"Yes, I use a SSD cache memory" Windows and Linux do not use compatible cacheing. On a dual-boot computer, you have to disable the cacheing altogether. See for instance http://useranswer.com/answer/dual-boot-installation-of-ubuntu-12-04-lts-on-hp-ultrabook-envy-4-1002tx/ However this is a risky operation, do a full backup before trying.
"What should I do to be optimal?" You should format your partitions for 4K sectors. As your primary and logical partitions start on a sector boundary, you need not repartition. On sda6 you have no data, so reformating is easy : sudo mkntfs -f -L mis-doc -s4096 -c4096 /dev/sda6 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1202021 Title: [Solved] Not write folders and files in partition NTFS (problem after restart) / Problem with memory cache SSD To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ntfs-3g/+bug/1202021/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
