I just installed a new hard drive (320GB) and RAM in my mac mini. I was able to reinstall OSX from my Time Machine external HD with the last full backup (dated a year ago). I cannot get the incremental backups to be recognized. TM did a full backup with the new machine. I fixed permissions of both new drive and repaired TM drive. Rebooted. Still no joy. Can anybody help on restoring TM incrementals?
