PCB failures (Such as Hitachi PCB 0A52020) affect thousands of hard drives every year and often result in permanent data loss. A hard drive may suddenly fail to power on, and a computer may not detect that it is plugged in. Some failed hard drives will also show up in computer BIOS with incorrect brand/model information. PCB failures can also cause physical issues such as read/write head failures, and many PCB failure symptoms overlap with the symptoms of other physical hard drive issues.
Some emails from customers of Hitachi PCB 0A52020 failures are listed below, along with tips for replacing & repairing.

Q: HTS541680J9SA00 PCB compatability question (water damage)
I have a HTS541680J9SA00 that had water marks on far corner of the PCB (laptop suffered a water spill) The drive spins up but does not detect no burn marks, no water near breather holes Board is HTS541680J9SA00 P/N 0A53318 MLC DA1905 PCB 0A52020 DA1672C 1P3T My question is, is this a potential donor board HTS541680J9SA00 P/N 0A53318 MLC DA1905 PCB 0A52020 DA1672C and would swapping the PCB to this donor involve an NVRAM reflash, ie is it possible to extarct it despite not being detected?
