Hi folks
I'm sure there's a way to find out what's using this device - I'm no Windows expert so it might be easy - in linux it's a doddle with pid etc etc but in Windows - I've no idea. The device was originally used to run Macrium to image my W11 system which completed properly and closed, but the device still remains "busy". W11 running on a Real system - not a VM just to add info.

Any Ideas please

Surely in 2021 though any sensible OS should be able to diagnose what the problem is and display a sensible message such as process xxxx or application yyyy is holding a lock, enqueue, or using this device . The OS has obviously detected that the device can't be released so c'mon OS writers -- these days it can't be that difficult to add sensible stuff into the kernel, dispatcher or task manager. It's not 1970's where every byte counted. !!!

Try Sysinternals from Microsoft, it's tools are much more powerful that those in the OS Process Explorer is probably the best place to start - and you will be pleased to know there are CLI versions of a lot of the tools ;)

@jimbo45 It is much wiser to start with what you already have, ie start with Task Manager and Services.
Also try find up what runs in background. For this You can use additionally to before named managers the Resource Monitor.

I wonder if admin cmd script (diskpart) will work on this.

Process Explorer, Find menu, Find Handle or DLL, but the culprit will likely be explorer.exe. The Recycle Bin can cause this problem. Right-click on Recycle Bin, select the disk in question and then click on Don't move files to the Recycle Bin and OK. It can help to exclude the drive in Windows Defender too.
