Wondering if anyone can help: I have a Newer Tech Software RAID setup with three drives in my mac pro (2010, yosemite)....Lately, it has been ejecting on its own periodically and I get the error message. The only fix is to restart the computer. Checking the event log, a sample of the alert messages are as follows: Disk 'WDC WD2002FAEX-007BA0-WD-WCAY01016815' (Location: Device_1_4) temperature is higher than threshold. 2016/2/10 9:40:26 Disk 'WDC WD3003FZEX-00Z4SA0-WD-WCC13RANC44S' (Location: Device_1_1) temperature is higher than threshold. 2016/2/10 9:24:48 Disk 'WDC WD3003FZEX-00Z4SA0-WD-WCC13PHKZYFZ' at Controller1-Channel3 failed. 2016/2/9 20:24:52 Device 'WDC WD3003FZEX-00Z4SA0-WD-WCC13RANC44S' at Controller1-Channel1 SMART test result: FAILED! So far I have tried monitoring the temperature by increasing fan speed on HDDs. Anyone have this experience or have any suggestions? Thank you.
