Unable to connect external hard disk
Hello!
My hard disk suddenly could not detect. When I look at the hard disk in the disk utility, it appears but the name is greyed out. I tried rebooting the computer, SMC and safe mode but the hard disk still could not be detected. I have no idea what is wrong. I tried changing cable to plug in and tried with a hub to plug the hard disk in and it's still doesn't work. The hard disk is running when it's plugged in.
Please help, thank you!
