I have about 5 or 6 disk connected to my Server 2012. In Disk managment i had raided some of my HD's.  I had physicaly moved some of my drives in the server and added a drive. Now the disk dosen't show up. I tried to reactive the volume but it keeps telling me the volume is offline. I dont remeber how i had the drives connected and in what order. I do not want to lose my data. Any help would be apprciated!

If you can't remember which order the drives were connected in and you can't risk loosing data. Pull the drives and send them for data recovery. Typically If the drives are not connected in their original configuration when the raid 5 was created the raid will fail. And your volumes will be unavailable..

Data recovery assumes no backups.  Being a server and a responsible admin there are backups.

 

You need to remove the added drive and put the drives back exactly as they were before. Then you can mark the drives so you know what is what before you add the new drive.

 

Seeing raid 5 and spanned disks is not comforting.  Spanning has no fault tolerance in case of drive failure.  Always make sure your backups are tested so you know they are good.

Putting the drives back in exactly as they were before is going to be a shell game at best. 

 

 I do not want to lose my data. 

 

If he had backups, He wouldn't be concerned with loosing data.

Good deductions. Everyone has to learn at least one memorable lesson the hard way.
