To put the 15 gigs of space to better use :)

Googling the problem turns up several people who **claim** all that has 
to be done is to dump the existing partition record to a text file using
sfdisk...changing the 4 to a 3...then telling sfdisk to recreate the 
partition by feeding it the modified text file. However you note I said 
**claim**.

    No, I reclaimed 15 GIGS of space. Gparted first moved the Debian 
partition ( it was at the end of the disk, than created a new file 
system in the recovered space, which was added to the Debian partition.
