My computer won't show my drive, though it detects it

I just barrowed my dads external drive, he uses it with MAc and its fully detectable on mac. I plugged it into my PC and everything worked normal as expected, but when i plugged it into my newer PC, it installed the device, but it never popped up the window to explore the drive. THe icon is also not present in the my computer area along with all the other drives. In the device manager and control panel it shows up, but all i can do is look at its properties and uninstall reinstal the driver. Why cant i view the drive and use it?

Check under admin tools/computer manager/disk management,  see if it’s there, but maybe doesnt’ have a drive letter assigned.
