With my new DSLR/RAW shots, I've bloated iPhoto to over 105GB for just over 20,000 photos. Was doing housecleaning, deleting files and the "aw sh*t" moment hit where I deleted some i wanted. Went into TimeMachine and did a Restore to my external 2TB HD (FW800) as temp place. Now, when I went to delete that 105GB file started last night 10:30 pm, here 7.5 hr later: still churning away.....wtf did I do wrong??
