I would use a usb drive (WD 3TB) for my data directory [folder data]. How to mount this disk with the www-data group? I can not find a clear documentation to use my usb disk by default. ---

What file system? If it’s only used for Nextcloud, I would personally choose a Linux file system. It’s better supported and more stable. If you use NTFS: > [@You don't have permissions to upload or create files here - local (external ntfs-3g storage)](https://help.nextcloud.com/t/you-dont-have-permissions-to-upload-or-create-files-here-local-external-ntfs-3g-storage/5420/4): > > Managed to solve the problem past the recommendations made by tflidd and I am typing the solution here to probably serve others who may run into this problem. fstab #Windows-Partition UUID=537FEF451930795B /media/win ntfs rw,auto,users,exec,nls=utf8,umask=003,gid=33,uid=33 0 0 Reboot sudo reboot Force NextCloud to rescan files cd /var/www/nextcloud sudo -u www-data php console.php files:scan --all And your ntfs local external storage is back in business. ---

I look code (thanks, is open source) file Setup.php ``` // validate the data directory if ( (!is_dir($dataDir) and !mkdir($dataDir)) or is_writable($dataDir) ) { $error[] = $l->t("Can't create or write into the data directory %s", array($dataDir)); } if(count($error) != 0) { return $error; } ``` I test with my php code and obtain ((!is\_dir [= FALSE]) AND (!mkdir [= TRUE])) OR (!is\_writable [= TRUE]) ==\> Can’t create or write into the data directory: /media/rg ((!is\_dir [= TRUE]) AND (!mkdir [= TRUE])) OR (!is\_writable [= TRUE]) ==\> Can’t create or write into the data directory: /media/rg/myNextcloudData Evidently my data directory is not writable. ``` ls -l drwxr-x---+ root root /media/rg drwxrwxr-x www-data www-data /media/rg/myNextcloudData ``` Problem is probably witih “rg” (rg is the user) ---
