Thanks for the report, but what version of parted are you using?
If you're using a relatively recent version of parted,
then the fact that you're seeing that diagnostic means
that device has a PC98 partition table (or at least that
parted detects it as such -- which may be a bug in parted).
If you're not using parted-2.2 or 2.3,
I suggest you upgrade and try again.
If you are using one of those, please make a copy of
the first few sectors of your disk and send them to this list.
I.e., you could run this and then attach the file F:
dd if=/dev/sdc count=34 > F
