PCB failures (Such as Seagate PCB 100398689<\/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: PCB BAD ST9160821AS<\/b><\/p>\n
Hi to all!! ?PATIENT IS ST9160821AS FW:3.BHE PN: 9S1134-022 SITE: WU (PCB 100398689 REV C)DONOR IS ST9160821AS FW:3.BHE PN: 9S1134-022 SITE: WU (PCB 100398689 REV C)pcb bad. I changed pcb with one good pcb.RECOGNIZED HDD AND FOR THE MHDD, WHEN READING MEDIA (F2-SCAN) READ WITH SOME BADS BLOCKS NOT READ (DE PCI) 2.21IMG FOR COPYRDMA (VERY SLOW AND AFTER THE ERRORS (BUSY)HELP-ME!! ?HAPPY CHRISTMAS!!! ?<\/p>\n
Q: Where to buy HDD donor parts?<\/b><\/p>\n
donor parts from? Are there any websites or companies that specifically deal in finding the correct drive? Drive Details below – Seagate Momentus 54003 – 160GB – SN 5MA17343 – Model ST9160821AS – PN 9S1134-506 – FW 3ALB – Date 07373 PCB – 100398689 – REV B (100398688 K 373380FR) The drive spins up fine but it has a constant ticking, it will spin up, click click click (clicking could be continuous but it can occasionaly beep too) eventually it will give up and then spin down <\/p>\n
Q: My plan for trying to recover a Seagate Momentus 5400.3<\/b><\/p>\n
I may record the sound and post it later if it could help As much as this sounds like mechanical damage, I’m willing to try a PCB replacement + ROM swap, just to see if it’s not a blown motor control IC or somesuch The PCB in question has “100398689 REV C” etched on it, which is my first question Is any PCB with that number a suitable replacement? As I see it, this could be a generic PCB onto which a specific model’s components are then mounted, but I wouldn’t know Furthermore, <\/p>\n
Q: Seagate st9160821as DEAD\/No power\/No signs of life<\/b><\/p>\n
the caddy and plugged it in to a PC PSU, but still no sounds\/signs of life could be heard That’s all I know \/ don’t know – Seagate st9160821as (160GB 25″ HHD) ========================= [Picture A] PCB serial # 100398689 REV C Components Tested none yet This PCB has very few reference designators Any ideas where I should start testing? I think I should definitely test components on the 5V circuit, as this drive has only been used in an usb caddy Should <\/p>\n
