PCB failures (Such as Hitachi PCB 0A75655<\/b>) 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.<\/p>\n

compatible board, what do i have to match to find a donor PCB ??? Will any board from a HTS723232A7A364 work as long as i load the NVRAM infor from the broken PCB on the new one, or do i have to find a more specific PCB ?
