could not show the portable hard disk?
when I update to macOS Catalina, my macbook could not use portable hard disk any longer. When I connect the hard disk to the macbook, the flash-light of hard disk is on which shows that it is reading the data, but my macbook did not show the location of the disk. I could use my portable hard disk with my macbook before, could anyone help me to solve the problem?
MacBook, macOS 10.15
