extending primary disk partition

[Philip55]

my acer 5943 notebook came with the disk in 2 partitions, but as i was filling up the primary partition of the c drive fairly fast with video etc, I thought I could extend the drive to capture the free space.

However the extend volume option is not available(maybe because it is a 'striped' drive).

is it possible to extend the drive,if possible without having to delete all existing stuff on the primary drive? thanks

I attach a screen shot.
