I recently purchased and precleared a new WD20EARS drive without any issues. After formatting and adding the drive to the array, Unraid Main shows the temperature of the new drive as 0degC. Unmenu main, however, gives a valid hard drive temperature. I searched the forums and found this come up in a few threads, but could not find any resolution. Is this a problem with the HD I should be concerned about? My array contains 2 other WD20EARS drives the correctly report temperature in both Unraid main and Unmenu main.
