PCB failures (Such as Seagate PCB 100781943) 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.
