Hi sn1peruk, and welcome to the forum.
From the number of posts you have asking questions I can only assume you are in dire need of the manual.
I would suggest putting in a request to join this Yahoo user's forum. It's an invaluable source of data and user's knowledge.
http://launch.groups.yahoo.com/group/emax/Once you've joined you have access to downloading the manual, files and sound files as well.
Are you using the Zip drive now with the Emax II? be sure the ID is set for, I believe 5 for the scsi zip drive. Using the Master menu follow the steps prompted in the menu and go ahead and format a blank zip disk.(In the Master menu it will prompt you..floppy? or ?
