External Hard Drive
A typical external hard drive


An external hard drive is a portable device used to store data. They are just like the hard drives already in a computer except, as the name implies, they are external. They can be disconnected and reconnected at will. Typical external hard drive sizes range from 500GB to 3TB with more expensive ones ranging from 3TB to 4TB. External hard drives are useful for backing up data and for the use of keeping data in two locations in case of unforeseen computer crashes. External hard drives are also useful when you need to backup your data before exchanging your laptop or before the laptop buyout during graduation week.

  • You will then need to select the name of your external hard drive from the left hand column. It is critical you do not select the hard drive for your laptop which will be the first option from the column.
  • Once you have the external hard drive selected, as highlighted (blue) in the image, select the "Erase" tab (red arrow) right after the "First Aid" tab.
  • Select the "ExFAT" option within the "Format" list (orange arrow).
  • You can rename the external hard drive to whatever you like within the "Name" text box, beneath the "Format" box.
  • At this point, you should double check that you have the external hard drive highlighted and not the hard drive for your laptop.
  • If you are positive that the external hard drive is highlighted and selected, you can select the "Erase..." option in the bottom right corner of the window to format your external hard drive (green arrow).

If done correctly, you will see your hard drive appear on your desktop again and it will be renamed to whatever you entered in the "Name" text box. You can now drag and drop your data onto your renamed external hard drive.
