How to correct RAID without reformat

I have a Dell Precision 470. several years old, has worked well. the user thought his hard drive was filling up. as it turns out, it is allocated wrong. (by a previous network admin, of course) but anyway i want to set it up for optimal performance as a RAID 0.

current configuration is: C 19.1 GB NTFS
                                       D  39 MB FAT
                                       129.87   GB Unallocated

It should be  C drive 80 GB set up with RAID 0 for performance. How can I get it to this configuration without having to reformat the computer and setting it up like a new machine?

I did attempt using Boot IT NG, but when the computer booted from the CD, the mouse and keyboard no longer worked and I had no way of working with the disks.

Install the RAID driver, and then back up both drives to separate media (if you are going to reuse the D drive). Configure the hardware to operate as a RAID 0 array (you didn't say what drives you were going to use for this), restore the C drive to the RAID 0 array, and restore the D drive to wherever you want it, if you needed to use the old D drive (you can skip this step if you didn't touch it). You will need to set up your BIOS to boot from the RAID 0 array. It is important to install the RAID driver before you back up the drive or it will not be bootable when you restore the C drive.

If you only have a single drive, you cannot do this - RAID 0 requires two drives.

Actually RAID 0 can be construed as 1 drive without redundency.
But ,I don't get what you mean by slowing down and need to set up as RAID 0.
Why would you want to do RAID 0  anyway?
If you do lose a drive in a dual drive RAID 0 config,your data is toast!
Not a good idea.

the data is saved on a network drive. the computer is used in an engineering environment where writing to disk needs to be optimized. I have backed up the computer to minimize data loss, although the 'important stuff' is on network drives. the computer has 2 hard drives of 80 GB each. drive C is configured for 20GB. drive D (local) is allocated to 80 GB. the rest is unallocated. from here, how do I set up the RAID 0 and configure C to 80 GB? do I reformat the whole computer disks and all? Is it possible to get the raid going without doing this? I tried starting setting up the raid from the bios without reformatting but i got errors, which i expected. I tried to reallocate the drive space by using a product called BootIT NG, which i used before with success on another computer (although a smaller hard drive) but when I tried it on this computer, the interface comes up, but then the mouse and keyboard stop working so then i cannot proceed from here. What is the next best step to get raid 0 started? I have downloaded the steps from Dell support but they are a bit too general.

current configuration is:
C 19.1 GB NTFS
D  39 MB FAT                                      
129.87   GB Unallocated        

Looks like it is allready at RAID 0,so it looks like the BootIT NG  has issues with that controller since it works at a BIOS level and not at an OS one..

Does it give you the choice of installing a 3rd party driver when you boot the utility disk?
If not .I would look at another 3rd party partition manager that allows fot that.

Paragon and Partition Magic are two that I would consider.

I think you can get both as demo's just to see if it works.
