# How do I stop "Disk Not Ejected Properly" warnings every time my Mac sleeps?

When the warning appears after every sleep, the connection is being cut while the Mac sleeps — usually by a hub, dock or adapter that powers down its ports, or by a bus-powered drive that can't wake reliably. Connecting the drive straight to a port on the Mac fixes it in most cases.

Try, in order:

1. Plug the drive directly into the Mac instead of through a hub or dock.
2. Use the cable that came with the drive, or another known-good one.
3. If you must use a dock, use one with its own power supply.
4. On a desktop Mac, check **System Settings → Energy** (or Energy Saver) for an option to put hard disks to sleep, and turn it off if your drive struggles to wake.

If the drive still drops out, test it with **First Aid** and on another port — an intermittent drive is worth replacing before it fails. Storage Studio pauses its moves while the drive is away and carries on when it returns.
