Dobry wieczór,

Mam serwerek na standardowym Slacku 13.0 architektura x86 a na nim
programowy RAID1 oparty o jajkowy mdadm. Dyski (2 szt.) jakie tam siedzą
to 1TB WD Green-y: WDC WD10EARS-00Y5B1.

Do testów powierzchni (tylko /dev/sdd, ale o tym niżej) jakie robiłem
wykorzystałem: MHDD, WD safe guard (long), badblocks -w. Nie wykryły błędów.

Do wyników S.M.A.R.T. przyczepić się nie mogę:

Wszystko jest jeszcze na gwarancji tylko nie ma się do czego przyczepić.
Ma ktoś jakiś pomysł?

Pozdrawiam.
