No conclusion. Ran fdisk, went to advanced menu and chose "fix partition table
order". The "print" of this shows what I described. The reason would be:
hdc1 is now an EXTENDED partion.
hdc2 linux ext3 is a primary partion
hdc3 swap is also.
All the logical partitions (within hdc1) follow.

Knoppix is around just for such things.
