Once your drive is connected, its time to start your machine and prepare a Zip disk for use. The Advanced Disk Utility (on a IIgs) or the utility that came with your SCSI card can do formatting and set up partitions (i.e. create named "Volumes"). Usually, with new for-PC Disks, just partitioning is required for use under ProDOS. Each 100MB disk can hold three max-size (32MB) ProDOS partitions. If your interface is a RamFAST rev. D 3.01f or later model, you will be able to treat Zip disks much like large floppies. They will mount and unmount properly in the GS Finder, etc.. Most other interface cards will want to treat your Zip Drive and disk like a hard disk. This is because the cards were designed before removable high- density R/W media became popular. You may be able to swap in a disk after booting; but, the new disk is likely to be treated as though it is the disk which was present during power-up. This could lead to messed-up partitions, lost files, and other problems. With such interface cards, the safe way to swap Zip disks is to turn OFF the computer. ---------------------------- 007-How does Zip Drive speed compare with a hard disk speed? Iomega claims 29ms average access time, which is slower than modern hard disks but, still, very speedy. ----------------------------
