Permissions for external HDD

I'm a bit new to openwrt, so I'd like to ask for help.
Device: Banana Pi R2 Pro.

Sata HDD attached, and mounted. EXT4.

config mount
	option target '/media/disk1'
	option uuid 'c5c8b735-56ec-4912-8ee6-69fbf59201c8'
	option enabled '1'
	option options 'rw,async'
	option enabled_fsck '1'
	option fstype 'ext4'

I've created several folders on /media/disk1

ls -l /media/disk1/
drwx------    2 root     root         16384 Aug 23 00:59 lost+found
drwxrwxrwx    2 root     torr          4096 Aug 23 12:15 movies
drwsrwsrwx    2 root     torr          4096 Aug 23 12:15 music
drwsrwsrwx    2 root     torr          4096 Aug 23 12:15 tmp

I've created several accounts: qbittorrent, tranmission, added them to group torr


But such users can't do anything with this HDD

$ sudo -u qbittorrent touch /media/disk1/movies/1
touch: /media/disk1/movies/1: Permission denied

Started as daemons this users also can't write to HDD. Please assist how this could be fixed.

what are the permissions for /media/disk1 ?

surprisingly fixed with

root@OpenWrt:~# cd /media/disk1/
root@OpenWrt:/media/disk1# chmod -R -v 777 *

However I'm not sure if this correct solution. And why specific permissions on folder isn't sufficient.
