When I installed Windows 7 on this computer, I saw Intel Rapid Storage Technology on it, and I created a Volume of the two drives in this computer thinking that this would like combine the size of the two drives into one pseudodrive. But that didn't happen, it doesn't seem to have done anything at all and now my second drive is gone. Is there a way to undo the Volumes and Arrays in Intel Rapid Storage Technology?
What KIND of volume did you make (this is the very first thing it asks you, as I recall)? There are multiple kinds of RAID arrays available - it sounds like you made a RAID1 array, which is for redundancy, when you meant to make a RAID0 array, which is for increased capacity/speed.
You should be able to select the array and change the type (or disable entirely) from the RST interface.
EDIT: If this is the current active system volume (i.e., Windows is installed on it) there's no way to easily disable a RAID0 this after the fact. You'll need to change it from the RAID BIOS (usually Ctrl+I as the system is booting up for Intel controllers), but this will completely wipe the contents of the drives. You need to either clone the installation off to a third drive, and then clone it back on, or just format and start from scratch.
