A Curious RAID problem

Wonder if anyone can shed some light on my problem

I am running a MSI K9A2 CF, Athlon X2, 4GB Ram, using the RAID mode with 2 identical Hitachi drives in RAID 0. In addition I have a second drive (another Hitachi) running in JBOD

Its all running fine under Windows XP Pro I have even got a Slipstreamed CD with the RAID drivers on it which I have once before reinstalled from.

However today I attempted to install the Win 7 RC and my RAID controller did not show up in the options. According to MSI it should so I tried all the obvious things and still nothing. I therefore like a brave explorer.... gave up and thought oh well XP again it is so I put in my trusty disk rebooted and went to install XP and ... no RAID Arrays again. Now I know they exist and I know they work because I'm using it right now.

Can anyone cast any light on my problem?

Ok essentially I desided to move to Win 7 RC my XP install was getting a bit grindy so I figured Id reinstall it anyways.

I ran up the Win 7 Installer (by rebooting off the DVD) and none of the RAID Arrays showed on the options for install. I figured no drivers but the MoBo manufacturer said there were in the install.

At this point I decided to give up. I have always been able to reboot into XP (the grindy one) so obviously the RAID still works its just not showing on the install options

So I decided to give up on Win 7 and decided to reinstall XP instead. However the RAID Arrays were not showing in the install options for XP either (I was using a slipstreamed disk with the drivers for the RAID. A disk I have used on this system so I know it works) So still no sign of the RAID Arrays.

So now Im wondering how I am able to boot off a drive that no windows install acknowledges the existance of.

FYI I tried putting the SATA controller in IDE mode and it showed the drives in the install options. I then put it back to RAID mode and nothing again.

I understand your point about drivers however as I stated I have a slipstream XP disk with my RAID drivers on. I have used it before and it worked just fine. Now it does not work.

I do not need the Data on the RAID.

I have already tried downloading the drivers MSI swears are in Windows 7 independantly and tried them on a USB drive, apparently they are not new news to Windows 7.

I am convinced it is not a straightfoward driver issue for these reasons.

During the BIOS boot the RAID controller initializes and acknowledges the RAID 0 and the JBOD disk as functional. I am using the RAID controller on the K9A2 CF motherboard. When I tried to install Windows 7 it only found the IDE drive and the DVD drive which I have in my system.

No chance I did anything wrong with the drivers as the disk had worked on this very machine with exactly this config before. I have already broken and recreated the RAID to no avail

Thank you for trying. Anyone else got any ideas ?

Ok in Windows 7 turned out after some messing about it was a driver problem which made me feel foolish that'll teach me to believe MSI. Does not solve my XP issue however still don't understand how a working slipstream driver disk did work and now doesn't but guess I won't let it bother me. Thanks for all your help guys. Problem solved.
