# Why does my external hard drive click or beep?

Repeated clicking or beeping usually means the drive can't spin up or read properly. Sometimes that's simply too little power; often it's a mechanical fault. SSDs have no moving parts, so they don't click.

What to do:

1. Try a different port and cable, and connect directly to the Mac rather than through a hub.
2. If the drive has a power adapter, use it; some portable hard disks need more power than a port or hub gives.
3. If it mounts, copy your most important files off first.
4. If it keeps clicking, stop powering it on and consider a professional recovery service for files you can't replace.

A clicking drive shouldn't be trusted with new data. If it holds things Storage Studio moved, see [what to do when your fast drive is failing](https://storagestudio.us/faq/external-drives/my-fast-drive-is-failing-what-should-i-do).
