
The sound files were a handful of 1 sec drum hits.
Also I've tried a few different zip's thinking maybe the zip's were bad but it has happened on 4-5 different zips.

Any insight as to why this could be happening would be helpful.

Thanks

Definitely using ZIP 100. Also using OS 3.11. Sidenote: I was able to create a PGM with Sounds using RS-16x, save that to the zip and then load it. I could save changes to that program, record new samples to it and was even able to save it to a different partition on the ZIP. It's very bizarre.
