I have been having issues where the bit you put the disc in won't open when the disc drive is connected with a SATA data cable to the motherboard (I have tried cables for SATA one, two and three) and i'm wondering if it has anything to do with the SATA type on the disc drive. My motherboard is an MSI 990fxa gaming series, which is supported by SATA 3 if that helps at all.
