Recently I installed a new PSU into my PC. It had modular cable connectors and I mistakenly tried to use SATA power cables from my old PSU with it. The cables had the same connector on PSU side but different pinout: +5V and +12V were swapped and it caused 2 hard disks to die.
The Seagate drive prevented the PSU from starting because of possible short circuit inside, but the other WD drive did not although it was not spinning also.
I removed the PCB from my WD1001FALS drive. It had a burn damage on U1 chip (Smooth chip). I also tested the TVS diodes and one of them was dead (the one for +5V input). I removed this diode and tried to power it on in spite of burned controller. Certainly, it didn’t work.
I would like to know if the drive is repairable after all these things that I’ve done to it. For example can I get the U1 chip replaced or there are some other damaged components there for sure? And will the data still be readable after the repair?
Thanks in advance.
