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's not formatted in a way your Mac understands. First, disconnect it completely, wait 10 seconds, and reconnect it firmly. If you see it in Disk Utility but not Finder, it can need to be mounted — try right-clicking it in Disk Utility and selecting Mount.
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.

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
- Not checking the power cable — many external drives have their own power supply and won't work without it
- Trying to format a drive without first checking if it's just not mounted
Signs you need professional help
- The drive doesn't appear in Disk Utility at all even after trying different cables and ports
- The drive appears in Disk Utility but shows a RAID status or other unusual state you don't recognize
