How to Format Hard Drives

If you can’t copy a file to your hard drive it likely isn’t formatted for the operating system you are using. This is common with new drives which frequently come formatted for Windows computers in the NTFS format, which is not comparable with Mac OS. To copy files to the drive you must re-format it using a different type of formatting. This process only takes a few minutes but will erase all files on the drive so make sure you copy off any files you need before reformatting.

Choose your format

  • ExFAT – Compatible with Windows and Mac Operating Systems. Good option if you use both platforms.
  • Mac OS Extended (Journaled) – Standard MAC only format
  • NTFS – Standard Windows only format
