Windows has stopped this device because it has reported problems (Code 43)

Explains why code 43 occurs, which means Windows has lost communication with the drive or the driver has crashed.Sometimes you may see this error message: Windows has stopped this device because it has reported problems (Code 43).

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:

Desktop:

If you are using a desktop computer, connect the drive directly to the back of your computer.

Note: Is best not connect the drive to the front ports of your computer, on a USB hub or a switch.

Try again

Notebook:

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.
- Test the drive with SeaTools for Windows.
- Run checkdisk on the drive.
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.
