So I reset my BIOS to Defaults, rebooted, then was reminded to turn on the RAID/AHCI option. Set it, then rebooted but this time when listing the volumes it says it has a status of "Failed".

When I enter the Raid setup util, and in the report below the volume, the first drive in the array is listed as Non-RAID.

Is there a way to just re-add the disk and carry on my merry way?

Or do I need to wipe, rebuild, then restore from backup? On the upside, I do have recent backups.

I think you have to rebuild, but I'm not really sure.

Good thing you backup your data.

EDIT: Just heard the good news on Twitter. Glad to see that you have it back up again!

If you've corrupted the raid, you need to reformat. sorry but that's the way the cookie crumbles. sorry for your loss

yeah you have to rebuild your raid array and you will lose your data, its good to always backup so if there is a problem like this you can always restore things.

And this is why raid 0 is a bad idea.

This goes without saying but
1. If you can't afford to lose it don't mod or OC it.
2. At least read the OP before commenting.

This happened often on my old DFI, but powering it completely off and then turning it back on fixed it.

You've probably already tried this, though.

RAID 0 is not a "bad idea", you just have to understand what RAID 0 is, how it works, and why you want to use it. I have a short stroked RAID 0 array that is noticeably faster than any single drive I've used. RAID 0 is generally used to increase throughput.

Since you effectively double your chances for drive failure though, since one drive dropping means the whole array is gone, you should also not keep ANY data on the volume except for your OS, Apps, etc.

I redirect my documents folder onto a separate drive, keep all my downloads etc on a seperate drive, that way if my array fails I only need to reinstall Windows and my apps to be right back where I was.

Eventually I'll setup a second RAID 1 2tb volume for my data so it is even more secure.

I wouldn't trade in my RAID 0 for anything, except perhaps one of Intel's SSD drives.

Also, for the OP, you need to rebuild your array.

If you end up losing your data acronis makes a program that will see and work with RAID arrays. Google it.

Good news! I booted into ubuntu live cd, installed dmraid, looked at it with gparted and fdisk, rebooted, and magically it booted into windows. I think the controller was just confused. Or it just needed to be kicked around for a few reboots.

Either way, raid 0 isn't a bad idea -- that's why i have full and incremental backups.

I'll probably end up getting another 1 or 2 drives and going raid-5 or raid-10 in the future.

Glad you got it sorted. Mine has done that a few times but either power cycling my PC or rebooting a few times fixed it.

I use raid0 for speed, and an external USB drive for my important storage I should probably start backing up my external since those are subjected to quite a bit of heat..

Well now it's back and seems to 'fail' after every couple reboots.

I'm thinking just to be safe, to move my installation off the RAID volume and run single disk.
