Answer 1

A "USB external disk CASE" is a case which will hold an separate INTERNAL type hard drive (which you will have to purchase also) and will plug into your USB ports on your computer. Save your rs750 and put it toward a large INTERNAL hard drive and then install that into your Compaq. There is a web site to guide you through the process of installing hard drives and upgrading the memory on your computers. Just be certain that you purchase the proper memory for your computers by going to:

very long and complicated to describe. surely, in case you may get your computing device besides up out of your USBcontinual (i.e. E:) whilst initiating, then you definately can. yet i've got individually under no circumstances ever seen somebody do it, and that i understand alot of persons prefer to get it completed.
