Same story as everyone else who has done this, sent 19v through an external drive bay and fried a WD RED WD40EFRX, using a Klein Multimeter CL800 and some forum threads i have identified these diodes/fuses to check resistance on. The values are below.
Sounds like my issue here is D2 and D4 are shorted, so my solution is to remove the 2 diodes and the drive should work again? or do they need to be replaced?
Many coaxial power adapters have different voltages while being the same size, the mini pc i had this external bay hooked up to was 19v, and the bay was 12v, while moving it i accidentally plugged the wrong one into the external bay. Seems to be the case with almost everyone who has fried these.
I use the supplied PSU with my USB storage boxes. My 5-disk Orico box has 12V 6.5A which handles hard disks fine.
The PSU connector is a 4-pin DIN type connector which makes it unlikely to be confused for barrel or USB. The brick also has a blue LED to show its powered up as well.
My single disk box has a barrel connector but I put a tag on it and the brick has power label which some do not have.
I suggest also labeling power cables etc for safety.
