Hard disks need lots of free room to shuffle data around quickly

Your computer uses a hard disk to store all it’s data on which most people know.  What a lot of people don’t realize is that a hard disk is also used to temporarily store information on by programs while they sort tasks out.

Imagine a hard disk is like a room and the data you store on it are objects in the room.  Now to move these object around you need a bit of spare space right?  It’s pretty hard to move a big wardrobe when you have no floor space!  Disk drives are the same although it’s all 1′s and 0′s and things are far more complex (they always are with technology it seems!).

You need to keep 15% of your hard drive free or it’ll take a lot of time trying to find spare space to place your files and do big calculations and processes.

To see how much space you have left on your computer’s hard disk click on the start menu and then select “computer” or “my computer”:

If it’s unclear how much hard drive space is left make sure you look at the “C:” drive or whichever drive is biggest on your computer.

You can get an in depth report of your hard drive by right clicking on it and then selecting “properties”:

You can see a pie chart of the free/used volume on the hard drive's properties window

So have you blocked up your computer?  If so you need to delete unused programs, movies or music off your computer to free up some spare space.

You may have some computer games or large programs taking up a lot of space on your laptop, these can be removed in the “add/remove programs” tab in the control panel.  Check out the McAfee removal process to see how to remove programs from your personal computer.

An added bonus of freeing up 15% of data is that you may hear a lot less “grinding” noise from the computer as it swap around data frantically!
