If you run fdisk /dev/hdc, you can change the partition types.
At the fdisk prompt, a "p" will list the partition table.
 From there you use "t" to change a partition type.
Ext2/3 partitions are type 83 and linux swap is type 82.
Make sure you only change the partitions that you wanted to be ext3, and not 
your windows partitions.
A "w" will write the new table and exit, and a "q" exits without writing if 
you make a mistake.
A "m" gives a list of choices (menu).
