... be as good an indication of trouble as smart. i/o errors have the benefit of not being drive dependent. the recovery will need to be done by hand anway, as fs doesn't have the concept of device state. (there are some subtile difficulties, too. sometimes drives read an lba correctly but writes fail.) for something more automatic, devices would need state and an online ...
...do you check if your disks are still ok? I know I could invest The newer high capacity drives all have high "raw error read rates" but they're generally all corrected as indicated by an equivalent...you see that incrementing, it's time to decommission that disk for anything other than scratch storage. Such drives are good for intermediate files of non-linear video editing until they die.
