Ask Max: Fixing File Permissions as Root User
I screwed up. I often use "get info" on a folder and change the ownership to "no access" This works great so the kids don't accidentally play with my work. But I did the same thing, changing the ownership privileges to "no access" on 1 of my partitions shows on my external drive. Now the other partition shows up, as normal but the "no access" one will not mount. I can see it fine in disk utilities but still can't mount it.
How can I mount the partition so I can revert the privileges back?
Hope that brings your partitions back.
