Founf your 2010 post.....saved my bacon

You could try to set the owner for that partition for yourself. When you right-click its empty background with pcmanfm as root and choose properties, set the owner for yourself and the group for users.


Well, the latest antix had all my drives, way wide open in permissions.
Tried everything under the hood, Command line:
chmod 770 /media/sda1
Right clicking on the specific drive and tightening the permissions... in both Rox, and pcmanfm

It would tighten them up ok, but magically flip back way wide open.
Went up a directory in /media,
did the above fix

Viola
all drives tightened down
