I have selected that my /home files should be transferred to the new partition.
How did you transfer your home files ? using copy or using move ?
There is a chance you
copied your files from /home to /newpartition and later you mounted /newpartition under the directory /home,
this way your original home files are still there (using root partition space), but hidden by the newly mounted partition.
Log in as 'root' and umount /home partition, then look in /home directory ... alternatively boot from a LiveCD and check the content of both partitions from there.
