What's happening? I have a Windows 2003 server workikng flawlessly on software RAID 0. I've noticed recently that one of my drive indicates "error" in the drive management. So I decided to unplug on of the drive to locate which one is in trouble. Since I'm in mirror (RAID 0), it should start normally. No, it didn't turned that well. It will boot to the Windows Server 2003 logo for about 10-15 seconds and then, the infamous blue screen of death... The meesge is :
A problem has been detected and Windows has been shut down to prevent damage to your computer... Technical information: STOP 0x0000007B (0x8A093DF8,0xC0000010,0x00000000,0x00000000). Not really helping. I tought that I've simply unplugged the failing disk and replug it back. Same error!! I disconnected the second drive and started and still the same error. All I have done was to unplug one of the drive and reconnect it and now my server don't want to boot anymore. I've tried all the allowed startup options (Last know working configuration, safe mode, debugging, etc) and still, nothing. I am a bit anxious. Can somebody help me (and quickly too, it's our web and mail server)? Giant thanks in advance.

Sorry but RAID 0 is is not mirroring it's spanning
It's used for maximum speed but minimum tolerance. You lost your disk because you effectively removed part of it

My mistake, the RAID is 1 because when I set it up, it was the mirror option. In the drive management, I was able to see 2 "C" drives and the space available was 73 Gigs (my 2 drives are 73 Gigs each). Please, don't scare me like that. :)

Now you've returned from the hell of "What have I done????" ;-)
A quick look here: http://pcsupport.about.com/od/findbyerrormessage/a/stop0x0000007b.htm has useful checks to perform.
Are you able to at least get to a command prompt start up?

I've booted the server using ERD Commander 2005. In the computer management, I can access the disk management console. My Disk 0 is online but no more volume (Unallocated). Disk 1 is healhty and the C: partition appears but his status is offline. Even though, I can access it but it takes about 30 seconds to show the files and does a lot of clunking noises in the process (head noise). OK, that should be the drive I needed to replace but why in the heck I lost the other drive?

Software mirroring is not a good solution as I am pretty sure that the Volume information is only stored on one drive - and unfortunately in this case - on the faulty one.
The stop error alludes to inaccessible boot device which (again unfortunately) would confirm that the boot information (and hence volume info) is only stored on the primary disk which has apparently failed.
You need to look at being able to get the failed disk working at least long enough to boot so you can get the data off the working drive

Hi Kieran. Yeap, you can describe this as the hell of "What have I done????" :) I can't boot from any option of the start menu. It seems like a MBR problem to me.

Well - here's something from left field - it's a hardware issue and one way of getting a disk back for a short while is to freeze it. I know - sound insane, but it does work.
This may help:

you could try plugging the WORKING drive into another Server and it should see it. What seems to have happened is  that the mirror is broken and the Server sees TWO identical drives.

I've unplugged the first drive (the one that I initialy unplugged) and reboot with ERD Commander. Now it won't even see my files. There's nothing. Not even an empty drive. But I still can access another drive (unrelated) on the same SCSI controller. If I reboot with the drive pluged, how can I "force" it to go online?

Yeah, I already save a server by freezing it, I confirm it may work. But in my case, it's not a mechanical problem. Don't forget that all was working fine until I unplugged one drive.

have you tried switch the drives location and seeing if you can boot?

OK. I manage to solve my problem. Here's the solution. Using an other drive on which I have another Windows, I was able to simply boot. In the management console, I was able to see my disk (dynamic). I deleted the volume and then converted it back to Basic. Only that because anything else can write on the disk. Then, Using Acronis Disk Director Server, I was able to use "Recover Partition". The manual settings are recommended and fastier. You might have to set the drive "active". You have to convert it to basic because Acronis DDS don't support dynamic drives. After that, I rebooted and voila! From there, I was able to reconstruct my RAID. My nightmare is gone! :)

Congratulations :-) It's a pity you can't award yourself points, but at least there is another solution listed.
