PCB failures (Such as Samsung PCB BF41-00354A<\/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 HN-M101XBB USB<\/b><\/p>\n
Standard reflowing procedures didn’t help I tried to solder SATA connector to PCB, drive started to spin, but booting was failed I consider to try a donor PCB swap Is the Seagate ST1000LM024 will be a good replacement? Donor drive PCB is BF41-00354A, and have a same elements except the USB controller If so, do i need to swap firmware chip to donor PCB? Any other thoughts and possible solutions are welcome ) Thank you<\/p>\n
