Primary Partition

Hi,

I was reading Windows2000 Server installation Guide by Dell. They recommend that we should create 2 partitions on the physical disk. Primary partition of 4095Mb and partition the rest of the disk space for data or application. In the past,I usually create one partition when installing Windows2000 Server. The reason being is to avoid having C-drive running out of space at later stage. Could somebody tell me what are the advantages of having 2 partitions as oppose to just one?

Look forward to hearing from you.

Regards,
Edmond
