How to format your drive for use with both Windows and Mac (FAT 32)


Due to the differences between a Mac OS X and Microsoft Windows, formatting a drive for both Mac and Windows will limit maximum file sizes of 4GB. If you plan on using files larger than 4GB, please format the drive for ONLY Mac (HFS+) or ONLY Windows (NTFS).


NOTE: The steps below use the G-Drive slim as an example only. The steps remain the same regardless of the G-Technology product you're attempting to format.


WARNING: Any data on the drive will be erased in this process. 
 Please backup any data on the drive before proceeding.


Follow these steps to format your drive for both Mac and Windows:

  1. On your Mac, connect and power the drive
  2. Open Mac HD, Macintosh HD or the name of your main hard drive in the finder
  3. Open Applications > Utilities > Disk Utility

  4. Once the Disk Utility application has opened, your external hard drive should be listed on the left. It should show the drive size with a second indented line beneath it that shows the existing partition

  5. Select the Erase tab at the top of the screen

  6. Select MS DOS (FAT) for the volume format option
  7. Change the name of the drive if desired
  8. Click Erase at the bottom of the screen. You will receive a warning message asking you to confirm the erase procedure

When the process completes, the drive will be ready for use by selecting it on your Desktop or Finder window
