[SOLVED] Ready NAS Duo unaccessible after a resync
Hello, A few days ago, I've received a warning about a resync that have to be done on the NAS I clicked on it, This warns me about the background task and the fact that the NAS will still be acces...
Its a count of sectors that couldn't be read - if the errors had happened on a write, they would have been reallocated. So a small non-zero count is the same as a small number of reallocated sectors. Of course in both cases there are potentially a lot more failures with sectors that haven't been accessed recently. Also, disks can misbehave in ways that don't show up as horrible SMART stats. So if people are seeing hangs/poor performance, etc. then the disk might well be bad even if the stats look decent. The threshold for replacement is to some degree a personal decision (like most risk management).

But this case is not in the gray zone - ~525 pending sectors means the disk is bad.
