oops, my bad. I answered for the disks when you meant the drives. I also think the same applies for the drives as well.
I have a NEC Zip 100 IDE in my system, but the bios recognizes is as an Iomega, even the firmware indicates it's IOMEGA.
So, although I am not sure, it seems that IOMEGA also manufactures the drives for NEC. Besides, I never had any problem with this drive, or my USB Zip. No Click of Death issues in the past 4 years I've owned it.
