How to format a hard drive for Mac OS X

This video post was inspired by two conversations I had with (on the subject of Time Machine backups) and (with two video files that wouldn’t copy onto a drive), so be sure to thank them if this helped you!

Here’s the video:

Here are the steps:

  1. Connect the drive to your Mac and power it up.
  2. If there is data on the drive, copy it to another drive. This will erase the data on the drive.
  3. Launch Disk Utility, either by using Spotlight, or by using Finder’s Go menu, selecting Utilities, then double-clicking Disk Utility.
  4. Click on the drive you wish to reformat.
  5. Double-check that the drive is indeed not a Mac OS formatted drive.
  6. Click the Erase tab up at the top
  7. Select either Mac OS Extended (Journaled) or Mac OS Extended (Case-sensitive, Journaled) if you will want to use case-sensitive file names. (Eg: AwesomeVideo.mp4  and awesomevideo.mp4 would be considered the same under Mac OS Extended (Journaled).
  8. Give the drive a new name.
  9. Click Erase, then a warning will appear to remind you of possible dataloss. Click Erase.
  10. The drive will be re-formatted and should be available quite quickly (usually less than twenty seconds)

That’s it! If you have any other things you’d like demoed, let me know!
