raid and 0x000000ed

This computer has a Raid configuration.  It would not boot.  Instead, it gave a 0x000000ED error (unmountable_boot_volume). I tried to do a "fixboot", but it said that there were no disks.  The disks were evident in the BIOS.  I tried a re-install and it said the same.  I checked the 3 hard drives and one failed.  I replaced it.  Now the computer flashes a blue screen and restarts on its own.  The RAID configuration is not needed on the computer, so I thought of getting rid of it, but the configuration says that I might lose the data if I do.  Will I?  It is a stripped RAID, with only two of the three Hard Drives.  The third is supposed to be where most of the data is.  How do I keep the data, and get the computer running right?

A striped RAID (RAID-0) will lose ALL the data if ANY of the drives die.  A mirror (RAID-1) has a even number of drives.  If you have three drives, either you have a RAID-0 and lost all your data or you have some other configuration that needs to be determined.

If it was raid 0 array on all 3 disks and 1 hdd failed, the data is gone. You could send the drives to a data recovery firm like gillware or drivesavers but data recovery is expensive.

It has one non-member hard drive.  I am hoping that it is not a part of the configuration.  Can I re-install (I got past that problem) just over the old OS?  Will this keep the data on the non-member intact?

If it was a hot spare, all you need to do is wait for it to rebuild the array, if it is in a degraded state.  The controller should say if it is trying to rebuild the array (you can boot into the controller BIOS to see this).  If it's just a simple boot sector problem, a repair install should preserve your data.
