Can't connect 3 drives at once, only 2 work at a time.

HI,
My older Gigabyte H67MA UD2H mother board has 2 SATA 3 ports and 3 SATA 2 ports.
I had an HDD and Bluray drive installed and I want to add a new SSD.
The BIOS only "see" the drives connected to ports 0 and 1 (the SATA 3 connectors), and I can't get all 3 drives to work at once - no matter which drive I connect to the SATA 2, the BIOS doesn't see it.
only drives connected to the SATA 3 ports work.
Ichecked the cables, they are all fine.
is there a solution or can I only connect 2 drives at a time with this MB?

CPU: intel i5-2400
MB: Gigabyte H67MA UD2H
Samsung 860 EVO SSD
WD 1TB HDD
DVD/Bluray drive

Check in the bios, if the sata2 controller/port is activated. Option should be somewhere in the chipset settings.

I Checked all the options the BIOS and didn't see such option. Is there a specific name for it?

Ok, I think I discovered the problem

...design problem ... The flaw may result in 3Gb/s Serial-ATA II (SATA II) ports degrading over time, in the words of Intel "potentially impacting the performance or functionality of SATA-linked devices such as hard disk drives and DVD-drives."
The issue is specific to SATA II ports within the Intel P67 & H67 chipsets only.
