i want an ultraportable laptop, but i cant find any that have an optical drive. if i buy a portable hard drive can i put dvds on it and play them on my hp mini notebook?

Answer:
Yes. You can put movies on your laptop's hard drive so why would a portable hard drive be any different? A portable hard drive would be useless if it couldn't hold the same files as the hard drive on your computer. Portable hard drives have a USB that plugs right into your computer so you'll be able to play then on your hp mini notebook. Or you could just purchase a 16 GB or more flash drive. That would be more portable than a portable hard drive. It may even end up being cheaper. But it all depends on how many movies you plan to store at one given moment.
Answer:
Yes, you totally can. I’ve an external 500 GB hard drive that holds nothing but movies, shows, and certain applications. You just plug it in via USB to any personal and you can play your movies, shows, etc.
Answer:
yes it could hold any data that a computer can.
