I have a G-DRIVE Mobile SSD (1TB) attached to my Apple MacBook Pro (OS 10.15.7) with the supplied USB-C cable. If I have to restart my computer for some reason, the drive does not remount - i.e., it does not show up on the desktop. I have to detach the drive and re-attach it for the drive to show up on my desktop.

Hi,

Please be informed that we usually recommend safely ejecting the drive from the computer when there are no activities performed on the drive and plugin back the drive back to the computer when need to work on the drive. However, you may contact apple in order to fix this issue, as it’s related to mac mounting after reboot and there are some settings that can be changed in mac to make it work with the drive.

When you connect an external hard drive on Mac, it will show up on Desktop, Finder, and Disk Utility. But sometimes the external drive won’t appear at any of these places. To fix the issue, you can try the below methods:

  1. Change MacOS settings
  2. Reset Mac firmware settings
  3. Fix external hard drive connectivity issue
  4. Troubleshoot external hard drive
  5. Recover data from non-mounting external mac hard drive using reliable data recovery software

Further, I suggest you to check the below link for detailed steps to be followed in each method above.

Hope it helps!

My problem is not that the external drive will not show up when I connect it to my Mac. The problem is that if I start with the drive connected, mounted, and showing up on the desktop and then I do a restart, the external drive is not mounted. I have to disconnect and reconnect the drive.

If your external hard drive keeps unmounting itself, then there can be various issues for the same.

Below are the few fixes, you can try to resolve the issue:

  1. Connect to a different USB port
  2. Turn off USB selective suspend
  3. Disable your PC to turn off Mass Storage Device
  4. Disable USB legacy support in BIOS
  5. Check disk partition errors and repair

Hope it will help.

The drive doesn’t unmount itself. It’s just that restarting my Mac causes the drive to become unmounted.

  1. The external drive is connected to my Mac with a Thunderbolt (not USB) cable that was supplied with the drive when I bought it.
  2. My Mac does not have anything called “USB selective suspend”.
  3. I don’t know what this is. I have a Mac, not a PC.
  4. My Mac does not have anything called “USB legacy support in BIOS”.
  5. This has been done multiple times.
