Help! Added external 60GB SSD boot drive. How do I use internal hard drive as storage? Im able to navigate to it in the finder and save files, but when I try and backup using time machine (to another external HD) its not recognizing the internal HD as part of the backup. I kept OSX on the internal iMac HD just in case the external SSD gets removed I can still boot up my mac from internal drive. Seems like i have drives all over the place and I want them to work as a whole, and all backup as one under my user. Am i doing this correctly?
