Every now and then (it seems to me especially after TM backups, but that is about the only reason I plug them in), I am unable to eject and external hard drive by clicking the eject button in Finder (it simply does nothing). It works when initially plugging it in, but not after the backup.
I can however eject it by right-clicking and choosing
Eject, no problems.
This happens with two different drives I use for backup.
Has anyone else experienced this issue or can suggest what the problem might be?
My OS is 10.10.3
