Has anyone else seen this before? It don't make sense unless it was installed motherboard older than 2002 or 2003.

Depends on how it was partitioned - I highly doubt the Vista install was used to do the partitioning, given the fact that this is new hardware. It's more likely a 3rd party tool (or the hard drive vendor shipped it partitioned this way), and the user just chose the C: drive already partitioned to install to during Vista setup.

Best bet is to boot from the Vista DVD, delete the partitions from the setup, and then just choose the resulting 500GB empty space to do the install. Vista will partition and format the empty 500GB properly.

This appears to be with a newly purchased HDD.

It don't matter if the HDD is new or old. What cluberti is trying to say is, the HDD was partitioned with a tool that doesn't support large HDD's. Thus, the remaining space is unallocated.

All he needs to do is install Vista and use Vista's partition manager to delete all partitions that recreate them.

Or, if he doesn't want to reinstall, he can create new partitions in the unallocated space in disk management. But, in my opinion, it's a pretty big partition for Vista.
