Can this be used on multiple devices (laptop and a desktop)?
Both computers run Windows 8. Can drive be segmented for the data for the separate machines? No need for security between the two, just organization
I do not know if the drive can be partitioned, but I would suspect so. I'm guessing that is what you mean. In that regard, I apologize if this answer is too obvious, but you could establish separate directories on the external harddrive, one for each computer, and via the drag-n-drop method back up the separate computers in their separate directories.
