How do you use a multimeter to check your thorny drive?

The solely check is the voltage going to the hard drive from the power supply.

These voltages are 5v and 12v.

Because it is a hermetic unit you cannot test the resistance of the motor.
Just what are you trying to do? You can check the voltage across components, you can only check voltages. You inevitability some knowledge roughly speaking testing electronics, otherwise you can ruin the HD. Such as the formulas vital, to interpreting the results.
STOP dont touch it, if you dont know what you are doing. the static alone could ruin your computer.
you dont.is like you use an electric meter to count your gas usage.
You wouldn't. If you aren't sure that your drive is getting plenty power then you would use the multi-meter on the proper pins of the power connector.
