- Make sure that you're using a backup disk supported by Time Machine.
- Unless you're using a network backup disk, make sure that your backup disk is connected directly to your Mac, not through a USB hub or other device.
- If your backup disk is connected directly to your Mac, use Disk Utility to repair the disk.
- If you're using a network backup disk, make sure that the network connection is good and your Mac is connected to the same network as the backup disk. If you completed a previous backup successfully, verify that backup: Press and hold the Option key while choosing Verify Backups from the Time Machine menu in the menu bar.
- Make sure that the firmware of your backup disk is up to date. Check with the manufacturer of the backup disk for details.
- If no other solutions work, start over: Erase your backup disk, then use Time Machine to select it as your backup disk again.
