Un-Hiding Hidden Partition

Hi everyone,
On a recent Dell I purchased, I opted to have all original software pre-installed on a separate partition as opposed to having a reinstall CD. The only thing I didn’t foresee was that the separate partition would be hidden. I can’t access the 4GB or so of original Dell Software via Windows unless I choose a restore option during a clean format.

Does anybody know of any programs, preferably free, that would allow me to unhide the partition? Almost all of the threads here recommended that one use Partition Magic, so will their Free Trial allow me to unhide the partition?

Thanks!
Kirupa =)
