Yet another ZIP saving problem...

I have no problem loading my samples into the mpc via SCSI 100mb zip made from MPCEditor but when I try to save them the zip drive is constantly spinning and will not stop. I have tried three different zip drives(which I got brand new) along with brand new and used disks(Iomega,Fuji,Maxell). I have to send everything I've made straight to the Vegas right then or I'll lose them wether I'm finish making the beat or not. I have the termination switch on and the scsi ID to 5,all the connections are correct or I wouldn't be able to get anything off of them. The MPC keeps saying SCSI not ready and I'm sitting there pulling my dreads out. CAn someone come wit a solution becasue I just can't bear(but I might have to ) going back to mono samples using the floppies. I'm not high and mighty or nothing but when you get use to using huge full STEREO samples it's hard to go back to 1.44mb when now my songs use at 20mb's now. That might seem huge but when you run the sample through Sound forge and normalize and retweak them they sound DOPE AS H*LL it cuts down on mastering time, but anyway please someone guide me, I'll get a Externak HD if I have to but let's figure this out first if possible

I have the terminaton switch on and it's not set to ID 6....Is the MPC sending weird messages??...It only spins when I try to access it through the MPC after trying to save. I've hooked all three of the zip drives to another computer via SCSI and the save and load fine. Is my scsi on the mpc on the fritz....Oh I hae the old mpc2000 not XL and I have 1.72 OS so.......
