Backing up to external hard drive suddenly crashes without completing

[ZXMB]

I've been backing up files to my external hard drive but part way through the process it stops and all of the so far through and the dialogue box and the File Explorer windows suddenly close.

I'm on Windows 8.1 with a Seagate hard drive.

Any ideas?

How are they being backed up? Did they ever completely back up? Are you doing anything else when this happens?

Issues like this need other details.

Hey there, ZXMB!

I'd advise you to reinstall the backup software and even try resolving the issue by uninstalling and reinstalling the external HDD as a device from Device Manager. I'd also see how the HDD will behave if you swap the USB cable that is connecting it and also the USB port on your computer.

You might also want to run the Short and Long tests from your HDD manufacturer's brand-specific diagnostic tool. This utility will help you determine the health and SMART data of the external drive.

Hope it helps. Keep us posted.
