Observed similar symptoms on Ubuntu 24.04 on a NTFS partition on a USB SSD. (wrong fs type, bad option, bad superblock on /dev/XXXXXXXX, missing codepageor helper program, or other error).
The partition is not a Windows system partition. It "merely" has data. The partition mounted without issue with Ubuntu 22.04 on the same laptop; and still mounts without issue on another Ubuntu 22.04 laptop. After sudo ntfsfix -d /dev/sdb5, with 24.04, the partition appear as mounted in Disks. And files can be accessed in Files/Nautilus. Still OK after I "safely removed drive" and reconnected. Not tested after a reboot. Good luck. sudo apt-cache policy ntfs-3g [sudo] password for XXXXXXXX: ntfs-3g: Installed: 1:2022.10.3-1.2ubuntu3 Candidate: 1:2022.10.3-1.2ubuntu3 Version table: *** 1:2022.10.3-1.2ubuntu3 500 500 http://be.archive.ubuntu.com/ubuntu noble/main amd64 Packages 100 /var/lib/dpkg/status -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2062972 Title: ntfs partition does not mount with linux 6.8 and CONFIG_BLK_DEV_WRITE_MOUNTED=n To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2062972/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
