I had a similar problem before but I don't remember what exactly was the issue. So if the window server crashed on a hardware raid 5, is it possible to repair? For example, with desktop pc (with single hard drive) when the windows crashed, I was always able to put in the windows xp cd and run the windows repair. Just wondering if I can also do this on hardware raid, if so, what's the procedure?

Treat the problem as if there was no RAID controller.  With a degraded RAID5, i.e, one disk missing then it runs slower but it stays online.  The O/S doesn't technically know you have a single disk, a healthy RAID5 or a degraded RAID5.   Take the RAID out of the equation.

However, there is an exception.  If you have a low-end RAID, i.e, a "fakeraid" controller where the work is actually done with device drivers and your controller is a $2.00 chip on the motherboard, then all bets are off, and you should read the documentation and check with the manufacturer for procedure.

But easy way to find out ... boot the recovery CD and see if it "sees" the C drive and your files, or if it complains about missing a driver.

Thank you! great point. But I don't understand what you mean about the low-end raid...
>>where the work is actually done with device drivers.....

The high end raid also needs me to load driver when installing windows or by using the HP smart CD....

>>boot the recovery CD and see if it "sees" the C drive and your files, or if it complains about missing a driver

Not sure what you mean here.... if I try to run the repair, I don't think there is an option to see the files, it just shows the os and ask me if I want to repair it... I remember if I didn't load the raid driver in the beginning, it will say something like disk not found....
