Trouble with WD1501FASS

When I access the drive it takes about twenty seconds to spin up and I get a “not responding” message.

Is there anything I can try to fix this?

Thanks!

How many hard drives are installed and what is your power supply make/model/capacity?

Have you run WD Data Lifeguard diags?

I have two Vraptors and a Hitachi 2TB

PSU is a Thermaltake 850 .

I will run the WD Data Lifeguard diags

which drive is taking so long to spin up?  and is it the system drive or a secondary drive?
