I thought ext2fs was good at keeping files contiguous.

ext2 is good at keeping files contiguous, but remember the empeg filesystem is a pretty strange one: a relatively small number (compared to the average unix filesystem) of very large files.

The 24% fragmented means that 24% of the files have at least one fragment. I've seen much higher percentages on my empeg, but there's no problem - for there to be one or two (or even more) frags in a 4-6Mb file is not a problem. The HDDs read at more than 100x the rate needed for playback :)
