I was wondering if anyone could possibly help, Im tearing my hair out! I recently upgraded to El Captain (wish I never had after all the problems I have encountered!) when I plug my western digital hard drives in I can see they connect in the system report but they don’t seem to mount on the desktop?!
Once I upgraded they mounted for a little while, I then left my computer and on return they had disconnected and now won’t mount.
I have tried a fresh install of El Captain to no avail, I have read many forms but can’t find the answer.
