Hello to all, I have a dual boot PC with Windows 10 and Debian 11 This PC has 2 drives, one SSD that has both operating systems and a HDD where I store all other files (documents, music, images, ...) The goal is to share this HDD between Windows and Debian. To do it, I added the following line to the fstab file: UUID=ACB23705B236D414 /mnt/windows ntfs-3g defaults,umask=000 0 0 the folders lount without any problem to /mnt/windows, all with the correct permission settings (rwx) : $ ls -l /mnt/windows/ total 80 drwxrwxrwx 1 root root 4096 14 nov. 20:20 '$RECYCLE.BIN' drwxrwxrwx 1 root root 4096 24 nov. 15:59 CloudStation drwxrwxrwx 1 root root 4096 21 nov. 11:44 Documents -rwxrwxrwx 1 root root 8192 25 juin 08:15 DumpStack.log.tmp drwxrwxrwx 1 root root 4096 22 nov. 20:41 Images drwxrwxrwx 1 root root 4096 24 nov. 11:53 Music drwxrwxrwx 1 root root 8192 23 nov. 06:21 'System Volume Information' drwxrwxrwx 1 root root 40960 21 nov. 22:22 Downloads drwxrwxrwx 1 root root 4096 21 nov. 19:44 Videos My problem is that in some sub folders, I'm not getting the write ("w") permission. For example on the "Documents" one: $ ls -l /mnt/windows/Documents/ total 117 drwxrwxrwx 1 root root 16384 24 nov. 15:59 User1 -rwxrwxrwx 1 root root 0 26 nov. 2020 Default.rdp -rwxrwxrwx 1 root root 432 11 mars 2021 desktop.ini dr-xr-xr-x 1 root root 40960 24 nov. 15:59 User2 drwxrwxrwx 1 root root 16384 24 nov. 16:00 Public drwxrwxrwx 1 root root 4096 24 nov. 15:59 User3 dr-xr-xr-x 1 root root 20480 21 nov. 12:05 Scan -rwxrwxrwx 1 root root 18432 4 déc. 2016 Thumbs.db drwxrwxrwx 1 root root 0 16 nov. 23:13 'Unified Remote' Most of the folders are OK, but I ave User2 and San that doesn't have the write ("w") permission... Do you have any idea on whats going on? Thanks in advance for all the help, Berst regards, Marc
