3 DVD drives on the same bus

I have a Windows 7 PC with 3 DVD drives. Imgburn shows them as connected to 3 different SATA busses: [2:0:0], [3:0:0], and [4:0:0].

After upgrading to Windows 10, all of them ended up on the same bus, [2:0:0], like this:


Why did that change? I tried connecting them on different SATA plugs, but they are always shown on that [2:0:0] bus. The thing is, I really need them to be on different busses, because of a particular requirement of a legacy application I use.

Things I tried:

- Replace default Microsoft SATA driver with ATI driver. It didn't solve anything.

- In BIOS settings, changed SATA type, from AHCI to Native IDE. It did kinda work, now they are shown in different busses, [0:1:0], [1:0:0] and [3:0:0]. But now I'm not using AHCI anymore, I don't like that solution.

I don't know what problem you have. I have two drives on SATA0 and SATA1, the way they should be. I can burn to multiple drives at the same time with Nero (no other burning program that I've tried will burn to multiple drives at the same time).

Imgburn shows my two drives as "4:0:0" whatever that means.

Thank you for your response. Is that on Windows 10 or Windows 7?

That is Windows 10. I have a dual boot, Win 7/Win 10 and the drives work the same in Win 7 (and they worked the same when I had Windows 8/8.1).
