my ssd is a 64GB.
heres the easiest way I can explain it. I put my OS on the SSD for sure. I also want one game on it. So I will reinstall the game to the SSD. However, I have voice communications such as mumble and teamspeak that I sue for gaming. I do not want these on the SSD. But I have to put them on there otherwise I cannot use them, correct? Even though mumble and TS are on my old HDD, I cannot use the application unless I install it on my SSD right?
No, you can install those on the HDD. Windows doesn't care where, as long as it is designated during the install.
Reinstall, and select Custom or Advanced during the install. That will allow you to select where it should go.
