Wrong fs type detected

I have a external firewire drive formatted as ext3 under RH7.2.  When I 
plug it in to my new FC4 machine it complains with the following:

FAT: Did not find valid FSINFO signature.
     Found signature1 0x00000000 signature2 0x00000000 (sector = 1)
FAT: Filesystem panic (dev sdb1)
    invalid access to FAT (entry 0x00c0000f)
    File system has been set read-only

I have to manually mount it as ext3 and everything is fine.  I have two 
other external firewire drives one formatted FAT32 and the other ext3 
both of these are recognized correctly and automatically mounted.  
Here's the output from fdisk for the drive that isn't recognized:

Disk /dev/sdc: 203.9 GB, 203927060480 bytes
255 heads, 63 sectors/track, 24792 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

   Device Boot      Start         End      Blocks   Id  System
/dev/sdc1               1       24792   199141708+  83  Linux

Any ideas??
