My new 2012 iMac doesn't recognize my old time machine backups. I did the migration assistant from the setup, but then it said my hard drive didn't have enough space. I was using 675GB of 1TB and it was an additional 675gb to back up the data and said that I only had like 188gb left. I then got a new 2TB drive and transferred the data to the new drive using this method http://support.apple.com/kb/ht5096 It wanted to back up the 675gb of data even after the transfer. Now the kicker is that I can't even access my old data through time machine or finder. Anyone have any ideas?
