    I want to buy an external hard drive 2.0 USB but don't know whether to buy 60GB or 80GB. My HP PC says I have "512MB Ram memory" but also says I have "120GB DMA hard drive." How do I determine how much actual MB (or GB) I am using? Thanks

    What operating system are you running?

    How much hard drive space remaining doesn't really apply when purchasing an external drive. You have to determine what your external space needs are including what you plan to use the drive for.

    Thanks, Helix. How do I go about calculating the GB I need? I just use my PC for visiting web sites (occasionally watching a little video at newspapers and TV networks), creating and saving documents and spreadsheets, and e-mail. I have Windows XP Home.

    Also, I am confused about the 120GB "ultra hard drive"--how does that square with the 448MB RAM (I understand 1GB=10,030MB, which wouid equate to 44.7GB).

    Thanks again.

    Why do you think you need an external hard drive if you don't store much data on your computer? External hard drives are good for full system backups, but then you should have one close to your drive's capacity so it can handle such a task.

    You're confusing RAM and hard drive storage. RAM is memory. It's what's used when you open programs. Hard drive space is where your files are stored (e-mail spreadsheets, music, pictures, etc.).

    To see how much hard drive space is remaining, right-click on My Computer and click Manage. Then click on Disk Management.

    If you are talking about the GB and MB listed in the typical sales specifications for a hard drive, 1 GB = 1,000,000,000 Bytes or 1,000 MB.

    If you are talking about GB and MB disk capacities and file sizes as reported by Windows, 1 GB = 1,073,741,824 Bytes or 1,024 MB.

    Not sure where you got your "1GB=10,030MB" numbers. :confused: :confused:
