Sampels on secondary hardrive?

Hey. Have just replaced the standard hard drive in my Macbook Pro to a SSD 250GB hard drive. I also bought a hard drive of 750GB and put it where the disc reader usually sits. There, I was going to have all the samples. Now when I sit with a big pile of installation discs and just started installing Supererior Drummer and choose to do it on the secondary hard drive, I get this error message. "Could not copy eula.html file". Obviously I have to install the entire library where OSX is installed (250GB SSD). I could install all my Toontrack library but, I have included Ivory, Hauptwerk, Fable Sounds Broadway Big band and so on. This course will obviously not fit on the SSD drive and it would be very stupid.

Is it possible to install the software on the secondary hard drive?
