Das leuchtet mir ein.  The fragmentation wasn't too bad overall, but
the disk was getting very full and new writes were probably breaking
up.  The new notebook has 80G instead of 30 and of course there's very
little frag yet.

(It was only a couple of decades ago that 10Mb was a truly generous
hard disk size... ;)
