Question Changed hardware, now drives will not read.

But if the issue is the diode, which would make a lot of sense given both HDD’s failed simultaneously, would it then not be smarter to get a technician to fix that and then try another PSU before doing a fresh install?

With this new hardware, you need to do a new OS install anyway.

Yea, you’re right, I just cba a fresh install again but it is definitely a good idea.

Buy a cheap digital multimeter for US$10 or less. Then measure the voltages at the end of the SATA power cable.

As for the diodes, you can simply snip their pins with flush cutters. The drive can work without them, albeit without continued protection. It's all in my FAQ.
