Ah yes, ye olde Zip drive problem! I too, have a 3400c and 100mb Zip module and indeed it does work fine under OS 8.6 as you mentioned, - perhaps because the Iomega drivers originally accompanying that 100mb Zip module are fairly concurrent with 8.6's place in time. How well does 9.2.2 actually run for you on the 3400c? Not that it's entirely conclusive, but my understanding was that the 3400c can't really support anything past OS 9.0.4, maybe 9.1. I wouldn't have dreamed of trying to run 9.2.2 on a 3400c, but that's just me.
I also went back to 8.6 on the 3400c for specific apps & peripheral reasons, but because I experienced a whole ration of issues on my Pismo with OS 9.2 and its subtle design-for-link-to-OS X difference, I went back to 9.1 on the Pismo to keep everything working as it had for many years and still does, including a 250mb Zip module. I would suspect that 9.2.2 in its relationship to the specific Iomega driver isn't compatible at that level and be part of the problem. What Iomega driver version(s) have you used/tried? There are so many. I've got pretty much every variant of Zip drives: 100mb & 250mb, modules and externals, SCSI and USB, AC powered and bus-powered. Iomega is maddening and too often late to the party! But it sure was a big change from floppies!
Yeah, how about those days of the classic Mac OS? There was a time long long ago when we all understood what every file on the machine was and what it was for.
