Every time I mount an encrypted external hard disk drive,
I receive below error message when I try to unmount?:
One or more files on this device are opened in application "kioslave5".
Only think I can do is reboot.
Running up-to-date Manjaro KDE on the “Testing” branch.
You must first close all file manager windows and terminal sessions open on a folder on the filesystem before attempting to unmount it, as well as all applications that have loaded files from said filesystem.
All I did was transfer (copy) files from OS drive to external HDD.
Nothing is still using the external HDD after the copy is finished.
That may be what you think, but the I/O is probably still continuing in the background. The drive is probably buffering the transfer, and with encryption it’ll take even longer.
