"I want to purchase a hard drive with 100+ gb of space, but I don't want to have to have to install any software in order to use it."
How do I answer this? An OS is still needed on most machines which we get to install. For some OSes, a driver is needed and on too many machines the USB 2.0 that you want is not supported without updates to the OS.

I don't think you'll find such an animal.
I want to purchase a hard drive with 100+ gb of space, but I don't want to have to have to install any software in order to use it.
I will mainly be using it with macs, and on the apple site I found the smartdisk firelite, an 80gb for $379, but it's available elsewhere for $300. But I also found the Shecom hard drive and the La Cie Lacie D2 hard drive on cnet. I'm not sure whether they require cd installation, though - it says you can just plug it in, but it doesn't specifically mention (like in the smartdisk description on the apple site) that cd installation is not required.
So do the Shecom and/or Lacie hard drives require software installation, or is there anything which has more than 80gb of space (the max space of the SmartDisk Firelite devices)?
