I have a new p.c. (ASUS A7V133 motherboard with 1.4GHz AMD Athlon processor and 512k RAM and CD-ROM). The internal IDE ZIP 100 drive would not work properly with this system. Experienced huge delays in backing up or copying files. I changed from IDE to external USB ZIP 100 drive. I can now use the Iomega tools and back-up software only if I am logged on as the Administrator. If I log on as a Power-user, the Iomega software cannot locate the drive and I can only use the drive as a normal hard-drive and consequently I cannot use Iomega backup in this mode. I cannot install the IOMEGA detection software as a Power-user. I have tried all the usual Properties for the drive and USB connections, etc. in Harware Manager but no amount of enables and disables fixes the problem. Any Ideas?
