My TB Duo is always left on and connected to the iMac
The room has aircondition at a temperature of 26degC
Even when my iMac is asleep, the TB Duo fan can spin up and the drive becomes very loud
On a few occasions, the amber light had come on and I had to switch the drive off.
This has been happening since day 1, except now I don’t see the amber light so often.
What is the problem here?
