I have fitted a WD20EADS-00R6B0 into a ICY BOX IB-362 series external enclosure.
It is connected by esata to a Dell XPS 420.
The problem is that the drive never spins down even when there is no data access for hours.
The temperature slowly climbs to around 50C with a ambient room temperature of 26C.
Should I be concerned and is there a fix?
