I expected this.
I also have multiple controllers in my box.
In your case, it’s probably not the serial ATA one. SH-S182D is not a SATA device.
You can uninstall the other controller if you have only plug-and-play devices attached to it.
But we’ll play it save.
Open Device Manager similar to this, and double-click the channel that’s in PIO mode.
The properties window will open up in a couple of seconds.
In the properties window go to the Advanced Settings-tab and check the current transfer mode to be PIO. (Playing safe here.)
Then go to the Details-tab and note the red underlined number. (Leave the properties window of the channel opened.)
Now you’ll have to find the corresponding controller.
I clicked the second (from the top) primary channel, so normally I would have to click the second (from the top) controller.
I did and went into the Details-tab, and chose “Bus Relations” from the drop down. It shows the IDs of the Primary (ending in 0), and Secondary (ending in 1) channels.
One of these two channel IDs MUST match the (red underlined) “Device Instance ID” of the channel.
Otherwise you have the wrong controller.
The bus relation is in the color of the red and blue squares.
When you have a dvd-drive and hard disk attached to the same controller and both are plug-and-play, you can safely uninstall the controller.
All will be re-detected and installed.
