Check out www.macfixit.com. Lots of comments are recorded regarding Iomega's problems. The Iomega driver is incompatib
e with many USB devices, so one or the other must be disabled in the extensions folder. Iomega is working on a new vers
on of its driver.

Ah, ha. Just got to the crux of my matter. The new IMACs are being built
with USB connections ( Universal Serial Bus). Mac made a deliberate
decision to phase out old SCSI connections from IMACs ( which attach old
jaz and zIp drives), as SCSI is too sensitive to orders of connections in
daisy chain arrangements ( some devices only like to be last), and USB does
not have this problem. (ATA (or IDE) built in provide two connections in a
G4 for an internal CD drive, zip drive, the HD and one more item.) I can
still link old zip to my G4 and it works but my Iomega zip tools will not
find and fix zips in that drive as it refuses to see the zip. Any answers?>
