Update: This problem fixed itself after my RAID 10 was allowed to finish rebuilding. The problem was listed as a known issue of the 9.6.0.1014 Intel RAID drivers - it might be fixed in newer versions of the driver, but it hasn't been listed as resolved in any release notes yet that I have been able to see.

---

I have a very bizarre situation with my Intel RAID. I normally have 4 identical 1.5TB drives in Matrix RAID, creating a 2TB RAID 10 and a 1.6 TB RAID 0. My computer recently BSOD'd and one of the drives dropped out. When I restarted, I noticed that my RAID 0 volume was gone. Windows was detecting a new drive, and the Intel app was complaining about a missing drive. I shut down, made sure the "missing" drive was still connected, started it up, and went to the configuration manager. It asked for the drive to rebuild to, so I selected the drive that dropped out. (This isn't what normally happens when a drive drops out - I can usually just tell the Intel application to mark the dropped drive as "Normal".)

Strangely enough, the system now thinks there are two different drives with almost the same serial number - one that is connected, and one that is missing. The real drive is now being used for the RAID 10, but it's not being recognized as the same drive as the one that was being used for the RAID 0. So now this Matrix RAID array and all its volumes appear as having 5 "drives", the four real drives and a "ghost".

I'm not sure how to proceed from here - I don't think I have anything valuable on the RAID 0 volume, but I don't want to delete it and remake it if it won't solve the problem.

I have a version of the Intel Rapid Storage Tech program that doesn't let me copy and paste, but the bits that I figure are most relevant are:

I just found a document describing what might be this as a "Known issue" under 9.6.0.1014. The latest (10.1.0.1008) doesn't list it as either known or resolved.

http://downloadmirror.intel.com/18667/eng/ReleaseNotes1...

3005666
:0 or colon + zero is appended to serial number of drive in recovery volume

I'll probably try upgrading to 10.1.0.1008 after it finishes rebuilding if I don't find anything else to do.

==

[EDIT] Wow, and now it just magically fixed itself after the rebuild finished. Panicked for no reason, I guess? :)  Now I can just mark the drive as "Normal", like a typical dropped drive.

Going to update drivers anyway, so it (hopefully) doesn't happen again. I'll leave the info here for any future poor people that this happens to.

I haven't seen the problem for a while, and I always have had to just wait. Is a volume still rebuilding? If so, you probably just need to wait (or tell the utility to rebuild to the disk, if possible).

My both drives are having issue in Raid 5, so i cant rebuild but if somehow if ichange Raid information in 1st disk by removing serial number extracharacter(:0) or change my actual HDD serial to serial:0 my raid can be rebuild.
Is there any way.
