One of two HDD's not in use in RAID 0?

My question involves a problem concerning two WD 150Gb HDD's in a RAID 0 configuration. I'm unsure if this is a software or hardware problem or ?

Pertinent specs.: Custom built machine, Win. XP Pro Version 2002 Sp3 (installed 32 bit), Abit Crosshair MB (Socket AM2), AMD Athlon 64 x2 6000+ Windsor 3.0Ghz cpu, Mushkin DDR2 800 Ram (4Gb), 2 Western Digital 150Gb Raptor HDD’s, 2 GeForce 8600 GT video cards, Rosewell Extreme Series 850 Watt PS.

This is my third RAID 0 installation, all have functioned well without problems with one "small" exception regarding this latest installation. The OS installation was smooth, the computer boots properly, including the appropriate HDD boot postings of a healthy striping, and the machine functions as expected.

Nvidia MediaShield properly shows both HDD's,

and checking the Device Manager for Disk drives shows a Healthy Nvidia Stripe of the proper size.

However, when I right click Local Disk C in My Computer and check Properties I only see information for one of the HDD’s.

Finally, using Disk Manager to look at the HDD's it may provide clues regarding this discrepancy but I do not know how to interpret the information.

If someone could please tell me what is happening and how I might correct this discrepancy I would be most grateful.

 

I am completing this thread with my solution in case someone else needs the fix.

I still don't know how I caused the problem, but I have resolved the issue using the BootIt™ Next Generation program. I am amazed that the software can resize, move, extend, etc. disk partitions and volumes, even on striped arrays. I was able to use the 30 day trial version to delete the MBR 1 Extended Partition and then to resize the MBR 0 Partition to include the Free Space. Now my RAID 0 array includes all the space on my HDD's. Awesome!

Needless to say I purchased the product. :-D

 

Btw, if anyone knows what I may have done to muxxor the installation/configuration I'd appreciate the insight.
