Hi
I have a strange problem and I could not find the fix.I loose permissions to write on external hard drive after a while.when I start the session everything starts normal.But after a while I can not save anything on it or modify anything .And I cannot repair when it gets into this stage and whatever I do I get error code -50 .After a force eject and mounting again everything becomes as it should .
could anybody help me with this situation
mac os Sierra
peace
Error -50 is a very unhelpful generic communications error with a number of possible causes. Something between the drive to which you are downloading and the drive from which it is all coming is not working correctly, with probably dozens of possibilities.
