Hello,
I have three Ministacks attached to my Mac mini Server. The drives in two of them are continuously overheating. They do not spin down properly, when inactive, while their fan is off.
Setting is as follows:
- Mac Mini - USB2 - Ministack V3 2TB HGST Ultrastar
- Mac Mini - USB3 - Ministack 2012 4TB Seagate Enterprise Capacity
- Mac Mini - USB3 - Ministack 2012 3TB Seagate Enterprise Capacity
Both Seagate HDDs do not spin down properly.The strange thing is that they appear to spin down, while the Ministack V3 is still working. But when the Ministack V3 goes into standby, both Seagate Drives start spinning, while the Ministack 2012's fan remains off. I found out, that when in standby, when SMART is queried, only the Seagate drives in the MS 2012 turn on and later do not spin down. I had 2 disks dying this summer and try to figure out how to improve the setting.This is why I have the following programs installed:
- iStat
- DiskWarrior
- Drive Genius
- DriveDX + SAT SMART Driver v0.8
In order to eliminate SMART from the equation I turned off HDD monitoring in iStat, eliminated external HDD monitoring in Drive Genius and set DriveDx to 8 hours testing.
I tried connecting them with firewire, but they did not go to sleep, but at least the fan kept running. When connected via USB they do not spin down. I checked at Seagate and the drives should go into standby after 15 min.
Can someone help?
Mac mini, OS X El Capitan (10.11.6), MiniStack, USB3
