This wikiHow teaches you how to change an external (USB) hard drive's format on Windows and Mac computers. Formatting a hard drive can change the file system to make it compatible with your computer's operating system, as well as fix any non-physical errors on the drive itself. Be aware that formatting a hard drive erases the drive's contents in the process.

1. 1

   Plug your hard drive into your computer. Insert the drive's USB cable into one of the thin, rectangular slots in your computer's casing.

   • If you're using a desktop computer, USB ports are typically in either the front or the back of the computer's CPU box.

2. 2

   Open Start . Click the Windows logo in the bottom-left corner of the screen, or press ⊞ Win on your keyboard.
