    Hello!

    This was my first time upgrading a HDD in a laptop, my Sony AR 520E had space for two. Neither HDD had what I'm used to as jumpers to set which one is primary vs secondary... they merely a specified spot to plug primary vs secondary into my laptop.

    My bootable C: is listed as secondary master while my backup D: is listed as primary slave. How do you change this so the C: is the primary master? Does it even matter?

    C: is a Hitach HTS722020K95 dc40 (Ide(0))
    D: is a Toshiba MK2035GSS dk02 (Ide (0)) [was factory HDD]

    The critical question is "does it matter?".

    The optical drive will be using one of those channels and you may get a theoretical performance hit if you are copy between two devices on the same channel. I say theoretical because the optical drive read/ write transfer rate will be the actual bottleneck. You would have a performance hit if both HDDs were on the same channel.

    If you are worried, run HD Tune on each of the HDDs to see the actual transfer rates.
