Unix systems (Mac, BSD, Linux, Unix, etc) in general does not support well removing a mounted volume without un-mounting it first, the main reason is that volumes cache is enabled by default.
To my knowledge, macOS does not have a way to change that default behaviour. (other Unix systems can be configured through the /etc/fstab and /etc/mtab files)
If you use the command line, you can unmount the volume and remount it without the cache (activating synchronous I/O) and thus be more resilient.

You know, convenient and easy to remember commands such as:

umount /dev/usb/0/first/left-side -i -nc -r -v -mr

Where:
-i means do it immediately
-nc means 'no cache' mode
-r means 'really, I mean it, please do it now'
-v means verbose output (include weather, biorythm and horoscope)
-mr means 'more resilient' mode

I love *nix - endless opportunities to poke fun. Unlike Windows where there really is only one - "you should be using *nix"
