RAID 5 recovery

March 7, 2009 at 23:56:42
Specs: Windows Vista Ultimate x64
I have a RAID 5 setup with 5 drives using the Intel ICH10R chipset. When I flashed my BIOS recently, it reset its settings to their defaults. When it restarted, it rebooted into Windows before I could change the BIOS settings back to the proper RAID configuration. After setting the BIOS settings back to RAID and rebooting, the RAID array failed. One of the drives was detected as a non-RAID drive. The partition for the RAID volume was inaccessible and Windows Disk Management detected it as type RAW. How can I repair my RAID array? Thank you for your help.

You probably need to find a web site devoted to raid help. Most of the knowledgeable people here do not approve of using raid.

What do you mean by "do not approve of using raid?" How else do you go about creating a 6TB volume?

If you just have to have a 6TB volume, by all means use raid.
I don't think many people here would approve of creating 6TB volumes either. :-)

Again, I guess I don't understand what you mean by not approving. If that's what my computing task requires, that's the computing solution. It doesn't require any sort of approval or disapproval from anyone. I came here seeking help, not approval.

Good luck Jeff! With your attitude, you are probably going to need it. :-)

Some support forum this is. To sum up your responses: 1) everyone here disapproves of you're method. 2) everyone here disapproves of you're task. 3) you're the one with an attitude.

You might want to check yourself dude. I certainly hope you don't speak for all the experts on this forum. You're not much of a spokesperson.

What I was trying to get across to you jeff, was that myself and most of the helpers on this forum do not use Raid, and probably have no idea how to recover from a Raid 5 corruption.

Here's the best help I can give. ;-)

@1stepbeyond: Thank you for the link.

@aegis1: It'd be smart to not assume people that post on the forum are guaranteed fools. Of course I searched google extensively before I even thought about posting here. Your responses give you absolutely zero credibility and only make yourself look like a fool. If you don't know anything about a problem, then how about you just refrain from responding to it? Speaking for members of the forum as a whole only detracts from the forum's general credibility as well.

Thanks for the feedback, Jeff.
Thanks for the compliment, but I have to admit that I do not speak for members of the forum as a whole? I am very happy that you received the help that you so badly needed, and I'm sorry that my assistance was not up to your expectations. ;-)

hi

i had a little time yesterday, also there was an issue with c.net and a my antivirus kicking me off here , i believe thats been fixed,

anyway the upshot is is probable youve lost your data
i spoke to someone who uses raid5+1 and asks is there a rebuild option in your bios or software?
if not theres a link to a a site here which may help , ive read a lot there but not so certain if it will be successful for you

http://www.runtime.org/raid.htm

as the man said raid 5+1 (mirror) is the only way to go with raid
and he backs up to paid online storage as an extra precaution.

@1stepbeyond: Thanks for the info. I wish there was a rebuild option in my RAID BIOS. That would make this problem much more solvable! Intel should really look into adding this.

But I was able to find a solution! If anyone's interested. This thread traces the steps I went through to fix my problem: http://www.techsupportforum.com/har...

jeff, your link is dead. BTW, copying an address from your browser and pasting in your thread will automatically make it a link.

You were lucky you were able to rebuild the array. From reading about RAID 5 if you lose more than one disk there is no recovery.

Something more for you to think about is this. If you go to Seagate, WD, etc and read about their offerings you will find that consumer grade drives are prone to fall out of an array even if they have not actually failed. A simple self check is enough to trigger that. If you are running consumer grade disks and have had no problems in the past, consider yourself fortunate.

With drive pricing constantly falling you may want to consider some sort of backup. I don't have anywhere near that much data but I tend to backup my music and photos on DVDR as I accumulate the files. It isn't so overwhelming then.

Yeah, a backup is always nice to have in these sorts of situations. Maybe when blu-ray media comes down in price. But as it is right now at no less than $4.50 a pop, which gets you 25GB, it'd cost me almost twice as much as it would cost to buy the equivalent amount of space in hard drives. DVD media isn't much better as it would be a lot slower to backup to. I'd have to burn hundreds of them. It'd cost about half as much as the equivalent hard drive space in the end though.

Thing about DVDR is that once you burn them you don't need to worry about it anymore except if they get lost. Depends on what you are backing up.

I can't imagine ever having 3.2TB of data. I am running about 400GB right now. I do have old stuff archived on CDR & DVDR.

You must keep every file you ever made.
