Recently had a RAID 5 failure(one critical drive and one failed drive) requiring recreation of the RAID 5(12T) using "save old data"...  after 5 days the RAID was recovered (all original drives were recovered, sectors repaired, etc.) and appears 'normal'.  I can see the RAID 5 disk in the win manager; however, WIN 7 64 wants to initialize this disk...  If I do this I assume I will lose all access to the 'old' files... 

So, how can I recover the GUID or re-create it without losing access to my data?  Where is the GUID located?  I have a saved system backup prior to the RAID rebuild if that helps...

Thanks ahead...  J
