How to rebuild RAID 5 within W7

A few days after initial installation, I had a single drive error with my RAID 5 config. I am running three WD 500GB HDs in a RAID 5, with no other internal drives. I verified the questionable drive with slow scans. I used my Intel BIOS to add the drive back into my RAID. So far everything looked great.

But, my BIOS shows all three drives in a good RAID 5 with a status of "Rebuild." There is also a comment on the BIOS screen that "RAID 5 will be rebuilt within the operating system." I looked in W7 for rebuild opportunities, but I did not finding any. So I assumed that the rebuild would be an automatic/background rebuild. I have had my system on for 1 week with no joy. BIOS status still shows "rebuild."

My question is: Am I OK? The Computer Management shows a single healthy partition at full allocation (1,031GB, with "no" Fault Tolerance)? How do you rebuild a RAID 5 with W7?

No joy... The "Repair" command is not active in Windows 7 DISKPART. "The command you selected is not available with this version of Windows."

It's a little hard to believe that MS has not figured out how to manage RAIDs yet. Time to move back to LINUX... This time for good.

I had the same problem as you, one of my RAID 5 drives check out. Simple enough to replace the drive but then stuck with the rebuild status. My system was still running, but very slow. Funny how MS W7 will build a RAID 5 drive automatically but can't rebuild it. When I saw yours took 44 hrs to defrag/rebuild I contacted MS help to see if there was a better solution. NOT! Considered starting over while I was fretting over "what good is a RAID drive if you can't rebuild it." Glad I decided to defrag. Mine only took 24 hours (12 passes). Started out very slow. Wasn't sure it was working. Took 2 hours to get to 1% of the first pass, then about 8 hours on pass 9. When it completed I restarted and everything checked out and speed back to normal. :)
