It's a filesystem issue. From the parted documentation:
----------------------------------------------------
Parted has support for these operations:
# Filesystem detect create resize copy check
# ext2 * * *1 *2 *3
# ext3 * *1 *2 *3
# fat16 * * *4 *4 *
# fat32 * * * * *
# hfs *
# jfs *
# linux-swap * * * * *
# ntfs *
# reiserfs * *5 *1,5 *5 *3,5
# ufs *
# xfs * NOTES: (1) The start of the partition must stay fixed for ext2, ext3
and reiserfs. (2) The partition you copy to must be bigger (or exactly the
same size) as the partition you copy from. (3) Limited checking is done
when the file system is opened. This is the only checking at the moment.
All commands (including resize) will gracefully fail, leaving the file
system intact, if there are any errors in the file system (and the vast
majority of errors in general). (4) The size of the new partition, after
resizing or copying, is restricted by the cluster size for fat (mainly
affects FAT16). This is worse than you think, because you don't get to
choose your cluster size (it's a bug in Windows, but you want
compatibility, right?). So, in practise, you can always shrink your
partition (because Parted can shrink the cluster size), but you may not be
able to grow the partition to the size you want. If you don't have any
problems with using FAT32, you will always be able to grow the partition to
the size you want. Summary: you can always shrink your partition. If you
can't use FAT32 for some reason, you may not be able to grow your
partition. (5) Reiserfs support is enabled if you install libreiserfs,
available at http://reiserfs.osdn.org.ua. (It is likely to be availabe soon
from www.namesys.com... tell us if/when this happens!)
