Your external hard drive isn't showing up on your Mac
The drive either isn't plugged in properly, the cable is damaged, or it needs to be mounted. Disconnect it completely, wait 10 seconds, and reconnect it firmly. If you see it in Disk Utility but not Finder, it just needs to be mounted by clicking the Mount button.
External drives need three things to show up on your Mac: a good cable connection, power for some drives, and a format your Mac can read. Sometimes the cable gets loose or the drive disconnects without unmounting properly. If the drive appears in Disk Utility but not Finder, it just needs to be mounted. We'll check the connection, mount the drive, and fix any format issues.
- ✓Have your external drive plugged into power if it has its own power cable
- ✓Keep the drive plugged into your Mac throughout troubleshooting
- ✓Have Disk Utility ready to open from Applications → Utilities

Skip, I just want a technicianCommon mistakes to avoid
- Assuming the drive is broken when it's just disconnected. Always check if it shows up in Disk Utility first

- Trying to reformat a drive without first checking if it's just not mounted
Signs you need professional help
- The drive doesn't appear in Disk Utility even after trying different cables and ports, the drive appears in Disk Utility but shows an unusual status you don't recognize, or you get an error message saying the drive is unreadable or needs to be initialized.
