How should I reformat my Seagate Wireless Drive to use a MacOS file system?

Note: When this article refers to a Wireless Device it is referring to a Seagate Wireless, Seagate Wireless Plus or a Seagate Satellite.

If you have used your Wireless Device with Time Machine then you can follow the instructions below to get it back to factory settings.

The Seagate Wireless Device can be formatted as Mac OS Extended (HFS+). However, there are some limitations:

  • Be sure to use an MBR Mac OS Extended partition and not a GPT partition (see the steps below).
  • Do not use an Apple Time Machine partition. Time Machine will usually attempt to format the drive as GPT and make it bootable, which will prevent the Wireless Device from working in Wi-Fi mode. Follow the steps below to properly format the drive for use with Mac OS.
New: Apple File System (APFS)

The new Apple File System (APFS) requires the drive to be a GPT style partition.  Since your Wireless Device will only work with an MBR style partition, formatting your drive APFS will prevent the wireless features from functioning.

Formatting the Seagate Wireless Device to HFS+ in Mac OS

  1. Copy any files that you want to keep to another location. Reformatting the drive erases all data.
    Be sure to eject and disconnect any other USB drives before proceeding.
  2. Click Go on the Apple menu bar. (If go is not on the menu bar, click on your desktop background once to make it appear)

  3. Choose Utilities.

  4. Double-click Disk Utility; this will open a new window.

  5. Select the Wireless Device.
  6. Choose the Partition button.

  7. Click the minus (-) button to erase the partition.
    This will erase ALL data on the selected drive.
  8. Enter a recognizable volume Name, for example, Seagate Wireless Device.
    This is the name that will appear on the Desktop when the drive is connected to your Mac.
  9. Click the Options button.
  10. Choose Master Boot Record (GUID and Apple Partition types will not work).

  11. Click OK.
    Formatting the drive will erase all data on the drive. Be sure to copy anything you want to keep before proceeding.
  12. Click Apply on the Partition screen to start formatting the drive.

    The drive should be ready to use after a few minutes. Be sure to check that the Partition Map Scheme is Master Boot Record. If it reports as GUID or Apple Partition, restart the processing from step 7.
If you have a newer Mac and your Disk Utility does not look like the examples above, please follow the updated formatting instructions found here.  Please remember to use the settings discussed in this article.
