Mounted drive - permissions

Jagera

I've just mounted a spare partition to a folder, and its set the permissions to root.

I changed to root in a termila (using su) and did the following:
mount /dev/sda3 /home/bw/MediaFiles

I've tried a number of commands using chmod, but after 6 or 8 various attempts, I am just a tad worried I may cause permission issues, having set/unset/ thigns with so many variations.

So, how do I allow full access to the bw user to this newly mounted drive/folder?

Check drive is actually mounted: '$ sudo mount'. Can you post output of '$ ls -l ~/bw'. The probable solution is :

$ sudo chown -R bw ~/bw
$ find ~/bw -type d -exec chmod -R u+rxw {}\; 
$ find ~/bw -type f -exec chmod -R u+rw {}\;

Good luck.

EDIT - the initial sudo chown command seems to have worked. Despite the error I got in the second command, I now have access to this drive.

Juts wanted to confirm your command:
my login is bw, mounted folder is ~/bw/MediaFiles

I ran the first command as:

sudo chown -R bw ~/MediaFiles

which ran without any return message.

The next command failed, I ran as:

find ~/MediaFiles -type d -exec chmod -R u+rxw {}\;

and received the following: find: missing argument to `-exec

have I mistyped or misread something?

Tillotson

My mistake, missed a space between curly brackets and backslash.

Commands should be:

$ find ~/MediaFiles -type d -exec chmod -R u+rxw {} \; 
$ find ~/MediaFiles -type f -exec chmod -R u+rw {} \;

I am losing the mount after reboot, so the MediaFiles folder is on the other partition, where my /home folder is located.

Tillotson

To make the drive mount on boot you'll have to edit "/etc/fstab"
