Unable to write on External USB EXT3 HDD

Dear friends, I’m Luca from Italy.
I have a problem with my External EXT3 USB hard disk.
I try to explain..
I have an external box USB 3.0 with an HDD in EXT3 Format. I need it because I would like to connect at USB port of my RB3011 and move it the database of my hotspot.
To do so, I had format the HDD with EXT3 without errors.
When I connect it on RB3011, everithing is ok but I’m unable to write inside, like if I have not permission to write.
How can I do to permit the RB3011 write the database inside the External HDD?

Best regards
Luca

Hi, someone can help me?

Did you format it inside RouterOS or somewhere else? Try to format it in RouterOS in the “/disk” menu

I had similar problem with a SD card in a hEX-S. Could not copy files from and write to.

Formatting in ROS made no difference, Windows could not format the card. I put in a camera and formating was succesful and the card working again in the hEX-S.
