Raid 5 Rebuild Help

post #1 of 4
Thread Starter 
I'll get the details out of the way first:
Windows XP
RocketRaid 454 4x250GB WD2500JB HDD's in RAID5

Okay, I turned on my computer this morrning and I heard the tell tale clicking sound of a failing HDD. When I booted my computer said my Raid5 had failed (because of the failing disk) and needed to be repaired. So I ran to the local store, bought a new (matching) HDD, isolated the failed drive and replaced it. A few seconds later I was rebuilding my array and everything was fine.

Flash forward 2 hours, and im 30% done the rebuild when... the power goes out!!!

Once power is back I try to start the rebuild again only now my computer doesn't find 1 failed raid 5 its find 2! (I only have one) It says disk 1 and 4 are in a failed 750GB raid5 and disk 3 is in a seperate 750GB raid5. I only have 1 750GB raid5!

How can I get the raid card to notice that the 3 drives all belong to the SAME Raid5 not 2 different ones? Thanks in advance.

The fact that the power went out in the middle of the rebuild might mean something is now seriously screwed up.

My recommendation is to REFORMAT the NEW drive (The one that got screwed up when rebuilding due to the power outage), and try again.

If the power went out when it was writing to the disc, it probably destroyed the data integrity on it.

If it's one of the old drives that is being misrecognized, I'd say you lost your data.

Man I hope thats not the case. It would suck to loose all of your data (expecialy since you were using 750 gigers) and even running RAID 5... Good luck, and with all that precious data, you might want to look into a power backup.
