The external drives are 3x the size of the internal. I understood to add a new drive when Time Machine has filled up its existing external is so the photos do not get overwritten. The photos would no longer be on the internal drive. I do not understand why I could not retrieve the photos from the first Time Machine drive once it writes to a second Time Machine drive. True that the first TM drive might not fill up. May not need to understand this until I get there. Am good knowing the shots are on the second external drive with SuperDuper or other program. As you use DVD backups - some work will be backed up on DVD as well. Thousands of photos being moved off the computers internal is new for me. Once the deed is done - a nice glass of wine will be enjoyed. I appreciate the tips, info and experience Lea. - Bobbie On Tue, Dec 27, 2011 at 10:17 PM, Emily L.
