This usually means that the driver (which does NOT come from Seagate; this driver comes from Windows) has lost communication with the drive or the driver has crashed.
To resolve this problem, please follow this procedure:
- If you are using a desktop computer, connect the drive directly to the back of your computer.
- Try again
- For notebook computers, simply try all the different USB ports available.
- Replace the USB cable and try again.
Other available steps:
- Run diagnostics on the drive. If the drive fails the diagnostics, replace it.
- Update your computer's USB drivers. See Document ID: 218931 for instructions.
If the drive functions properly when directly connected to the computer but not when connected via a USB hub, and if you need to use a hub, try a powered USB hub, which may allow the drive to operate better.
You may also try connecting only the drive to the USB hub, then reconnecting your other devices one at a time to narrow down where the problem lies.
