Looking for a way to Convert RAID to non-RAID

Hi...

I setup my storage with Intel Rapid Storage and messed it up, as I lack any knowledge of it.

Lenovo U310, it came with a 30GB SSD and 500GB HDD.

I deleted everything on it and installed Windows 8 on the SSD and used the 500GB HDD as main storage. It was a rather good setup until I installed Intel Rapid Storage and accidentally added my HDD to RAID. Now I can't access the partition on my HDD, it had important data on it. I can try and recover the lost data but no software can detect my HDD, it only shows up as a RAID array.

I can reinstall the whole OS, but all I need is access to the partitions on the HDD.
testdisk can do that once I get diskmgmt.msc or any good Partition tool to detect the HDD.

Any help in this regard is appreciated.

I've attached the Intel Rapid Storage screenshot and the system report of it.

Sorry to say it but, "It was a rather good setup until I installed Intel Rapid Storage and accidentally added my HDD to RAID".
Usually it will prompt you saying that all data will be lost when performing this action.
As well the drives need to be the same size or greater to create the array.
So the 500GB would normally be downsized to a 30GB drive in the Raid 0 configuration in order to synchronize, which you can see it has done in the Volume_0000, Type: Raid 0, 30 GB in the image you uploaded.

It is more than likely that the data that was on the drives is now corrupted and will not be recoverable. Even more so since Raid 0 (striping) was used. Striping (Raid 0) spans the data across 2 drives, meaning the data is no longer "whole". Some will be on one drive, the rest on the other.
This means instead of having a 30GB Drive and a 500GB Drive, you have combined both drives to act as a single 30GB drive.
Best bet to recover would be to see if you can't mount and read the raid drive in a LiveCD/PE Boot disk environment, and copy the data to a different non-raid drive, such as an external backup drive. Afterward destroy the raid array, reinstall windows, and migrate your data back to the original drive.

Another option is that you can attempt to remove the drive from the array, and you should get the same prompt saying that data will be lost, using a LiveCD or PE Boot disk. Then see if it will boot in IDE/AHCI mode. But more than certain anything that was on either drive is jumbled up and can't be recovered this way.
