I know that recent versions of Partition Magic will do what you want. 
And FIPS might, also.  But I'd do the following instead:

  - Backup all user data.  For CDRs, you're looking at less than 
    ten disks even if your /home and /dos partitions are completely 
    full.  Included below is a CDR-backup "cheat-sheet" that I wrote 
    for students in our lab.

  - Re-partition with a better layout and re-install.

This approach allows you to re-format the disk with confidence.  And its
*always* a good idea to have backups.

# === CDR-backup "cheat-sheet" ===

  #  Make ISO9660 file system with Rock Ridge (Unix) and 
  #  Joliet (MS-long-filenames-crap) extensions and follow 
  #  any soft links:
  mkisofs -R -J -f -o  file.iso  /path/

  #  Same as above but instead preserve (don't follow) the 
  #  soft links:
  mkisofs -R -J -o  file.iso  /path/


  #  Mount the ISO image using the loopback device to test 
  #  that it did what you wanted (got all the right files):
  mkdir ./test
  mount -t iso9660 -o ro,loop   file.iso   ./test
  cd ./test
  ls
  cd ..
  umount ./test


  #  Burn the ISO image to the CDR:
  cdrecord -v -speed=4 -dev=0,0 -eject    cell_990920.iso
  cdrecord -v -speed=8 -dev=0,0 -eject    cell_990920.iso
  cdrecord -v -speed=16 -dev=0,0 -eject    cell_990920.iso

  #  Re-Burn a CD-RW:
  cdrecord -v -speed=2 -dev=0,0 -eject blank=fast  pub.iso

  #  Backup a directory larger than the capacity of a 
  #  single CDR:
  tar -cvf - /path/to/backup/ | gzip | split -b650m - bkup.`date
'+%Y%m%d'`.tgz.
