TYPO3 Core

Hi,
i would like to use some custom File Storage. The one already exists is 'fileadmin/' that is created by default. I tried to create new storage in 2 locations: my general record storage folder and the root page (uid 0). In both locations i can create new storage record and fill all data i want. Then when i go to List module my storage is listed at the very bottom but is marked as offline (folder with the padlock icon).

I moved back to edit this record, set "Is online?" checkbox and saved changes (the first save icon that returns to record) and after record form reload this options was checked. Then i closed form and clicked edit record again and now the "Is online?" checkbox was not marked. So whatever i do i can't make my storage online :/
