2. Mounted external drive won’t eject in Windows 10
Now, this is rather peculiar. Problems with mounting a certain drive are one thing, and the reasons spectrum is broader.
On the other hand, the issues one can experience with the inability to eject certain external hard drives are mostly provoked by the background processes.
Namely, some background process associated with the mounted drive prevents it from ejecting. Of course, you can unplug it/shut it down without the Safely remove feature.
That can, consequently, lead to more complex errors and further issues. What you’ll need to do is to follow the solutions we enlisted below and look for improvements.
Hopefully, you should be able to eject the mounted drive safely, without any risks of data corruption.

However, some user reports outlined the boot issues concerning the external drive. They were unable to boot to Windows 10 from the external drive, even though this worked great on the previous Windows iterations.
When you look at it, it’s quite obvious that the BIOS (UEFI) is the one to blame. However, it doesn’t mean that the BIOS is the only culprit. We enlisted all known troubleshooting steps below:
