Time machine removing backups too aggressively?

    I have a 90 GB internal drive in my MBP of which about 80 GB is occupied. I have a 120 GB external FW drive dedicated to Time Machine. The external drive still has about 20 GB free space. I've had TM configured for about 3 weeks, but I noticed today that the oldest available backup is from last night. That seems strange to me - I would think I should have at least a week's worth of daily backups, and probably a couple of weekly backups since the external drive isn't feeling any space pressure at this point (so no need to remove old backups to get below the limit). I deal with some relatively large image files (20-50 MB), but don't change very many of them on any given day, and even then I'm not really changing the base file since I'm using Lightroom. Any ideas?

    The only thing I can think of is that may there was a particularly large incremental from 2 days ago, and TM found that deleting the weekly's wasn't enough, and had to keep deleting daily's until yesterday's to free up space. But that would be very odd, since I haven't done much of anything in the last few days.

    That doesn't make much sense to me. I noticed the other day that the Time Machine interface wasn't letting me go all the way back through my backups. But if I looked on the backup drive they were still there. Later, the interface let me go back. Maybe I rebooted or reconnected the drive, I don't remember.

    Have you looked at the files on the drive using Finder to see just how many sets you have?
