USB flash drives have no moving parts to cause problems and will prove to be more dependable over time, for long-term data storage. Just because your B&W G3 has an internal Zip drive (as does mine), I wouldn't recommend investing $$ in new disks. The zip or jaz drive icons will appear as a floppy icon. To reformat the drive use the Erase Disk option contained in the Mac OS Special pull down window. Now, the drives have become obsolete in terms of what they offer and what is available now. The SHIM driver relies on the Mac OS to support the drive rather than the Iomega tools utility.
In their prime (and before the advent of CD-R/RW drives), the Zip 100 and 250 drives were a convenient means of transferring a lot of large files from one computer to another. The scarcity factor is behind their greed in overpricing a 3-pack of Zip 100 disks. Why not use a USB flash drive instead? A sale-priced 4GB drive costs less than $10 now, and it has 40x the storage capacity of a single 100MB Zip disk - which are quite expensive now at most retail office supply stores. If you're considering buying new Zip disks, I assume that you want to transfer/store files. I deleted that program and INIT, after installing the IomegaWare. This may be the application in use that you mentioned. As I recall, the latter included an extra application & INIT in the Extensions folder (perhaps 'QuikSync'), which ran in the background. I should have suggested that you find/download the older IomegaWare 3.0.4 - which I preferred over the newer 4.0.2.
