Some PGMusic hard drives come with a USB cable that has one drive side connection and two computer USB connections.
This boosts the power to the external drive.
Did you get one of these with your hard drive?
If not this may not be applicable, but if you did -
Have you tried connecting both USB connections on the supply side?
One connection handles power and data like a normal USB cable, the second connection supplies only power, from what I understand.
Thanks rharv. I do have two USB plugs on one end (the computer end). I have never used the 2nd one. I have two free USB ports on the front of the computer. So I should plug both of these in rather than just the one. I will give that a try and see if it solves it. I guess I will leave it plugged in a while to give it a bigger test so I can find out.
Tomorrow morning I am going to dig into an web page I found regarding noisy fans. First thing is a dust cleaning with a blower. If that does not solve it I am a bit reluctant to stop the fan while the noise is occurring to determine which one it is. Maybe there is a trick here. Maybe just blowing on it will change the dynamic and tell me.
