Disk Partition Overflow

I have several NT systems that have a single disk that is partioned into 4 logical drives. The 1st drive is 2008 MB, the second, 1469 MB, the third 1469 MB, and the forth 1181 MB.

I understand that NT has some sort of bug that only allows for 2 GB partitions. My question is How do I make the logical drives overflow to one another when one gets full? Right now I just monitor C drive and try to start moving things when it starts to fill-up. Or load programs onto D drive. Surely there is a way to do this automatically?
