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,

The Windows disk/ partition/ volume/ filesystem stack and the Linux stack are fundamentally different. When using one filesystem with both operating systems, features and interoperability are opposites. A simple filesystem, such as FAT, has minimum features and maximum interoperability. A complex file system, such as NTFS, has maximum features and minimum interoperability.
If you want to know the reasons behind the interoperability effects that you are seeing with NTFS under Linux, then I suggest that you study Windows drive/ partition/ volume/ filesystem technical documents, the corresponding Linux technical documents, and the Linux ntfs-3g driver.
If you want a disk/ partition/ volume/ filesystem that "just works" with both Windows and Linux, then I suggest that you backup your data, zero the HDD, use Windows to partition the HDD, use Windows to format the partition using the exFAT filesystem, and restore your data. This should give you a filesystem that all users and processes can access under both Windows and Linux. If you want to limit access to all or part of the disk, then one solution is to create multiple partitions and filesystems, and mount each as required.
