It did have some corruption through its 3 year life time. This was from one month ago: sudo btrfs device stats / [/dev/sda5].write_io_errs 0 [/dev/sda5].read_io_errs 0 [/dev/sda5].flush_io_errs 0 [/dev/sda5].corruption_errs 996 [/dev/sda5].generation_errs 0 On the latest scrub that I took note of the results though, it didn't have corruption: sudo btrfs scrub status / scrub status for f2e4e4d3-2d8e-4764-a818-de9176405c4b scrub started at Fri Apr 17 14:42:47 2015 and finished after 146 seconds total bytes scrubbed: 66.10GiB with 0 errors Best regards, Miguel Negrão
