Folks, Recently upgraded from Millennium to XP Pro. Also installed the XP version of NOD32. Almost everything on my machine survived the transistion except for my poor old Zip 100 parallel port drive. For a while after bootup the Zip can be accessed in normal fashion. Then, later, for no apparent reason, an access attempt results in a long delay and ends with the drive thinking there is no disk in it. Manually ejecting the disk and reinserting it allows normal access again . . . but only for a while. Exchanged several emails with the Iomega support folks, but their recommendations did nothing for me. On a hunch I disabled NOD32 and found that doing so cures the Zip drive problem, but obviously running without my favorite AV product is not desirable. Any suggestions out there?
