Seagate hard drive not showing in finder and also in disk utility
PLEASE HELP.
When I'm connecting my seagate hard drive to my macbook air, it lights up. Meaning my HD is working. But it is not showing either in finder or in disk utility. I don't know what to do. I have very important files inside my hard drive. Please help me.
I have another seagate hard drive and when I tried inserting it to my macbook air, the HD was read by my mac. So I really think the problem is my other hard drive. What to do next?
MacBook Air, iOS 11.4.1, null
