You seem to have vestigial signatures of other filesystems on the two
partitions. You can use "wipefs" to list all filesystem signatures on a
partition and also to remove the outdated one. (See the manpage and be
careful not too delete the signature of the current ext3 filesystem.)
As soon as there is only one signature left on each of the partitions,
blkid and all the rest should work again.
Two other important tests are:
findfs LABEL=hdb1
findfs UUID=03c23684-dea8-458d-b04b-0ae8a056cb0d
Both these commands should return "/dev/sdc1".
