I'm working with a Dell PowerEdge R750xs that was previously set up with a 45TB RAID array, including a 1TB "Exports" drive and a 44TB video storage drive, through a 3xLogic VIGIL NVR on Windows Server 2022. Things went south with the NVR database, so we decided to fresh install Windows. Initially, the other tech installed Windows Server 2019, but we faced driver issues, especially with the RAID card, which is essential for accessing the storage media. Afterward, he installed Windows Server 2022, but it just got stuck on the loading screen. As a last resort, we tried Windows 11, which actually booted, but when selecting the installation drive, the 44TB volume showed as unallocated. Even after installation, the drive still remains unallocated in the system. Attempting to use DISKPART hasn't shown any sign of the lost partition either. I'm really concerned since it contains the last four months' worth of video storage. What can I do to recover it?

To start, could you clarify the RAID setup? What type of RAID card are you using? Knowing whether you're on RAID 5, 6, etc., can help. A common choice would be the PERC H755 RAID controller, but we need specifics to help out further.
I believe it's RAID6, but I’ll confirm that. The RAID card is a PERC H755. The "Exports" volume is still showing up, which seems to indicate the array is intact.
