Partition created in Windows didn't show on Mac OS

[forky]

I used bootcamp to create a partition for installing Windows.
Everything worked fine and I still see the Windows partition on Mac OS.
But when I used Disk Management on the Windows and split its partition to 2 new partitions (C: and D: on Windows), they didn't show up on the Mac OS. The Mac OS still showed the Windows partition as one (which is created by bootcamp), not two.

Any solution?

I'm using Vista Ultimate with and Mac OS X 10.5.2.

That's probably normal. I recommend deleting that partition, though. For one, if you do any disk utility work on it, and it'll probably see it as a corrupt sector.

I would boot into OS X, download/purchase iPartition (http://www.coriolis-systems.com/iPartition.php) and use it to partition the drive for you.
