Need help recovering dynamic disks
Posted: 30 Nov 2015, 17:26
We had 2 SAN disks attached to a Windows Server 2008 server.
Disk 1 - 300 GB
Disk 2 - 600 GB
They were configured as Dynamic. Due to an issue with the SAN, the drives got corrupted. They were coming up on Windows as "Not Initialized".
Microsoft tried several things to fix these but they were not able to.
Disk 1 - 300 GB:
Initially when I ran testdisk on the 300 GB disk, it did not show me any partitions. I changed the cylinders in the disk such that testdisk saw the size of the 300 GB disk as 900 GB. This time testdisk was able to see the partition and the files. I copied the files to a new location, issued the write command and rebooted the server. Now the drive shows up as RAW in disk management and Windows asks me to format it. Seems like the disk has been converted to a basic disk.
Disk 2 - 600 GB:
I have not been able to find any partitions or files on this disk. I have tried adjusting the cylinders such that testdisk sees the disk as 300GB, 600 GB and 900 GB. No luck.
The disks do not necessarily need to be recovered as long as I can recover all the data off of the 600 GB disk as well. Would appreciate any ideas on how to proceed.
