@Elizabeth: oh no, that sucks too
This happened here before as well: renaming or moving something in explorer and ending up with lots of orphan files...
I love ACDSee but the thing I hate most in it is that there's no undo button! It would also be so much more efficient if the tags were automaticly added to the files meta data. I know Lightroom works like that and if I hadn't already built up such an extensive database in ACDSee, I would probably change...
@Erica: thanks for the tip. I'm just going to wait until I hear back from the store because the disk is still under warranty... It does look like it's the power supply that died. I'm hoping that changing the adapter will solve it!
@Rebecca: that looks interesting! If all else fails, I'll look into that!
