You don't say, I don't think, how the SCSI ZIP is connected. However, I am assuming you have the CrossDOS in L and the ZP0: ( say ) in Devs and you have used a text editor to edit the tool/icon for the ZP0: (or ZIP for the PC disk ) for the correct file system ie CrossDOS and set the unit number and SCSI device name. When you put the disk in the Amiga will try to mount the drive as an Amiga drive or a PC drive so you may have two mounted ZIP icons in Devs: , one say ZP0 for PC and one ZP1 for Amiga. You can call em what you like given that is the mount list the Amiga reads. Bit like DF1, DF2, DF3, CD0 etc etc. So interogate the tool/icon with an editor ( I use CED) and edit to suit the SCSI device, Unit number which if I recall for a ZIP drive is always 4 and then change the L to the CrossDOS file system.
PS if you lable your ZIPS as a hard drive like IHD0 then you have to lable every disk the same if you want to mount as a kinda hard drive. I never could get the 250MB ones working.
