I have a G-DRIVE Mobile SSD (1TB) external disk attached to my Apple MacBook Pro (OS 11.6.8) with the supplied USB-C cable. If the G-DRIVE external disk is mounted on the MacBook and then I restart the computer, the drive does not remount. What I mean is that the G-DRIVE external disk does not show up on the desktop after the restart. I have to detach the G-DRIVE and plug it in again for the G-DRIVE to show up on my desktop. One more piece of information: I have two identical G-DRIVE Mobile SSD (1TB) external disks purchased at the same time, and one remounts after a computer restart, and the other one doesn’t.
Please be informed that we usually recommend to safely eject the drive from the computer when there are no activities performed on the drive and plug in 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.
If further assistance is needed, please open a case with our support team at the following:
