PCB failures (Such as Samsung PCB BF41-00315A<\/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 HM100UZ – need compatible PCB<\/b><\/p>\n
Hi friends,I need confirm what PCB are compatible for Samsung HM100UZ with PCB: MT2U_AS_REV.01 BF42-00338A with MCU 9122.I try already PCB with 9122 00315A and 00320A – not work, motor not start.I suppose that 00322A from HM100UI should be compatible, but I do not have it.Anyone check it already?<\/p>\n
To repair a failure board, the simple way is swapping the failure board with a replacement board. Donor boards on HardDriveParts.com are listed below:<\/p>\n
