disk failure orz

Update2: RAID array was successfully rebuilt! Hurray for RAID 5 (kind of. note to anyone considering RAID 5… don’t be stupid like me and boot off your RAID 5 array. And for reference, though yes, you recovery 100% of your data in the case of a drive failure, it can take a long time to rebuild the array on a new drive… like, in my case… ~32 hours). Now backing everything up, the bulk of which should be done copying when I get home. After that I just need to work on my external backup while I reinstall programs and get to work on my next post :P
Update: After suffering through a supposedly failed raid, installing windows on a new hard drive, and bring all my old drives back online… i’m actually in the process of restoring my raid. Will take a long time, but if all goes well, I should be back on track in the next day or two. (i.e. have that senhime review up :P)
I had been hoping to post my senhime review last night, but instead was greeted with a failed disk. This is, sadly, not an April Fools’ joke.
Technically I should be able to recover everything… but that’s only if I can rebuild my raid -_-
If any tech saavy peeps are out there, let me know if you have any suggestions (details under the cut)
So I’m currently running on an ASUS maximus extreme, and had been using the built in Intel Matrix RAID stuff to make a 4 disk RAID 5 array. This motherboard has the Intel ICH9R southbridge, which I believe contains the RAID controller.
This RAID 5 is sadly the only set of hard disks in my system, so yes, my operating system (vista 64) is being run off the raid too.
At any rate, when I booted up, the motherboard was stuck on the detect IDE step for a long time, and finally, after like a minute, it continued, to where I saw that the RAID was degraded (thankfully not failed). The computer continued to boot after a while… and to my knowledge is still booting. (it’s at the black screen with the green progress bar) It’s been booting for 12 hours now, but I’m afraid to turn it off and potentially kill the array completely. (there is near constant disk activity)
Anyone out there running a raid 5 on the intel ich9r? Is this normal for a degraded array? What the hell is it doing?
Barring any further advice, my current plan is:
1.) Wait for the computer to finish booting up
2.) Shut down
3.) Pop in my spare drive (glad I bought one)
4.) Boot up again
5.) Rebuild the RAID using the new drive
I wouldn’t be fretting nearly so much if I could just understand why it’s taking so dang long to boot up. It seems weird that reading from a degraded array would take this much longer… which has me worried it’s doing something else.
Blargh. I’m at work now so I won’t be able to check on things ’till I get home… not sure what I’m going to do if it’s still booting. I’m tenatively planning on getting another pair of hard drives today so I can run my OS on a RAID 1 array and then use the RAID 5 for storage only.
