Replace HDD4 by "Hot-swapping" it with a good drive. Claim warranty from Seagate for this failed drive.

And the most strange thing is that the SMART warning have sometimes appeared just to after a day or so disappear. And this is not just on one disks, but these issues have happend with at least three disks during the NAS' lifetime.

Nothing strange: Current_Pending_Sector (for example) is a *volatile* SMART attribute - every current pending sector can be either fixed by HDD-based controller "intelligence" (ie. error recovery processes) or replaced from the spare pool. In either case, the Current_Pending_Sector number does decrease again.

Not a NAS issue at all.
