I had a Promise RAID with RAID 1.  I added another disk on the same RAID controller to use as another disk.  This worked Ok and I copied a lot of Data across.  At the next rebootthe RAID 1 dissapeared and now shows up in the disk manager and wants to be initialised.

I can not afford to loose this data (windows 2003 server, intell mother board,onboard RAID

How can I get it all going again

Initialising a drive from Disk management just adds a GUID to the drive and associates it with the current windows machine. It does not format it or destroy any info. After initialising you may need to assign a drive letter as well - again not destructive. So long as you don't delete the partition or reformat you should be OK

Scary.  There is a lot of data on this drive that I dont want to loose.  I have backups of critical data but all the other stauffwould be very time consuming to collect

I read in some other posts that initialising the hard drive rewites the MBR and partition table

This is the article fromMS
Not Initialized
The Not Initialized status occurs when a disk does not contain a valid signature. After you install a new disk, Windows XP Professional or the Windows Server 2003 family of operating systems must write a master boot record (MBR) or GUID partition table (GPT) before you can create partitions on the disk. When you first start Disk Management after installing a new disk, a wizard appears that provides a list of the new disks detected. If you cancel the wizard before the disk signature is written, the disk status remains Not Initialized until you right-click the disk and then click Initialize Disk. The disk status briefly changes to Initializing and then Online status.

Initializing the disk leaves you with a raw disk.  Using recovery software I recovered most of the data.  I split the RAID before I did this then I found a partition recovery tool which repaired the initialisation and partition table and I got every thing back
