Hey guys, your opinions please..
I was given a clicking hard drive to copy some files off. I plugged it into a Sata to USB adatper which I have used many times over 2 years without problems with many different drives (this was the first time in my new rig though) .
As I plugged the adapter into the usb port of the pc (which gives power to the adapter and spins up the HDD) it fried the HDD board within seconds as smoke literally came out drive. I immediately unplugged the HDD and within a few seconds my computer shutdown too and refused to start again.
Trying to get the board to power up, I have tried
- Unplug all devices and trying to boot
- Resetting Cmos / taking out battery
- Trying a different PSU
So I believe the board is DEAD as the green light is on but the case power and the onboard power button still does nothing. Unable to test CPU or memory but Gfx card has worked ok in my old rig, phew.
So what gives? I want to avoid this happening again by finding the culprit.
The only thing I've found is that the molex that goes into the USB to sata adapter has the +12v and +5v switched (no colours, tested with a multimeter) can this cause it? but doesn't explain why its worked absolutely fine up until now.
My build details are on the side, any thoughts appreciated..
Adapter looks exactly like the one below:
