Hi
I recently partitioned my 500gb hdd to four drives c,e,f,h.each 100gb. When I accessed the partitions using disk manager, I found that the remaining 100gb was labelled unallocated space and there was nothing I could do with it i.e activate it, format or partition it. How can I utilize this space? Please help.

:confused:

Read Wikipedia: Disk partitioning or the "Partitions: Basic disks and volumes" section of the Disk Management Help for info regarding the four primary partition limit and extended partitions.
