External harddrive setup

Hi, brand new at all this. I bought an external hard drive for film editing etc. Can anyone help me with how do I get it up and running. I think I did something wrong as it takes awhile and has problems burning. The set up is not clear so I guessed alot. Thanks

What is the type of the drive?
Connected to your PC through USB 1 or USB 2?
What is your OS (Windows 98, 2000, XP, XPPro)?
