I gave my sister my old computer. Everything was working fine when it left with her, but now I'm getting a "secondary master drive atapi incompatible" error during boot. It will boot up fine and works fine, but its a little intimidating for her since she's not a computer person.
There's only one hard drive connected and its SATA, and no CD/DVD etc. The only thing that's changed since it was running perfectly is its location and also removal of the DVD drive.
