PCB failures (Such as Samsung PCB BF41-00359A<\/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

Q: Samsung HD103SJ Not Spinning Up<\/b><\/p>\n
not spin up I tried removing the TVS diodes again, but still no avail What should I do to get my hard drive working again? Is there something I can do to fix the existing PCB? or should i go for a PCB swap? If so where can i get the PCB (bf41-00359A-00 rev01 r00) (which also allows shipping to sri lanka) and do i need to swap out any chips on the PCB? Thanks in advance o<\/p>\n
