AWOL partition

[Leright]

I have the 250 gig WD 16 meg cache drive. I was having trouble with a partition (data partition aside from windows partition). I deleted the partition thinking it would become unallocated space, but the space just completely disappeared. I tried the recovery console aprtition utility and that didn't find the space either. I even tried deleting my primary partition hoping that would bring back the missing space but no luck.

Any ideas?
