Windows Defender stopping me from ejecting harddrive

I don't disagree with anything posted here. I am still having some issues with my USB drive having corrupted files and or folders after coping new data to the drive. It could be because Defender is still running and maybe not clearing the new files as safe. I do not know. I've continued to look for ways to get around this issue. Maybe Defender is the problem. And where is msft in all of this??

I am having the same issue and have tried several things, but only restart helps.

I use Windows 10 Pro - Version 1909 - OS build: 18363.959 and this Windows Defender problem also occurs on my PC.

Jose, 

The quick removal for external drives is already set as default. That is not the issue, when eject is issued they should first stop the activity of windows defender on the drive and then eject correctly.

If you see the problem also with 1909, that means that they introduced the bug with some recent changes of the defender also in 1909.

I had 1909 for over a year and never had any problems with eject.

It all started for me with v 2004 in 5 different machines.

Also I don't get the problem with any insider development build up to build 20180.

@ fg2001,

Thanks for the answer!

1. • Yes, Quick Removal by default is already OK. I posted the link just to show Microsoft's official information about this feature.

2) - "... If you see the problem also with 1909, that means that they introduced the bug with some recent changes of the defender also in 1909 ..."

Yes, the USB device removal problem and Windows Defender in version 1909 started recently. Before it worked correctly.

Hi Jose, 

Thanks for the confirmation. I just hope that MS comes out with a fix soon.

As I said earlier the problem is not just with USB devices, but also with external SATA devices.
