Western Digital Desktop Extended Diagnostic stuck on 10%

I did a quick SMART scan which took a few minutes. Then started an extended one, however it’s been stuck on 10% for 12 hours now, is that normal?

Thanks, Dave

The extended test can be really slow on large capacity disks

It’s unusual for an extended SMART scan to be stuck at 10% for 12 hours. First, check if the software is still responsive; if not, try to cancel the scan and restart the program. If it remains unresponsive, reboot your computer and consider running a different scan, such as a quick scan. If the issue persists, it could indicate a problem with the drive itself, so check for any unusual noises or signs of malfunction
