My external HDD suddenly wont power up, there is a blue light on it though. I checked every possible solution like device manager, computer management, etc there is NO TRACE of my HDD appearing on windows. I tried all my USB Ports.

The HDD works on my laptop no problem, but not on my PC.

Strange thing is when I turned off my PC with the HDD plugged in, the HDD starts to power up 100%, then when I turn the PC on again, the HDD powers down?
