If it was me I would try to image the 17Gb drive and save to
dvd and then repartition your drive like you should have in
the beginning. Now, the imaging only makes sense if you
dont have too much on the 17Gb partition, Ill leave that
decision up to you.
I think starting from scratch with a fresh drive, partitioned
and formatted is better than "Hoping" Partition Magic can
move all this data around and you will come away with a stable
system and no data loss or corruption-MO.
