Raid problems..

I can't explain the problem very well but I will try to tell every detail I know.

==System and configuration==
Motherboard: ASUS P5K Pro
Setup: RAID 5
HDD's: Three HDD's with Windows XP installed

What caused the problem: Power failure

What the situation is: Windows does not boot, says the following:


I don't know where to start actually, all I want is to restore the data. I've attached a 4th HDD to install Windows and rebuild the RAID setup somehow.

Intel Storage Manager says the RAID 5 setup has to be rebuild ("Volumes with 'Rebuild' status will be rebuilt within the operating system"), which will hapen within Windows, but there is no way we're able to get Windows going again*.

To be honest, I'm quite a noob when we start talking about RAID .. all I want is to restore the data. If you reply, please use clear instructions which are easy to understand :-)

* When booting in safe mode it hangs on "system.log"

Thanks!

I tried to get the installation running but I'm having a 0x7b BSOD constantly, I used no RAID drivers, I used the RAID drivers from the ASUS website.. all without a result.

I also tried HBCD 10 Mini XP, and I get the error "iaStor.sys is corrupted", which I've also seen when trying to install Windows XP.

***If you don't already have a backup, you should make one before you attempt to rebuild...if the volume is recognized, create an image from that - free tools are available on UBCD (www.ultimatebootcd.com).  Another great tool is RAID Reconstructor, which will allow you to make an image of a failed volume and recover data (www.runtime.org)***
The iaStor.sys error is known and has been corrected...you need the latest driver.

Since you were using RAID 5, you should still be able to boot to your OS.  Since you have an error, it could be using corrupted data.  Did you happen to have write caching enabled?  When you boot, enter the intel matrix storage manager option rom (i think ctrl+i)...you may have to force it back online.  Do you know which drive was marked as failed?  
Try to get the volume to boot...if you can't, proceed with your installation of windows on another hdd.  Instead of using the intel controller, install on the marvell ports and keep in ide emulation mode (non-enhanced) - this should allow for a quick and easy install.  Ensure the new drive is listed before the array in your boot order....you may want to just disconnect the 3 array hdd's to limit complications.   After you install Windows, reinstall the array hdds and ensure the intel controller is raid enabled and the option rom is on.  You may need to reboot once for it to pick up the array, at which point you can modify your boot order to keep the single drive on top.  Boot to windows, install the latest version of the intel matrix storage manager.
At this point you should be able to detect your array and get some further information.  Report back with status before you start to rebuild.

There should be a pre-OS load key combination that will bring you to the BIOS-managed RAID array, allowing you to rebuild the array prior to booting WIndows
