HI guys, I currently have a server running windows server 2008 R2 with IMSM 8.9.0.1023. I recently booted up the system and it has told me that my data volume has failed even though it is configured as a raid10 with one drive out of the four giving me an error. Do you have any idea as to what might be going on? I know that the volume should not have failed since only one drive has gone down.

Are you sure it's raid 10, or could it be raid 0? That's the only way I can see 1 drive causing the raid to fail.

The most common cause in this situation is that another drive is also unstable.

If you don't have a backup, your best bet is to image all of these drives then attempt to manually reconstruct from 2 of the drives. If you're not comfortable doing this, then you'll need a professional lab.

Thanks, Sorry if this might be a stupid question but how would i go about manually reconstructing the drives?

There is commercially available software out there like RAID Reconstructor that you can use to analyze and rebuild a broken RAID volume from images.

The idea in this case is if you have the right 2 drives in tact physically in a RAID 10, you can reconstruct the RAID even if they weren't part of the same RAID 0 set.

The point is that you will want to make images first in case you make a mistake trying to reconstruct, because this is NOT beginner software.
