“External Drive Not Showing Up in Finder”
What This Means (In Plain English)
You plugged in an external hard drive or USB drive but it is not appearing on your Mac. The drive might not be compatible or may need to be mounted.
Common Causes
- •The drive is not properly connected
- •The drive needs to be manually mounted
- •The drive format is not compatible with macOS
- •A faulty cable or USB port
How to Fix It — Step by Step
- 1
Check that the drive is properly connected — try unplugging and plugging it back in.
- 2
Try a different USB port on your Mac.
- 3
Try a different USB cable.
- 4
Open Finder > Settings > Sidebar and make sure "External Disks" is checked.
- 5
Open Disk Utility (search with Spotlight) — the drive may appear there even if not in Finder. Select it and click "Mount".
- 6
If the drive was formatted for Windows (NTFS), your Mac can read it but not write to it. You may need special software to write to it.
How to Prevent This in the Future
Always "eject" drives properly before unplugging them. Use drives formatted as exFAT for compatibility between Mac and Windows.
