Replace the controller? What do you mean? While you do have a SATA connector on your NUC's board, you have a low-profile chassis that does not have a drive bay to hold the SATA drive. Or are you talking about the mPCIe connector that allows you to use a mSATA drive?
So, my NUC pc is D34010WYK and, yes, have a drive bay to connect an HDD 2.5 inch, additional of the mSATA connector on the mainboard.
My issue is that from a time the HDD is not recognized any more. I already give an picture of the controller which I believe is not working properly.
Can I procure this component from INTEL, since is the manufacturer of this PC - D34010WYK?
Ah, you have a D34010WYKH, not a D34010WYK. That's the version with the hard drive bay.
These units were EOLed long ago. All stocks of the replacement I/O board have subsequently been exhausted. Someone was looking for one a few months ago. The development team could not find even a single board.
