Mountain Lion on new SSD, other files on other internal HDD
I've been using Mountain Lion from day one, but would now like to put it on a new SSD drive in my Mac Pro.
All my working files (music, photos, movies and emails) have all my files backed up on other drives, so want to do this as a clean install (and not migrating any other files over at the moment, other than emails).
I want to have ML on the SSD drive including all applications I use, but to have Documents, Movies, Photos and Downloads on hard drive (non-SSD) as have more capacity on this. When needed, I will transfer the files to this hard drive from the other drives they are on now.
How can I do this by keeping the majority of my Home folder on another drive.
Any help and advice would be greatly appreciated.
Thanks in advance.
