See this article, surprisingly this guy is doing exactly what you want to do, with the same exact hardware and software.


Good luck and hope this help you out,

Check the manual of your RAID controller, many HP smartarray controllers offer the possibility to add disks to existing arrays on the fly, and how that is done, and what precautions you should take are explained in there. Also, before you start make sure your backups are 100% OK in case anything goes wrong.

After the array has been expanded, you'll need a 3rd party partition manipulation utility if you want to increase the size of C:, or move D: away from C: so you get the space needed to increase the size of C:. A free tool that usually works fine with most RAID controllers is the Partition Editor (GParted) on the PartedMagic LiveCD:
