WD15EARS not being recognized by Deepspar but recgzed by OS

[frachoi]

I have a Western Digital Caviar Green drive WD15EARS drive that went bad. I swapped PC Boards from a donor drive and plugged it into my Windows and Mac systems. The OS recognizes the existence of a drive but doesn't read the right size or sectors. Even my Deepspar does not pick up the device. I've seen postings where the firmware or configurations are stored in the SA. Does anyone know if this is the case for this drive or do I need to swap chips? If so, there are 3 chips on the board so if you can identify which chips to swap I would be grateful.

You can't just swap PCBs on those drives. You should know this.

Is the thread real or is it a joke ?

If there is an unpopulated location at U12, then the adaptive data will be internal to the Marvell (?) MCU. From your description, it appears that your board has an MCU, motor controller (SMOOTH ?), and an SDRAM.

What is the fault with the original board? It may be easier for you to repair it than to try moving the adaptive data to your donor.

He can easily program this information with his other tools. But maybe people are just purchasing DI today for no reason but to have one. Who knows.
