Hello.

Could somebody please make some educated guess on where the problem might be?

I have a secondary internal 500GB WD SATA disk that cannot be detected anymore.

It started yesterday, right after a major blackout. My UPS, for some reason (maybe battery?), shut down before I could get to the computer and shut Windows down myself.

Since then, I get a warning from the SATA378 TX2Plus controller to the effect that "BIOS does not find a proper hardware configuration" and the SATA BIOS is not installed.

During the scanning there is an occasional click from the hard disk and eventually Windows boots without this particular drive.

The SATA controller firmware is the latest I could find (1.00.0.33) as is the mobo's (Asus P4C800-E Deluxe, firmware 1024.001).
This disk is the only one connected on this controller which operates in IDE mode.

So what could the power outage have affected in this case?

The controller tries to find the disk so I suppose some part of it is working properly.
The disk never had a problem and is quiet except now and then when the controller tries to send some initialization commands.
The cables look fine too (I reseated them).
Resetting the BIOS to defaults and switching the controller back to IDE mode didn't have any effect.

How should I handle this?
Could the controller be partly working (how to tell?) so I can plug in a PCI controller or is it the disk itself that's a goner?
I'll be taking the disk to try it in some other computer once the storm passes but it would be nice if I could try and cure it myself first.

Thanks in advance for any pointers.

I resolved the issue myself after all.

The problem was with the onboard SATA controller. The disk worked fine in another computer.
I just bought an addon PCI SATA controller and all's well.

good, thx for the update.
