Hey Folks.  

I basically have a failed Raid 5 configured w/ Dynamic Disks.  We have a server running Windows 2003 Server w/ (8) 250GB SATA Hard Drives.

Here is the configuration:
Volume 1 (Mirror) -40GB On Disk 1 and Disk 2 for OS
Volume 2 (Raid 5) - 210GB on Disk 1 / 2 / 3 / 4 / 5 / 6 / 7 / 8

What Happened.
Drive 4 Failed on the server, so Raid 5 Volume was inaccesible.  Powered down the server and checked and reseated drive 4 to see if it will come back online (These are removable / hot swap bays).

On restart, Drive 4 was still dead, and now Drive 3 went Missing in Disk Management.

Powered down unit again, and reseated Disk 3.

Turn server back on, and Raid 5 is still Failed, but disk management shows the following items:
2 Missing Disks and 1 Foreign Disks.

From what I see, the missing drives are both disk 3 and 4.  DIsk 3 is plugged in, but does not show as part of the array, but as a foreign drive.

I attempted to Import the foreign drive, it tell me that it is part of a RAID5, but it does not import.

Is there anyway I can reattached the Foreign Disk 3 back to my Raid 5?  WIthout that Disk 3, I can not recover the data.

Any help or suggestions would greatly be appreciated.

Ok..  I am trying to rebuild a Virtual Raid 5.  I am using R-Studio, but ahving no luck.

What I am doing is bascially setting the 6 drives + 1 foreign drives as a Raid 5 (w/ one missing disk).  There is no reason for me to believe foreign disk is physically bad or corrupted.  It just seems window doesn't want to let it back into the array to give me a workign Volume.

I am hoping that a Virtual Raid 5 will work.  Seems there is a kink in R-Studio.  I have used it in the past for other Raid and it works great.  Just a little buggy right now in the Virtual Raid 5.  Anyone have any other program to suggest?

Used RStudio to build a virtual raid to incporate the Foreign Disk to the array.  Was able to recover the data that way.  I restored 1TB of data and files.  No need to go to backups.  Issue closed
