I have been having some weird effects with my relatively new WD Green 3Tb(bought in December 2012). Just sometimes reading from it stalled and my computer could not read anyjthing from it for minutes. After a reboot it could not be detected. It might be during overheat because it was installed in front of 15k SAS Seagate drive, the hot air from which used to pass through my WD, probably. However, when I run smartmontools (I use Linux), the temperature was around 40C. Anyways, I saved data, reinstalled the drive into different bay (now WDC warms Seagate!), reformatted it and started to use it again. I have got the following SMART data

Any smart SMART experts? I am a SMART-peasant, know only temperature parameter and seek-err-rate. Is the drive doing OK now?
