1 3.5” HDD 5 Volt sensor reports zero with TechTools
3.5” HDD Thermal Sensor iMac 21.5-inch Late 2013
New TechTools has a sensor test. My Hard drive comes back with zero volts and says the test failed. Any Ideas if this is truly a problem?
I’m not having problems. Running TTP 8 off of my main drive. TTP support had no answer. Apple Support had no answer other than take the iMac in for testing. I was just wondering if anyone had an answer before I lugged the iMac in for testing. I do have Apple Care.
Es esta una buena pregunta?

If you have AppleCare, get it in before it expires!

I have had this issue with two identical late 2103 models but what I can’t figure out is, if no power is getting to my newly replaced SSDs, how are they working? Have I stumbled upon a way of supplying power to solid state drives from thin air?!
I think this is a false warning but it would useful to know what Micromat makes of it. I was using Techtool Pro 12 when I first experienced this but EtreCheckPro didn’t pick anything up and as the machine seemed to be working fast with no apparent problems, I let it go.

Micromat's TechTool is a useful tool, but using the onboard diagnostics is what I would start with.
I've seen other wacky errors with it. Often an updated version would address the issue.
