I own a Macbook pro 15'' (late 2008; Maverick) and have 2 drives in it, one SSD with Bootcamp and one HDD with Mac OS X. Since i don't need windows anymore i thought i could make a Fusion drive out of it to speed up things a little bit. But I'm not quite sure how to do that the best way, i thought about this procedure: 1) Create a bootable copy of my HDD with Carbon Copy Cloner on my external USB HDD. 2) Boot from it and format SSD and internal HDD. 3) Create the Fusion Drive with terminal commands 4) Write back all data with CCC to the new fusion drive. 5) Boot new fusion drive and complete system should be the same, with faster write speed for often used tasks I'm asking myself if it is possible to write back the complete Backup with all system files/settings while running the system from this backup?
