dumpef2s output attached when i booted into windows and then back to linux there was always additional checksum error in superblock. when i was booting only to linux then there were always errors i wrote in previous comments, but I don't remember exact numbers
all this started because of damaged disk (hw problems), I had to buy new one and transfer what I could. i was using ext2fsd for years, but on partitions created years ago. it seems it doesn't like ones created with ubuntu 16.10. I already reported this problem to ext2fsd project When I identified that issue was related with ext2fsd I removed it from windows, reformatted ext4 partitions and restored data from this damaged disk again - now everything seems to work without any problem. That also means I am not currently able to reproduce problem - I don't want to damage data, restoring takes very long time ** Attachment added: "dumpef2s.txt" https://bugs.launchpad.net/ubuntu/+source/e2fsprogs/+bug/1637779/+attachment/4770160/+files/dumpef2s.txt -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1637779 Title: ext4 filesystem fails randomly with checksum error To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/e2fsprogs/+bug/1637779/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
