Partition 4 is an "easy" one to resize since it's just the extended partition 
and doesn't have a filesystem of its own.

Partition 5 is formatted with ext3.  parted isn't liking this but i think 
that's because it's having trouble resizing the ext3 filesystem, rather than 
because it can't resize the partition itself.

Is the filesystem mounted at the time?  Maybe it can't be live-resized?

Cheers,
Mark
