I should say that whenever upgrading firmware on a drive please make sure you have recent backups of your data, especially considering the nature of this issue.
It's very possible that the electron leakage in the NAND may have already corrupted your data, and the new firmware may not be able to restore the infrequently used/rewritten sectors *(not confirmed, but given my understanding of the problem this is a plausible explanation for some of the issues others are seeing). That being said the new firmware is supposed to help avoid this situation in the future, and as suck I whole-heartedly recommend the upgrade. Not only does it fix this issue, but performance is again restored. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1338706 Title: Samsung SSD 840 failed to get NCQ Send/Recv Log Emask 0x1 failed to set xfermode (err_mask=0x40) on upstream kernels >= 3.12 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1338706/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
