Hey folks! Thanks for checking out my post... I needed some extra HD space, so I deleted the 1.5TB hard drive I've been using as my TM backup and thought I'd partition it and re-run TM in the partition. I erased the drive and created two partitions: 1TB and 500GB. I transferred 250GB of files to the 500GB partition and then set-up the 1TB partition to be used as the TM backup. I ran TM and it told me that it had backed up 264GB...the problem is that my internal HD has 478GB of data on it...so...something's not being backed up. My only thought at this point is to erase the HD again, re-partition it, and run TM first...and then transfer the data to the other partition. Any thoughts before I begin this process again would be much appreciated!
