[Solved] Sonar x2 onto external hard drive

.You don't put the program onto a second hard drive, you put the audio on the second hard drive.  I have Sonar 2 and 3 on my main drive.  I use a HP Envy 15 laptop, I7 chip, meaning 4 cores 8 threads. 8 gig of ram, so 64bit.  I use an external hard drive in a dock, better than those enclosed ones because of heat and power.  I haven't real have to push the thru-put but I get 24 tracks easily enough and I'm still using a USB2 dock so with a USB3 dock I suspect the skies the limit...or more than enough for most peoples needs.

The sonar program is not that big. It will fit on your drive of your laptop. If its that full, where a program cannot be installed, then do some house cleaning or replace the laptop drive because you'll have no room to really  do anything with it, if it cannot fit Sonar.

Thanks to all for the quick response. I should have known that the registry is involved.
This info is what I needed.
