PCB failures (Such as Seagate PCB 100731495<\/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
Some emails from customers of Seagate PCB 100731495 failures are listed below, along with tips for replacing & repairing.<\/p>\n
Q: Seagate ST1000DX001 – DEAD\/no signs of life<\/b><\/p>\n
this is when the hard drives died; that’s what I was toldhat I know \/ don’t know – Western Digital WD10EARS-00VWB0 (1TB 35″ SSHD) =============================================== [Pictures A & B] PCB serial # 100731495 REV B Components Tested ?? – TVS diode? ON 6LF VNE46 This PCB has very few reference designators I have tested both diodes circled in ‘red’ and ‘blue’ (shown in picture B) The ‘blue’ diode has continuity, but the ‘red’ diode does not <\/p>\n
Q: Seagate SSHD 1 TB ST1000DX001 (FW: CC41) don?t spin.<\/b><\/p>\n
Hello everyone I bought in an auction 100 (yes, one hundred) Seagate SSHD 1 TB hard drives (ST1000DX001 – FW CC41 – P \/ N 1NS162-300 – PCB 100731495 Rev B) with exactly the same defect in all of them The discs don?t spin and nothing on terminal console Recorded data is unimportant, what I need is HDs to come back to life I did tests on the TVS diodes, 0 ohm resistors, everything is correct I put a PCB from an HD donor in some PCB <\/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
