What this does is change the ownership of the /data folder to jordan and sets the permissions so all users have read/write access to the folder's contents but nobody has execute permissions. Since this is a data folder you probably don't want anything in that folder to be able to run, or execute. Open a terminal and type:
sudo chown -R jordan /home/jordan/data; sudo chmod -R 666 /home/jordan/data
That should give you access to your data folder.
Insanity: Doing the same thing over and over and each time expecting a different result.
Democracy is 2 wolves and a lamb voting on the menu. Liberty is an armed lamb protesting the electoral outcome. A Republic negates the need for an armed protest.
