DO NOT GET THIS DRIVE!!!!
The drive comes with a read-only CDFS partition that cannot be deleted, reformatted or altered in any way. This partition automatically mounts itself as a 'virtual CD'. So every time you plug it in, TWO devices show up instead of just ONE hard drive. This causes all kinds of problems with various devices, and may cause some programs to crash. You cannot alter or change the contents of the virtual drive, so you cannot use it to mount iso images etc… It simply offers the same Iomega crapware, every… single… time… you…. plug… it… in…
I have contacted Iomega, and they have confirmed that the partition cannot be removed, and that "they are sorry for any inconvenience." If you actually are planning on encrypting your files with the built in encryption software, this may be a good drive for you. But if you don’t plan on using it, get a different hard drive. So unless you can live with the virtual drive looming on your computer incessantly offering its crapware, I would recommend looking elsewhere.
