I am currently using a WD Passport drive in my MB which I created by cloning my old system. Anyway, it seems slower and to cut a long story short I want to go back to my original 250 GB drive. Ok, now at home I have a Time Capsule, and I have everything backed up to it, but I am not at home at the moment but still want to do this clean install. When I created this disc I am using now, it wasn't recognised by Time Machine as the same disc, could this be because I changed the HDD name from Macintosh HD to MacBook HD? I had to start again with my backups, which took an age to get going again, and of course I effectively lost my old data. So, my proposal is to clean install on my 250 GB drive (currently in a caddy and attached by USB), then use migration assistant to copy everything (including VMFusion) across. Will this then be recognised by my Time Capsule when I get home or am I going to have to start again?
