First, we know from a number of studies, including the famous (and now kinda old) Google study that a huge percent of drive failures come with no SMART errors. Second, SMART is only saying its internal test is good. The errors are related to data transfer, so that implicates the enclosure (bridge chipset or electronics), the cable, or the controller interface. Actually it could also be a flaky controller or RAM on the drive itself too which I don't think get checked with SMART tests. -- Chris Murphy -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
