PCB failures (Such as Seagate PCB 100274360) 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.

Q: which is more important, IC# or FIRMWARE# for seagate

I can find a pcb with the correct firmware, and I can find a board with the correct IC# but not both at the same time. Is it possible that one of these will work?Thanks, BenMODEL: st3120026aPN: 9W2083-306CONFIG: D4H-02FIRMWARE: 8.54DATE: 05164SITE CODE: WUIC: 100274360MOTOR IC: SH650PCB: 100306044 rev a

Q: 7200.7 Please identify missing element.

The chip was broken in half (before completely peeled off), black plastic remain suggests resistor. I need to know value of this resistor. I have similiar 7200.7, but MPU is ST, not Agere. Strange, on this PCB connected to the same MPU pin is capacitor (brown), but I am sure it was black.Here are PCB details and photo:ST3200822A 72007F/W 3.01 APLUS S.07PCB sticker: 100299703MPU:AGERE 4490D6100274360-74100300639-83Motor chip:Ti 980 BSH6950
