This table is from the Samsung Magician 4.3 installation guide:
So any AMD chipset board (like yours) that has an AMD SATA driver installed (no idea what you have) is not supported by the Magician 4.3 software. I've seen this issue in other forums many times with AMD boards.
What SATA mode are you using, what is it set to in the BIOS?
The table states that using a Microsoft SATA driver with your AMD SATA chipset should be compatible. So that would be the potential fix.
I say potential since your AMD SATA chipset is older now, and might not be compatible. Do you have the AHCI option in the BIOS for the SATA mode?
