I'll offer a guess. Modern disk drives have a full up controller on board. That controller has enough smarts that when it detects an error it can correct, it will transparently correct the error and re-write the sector. Sometimes it takes more than one such read and re-write to make the correction permanent. In GSmartControl, under the Statistics tab, keep an eye on the number of reallocated sectors. If you see a non-zero value, your drive is in trouble. At the prices of modern hard drives, it makes sense to replace early rather than endure the hassle of restoring from backups, no matter how well done they are. Also,if you haven't already done so, set up smartd, which is part of the smartmontools package. And think about having a spare drive on hand for the day when that drive goes south. -- Does anybody read signatures any more? https://charlescurley.com https://charlescurley.com/blog/
