PCB failures (Such as Samsung PCB BF41-00314A<\/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 or making any noise.<\/b><\/p>\n
removed the TVS on the PCB and jumped the fuse Still no results Right now I’m looking to get a new PCB for this drive I plan on performing the chip swap as well, my only concern is PCB compatiblity I see model numbers for PCB’s such as BF41-00314A 00 S3M Rev 03 R00 and BF41-00303A 00 I’m just not sure which ones should be compatible I’ll post some pictures of my hard drive for reference iimgurcom\/eE289jpg iimgurcom\/ttyAAjpg iimgurcom\/jFV5vjpg Thanks<\/p>\n
Q: Samsung HD204UI PCB BF41-00314A 00<\/b><\/p>\n
Hi everyone, thanks and sorry for my bad english in advance Due to an error i applied 12v instead 5v and 5v instead 12v to the power contact of my HDD I tried the damaged HDD with other PCB from the same model as mine, result the hard disk spins, but it’s not detected by BIOS or SO, i don’t know if this is due because of a distinct firmware (one PCB is from 2011\/09 and the other from 2010\/10) Anyway i bought other PCB in a website (i don’t know the date of fabrication) of the same model but <\/p>\n
Q: Swapping PCB on Samsung HD204UI?<\/b><\/p>\n
with a working one), it is exactly the same damage as shown at forumhddgurucom\/viewtopicphp?t=24676 , where it was identified as being an STJ009 MOSFET Now I happen to have an identical drive with the same PCB (the codes match BF41-00314A 00), so I’m thinking I should be able to perform a PCB swap However, I read from www com\/hard-drive-pcb-donor-match , specifically for Samsung drives, that “Chip transfer \/ swap or similar services could be required <\/p>\n
Q: Samsung HD204UI (BF41-00314A PCB) problems<\/b><\/p>\n
didn’t spin up, not detected in the BIOS After a lot of poking about with a multimeter I concluded that the PCB was dead, and that there was a reasonable chance that a replacement PCB swap would get the drive going again (PCB serial No is BF41-00314A) After furnishing my colleague with my findings and the number of the PCB, he decided it was worthwhile and procured a second hand one from Hong Kong (his decision, not mine) The board arrived today, nothing outwardly wrong with it, more <\/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
