Our server has an OS RAID 1 and a separate 8 disk RAID 1 array. It was originally running server 2008, but it crashed on us. I attempted to fix the issue by removing the server from the domain, but when I tried to get back in, the local Administrator password didn't work, so I was unable to ever log back into windows.

Basically, I was forced to reinstall windows, so we installed server 2012. The installation went fine. The problem is that the 8-disk array is visible, but it is inaccessible due to permissions (or so it says). However, when I try to forcibly overwrite the permissions on the disk, it says I cannot take control of the disk because I don't have read permissions on the drive. So now we have almost 3 TB of data that is totally inaccessible. How can I reset permissions on the disk? I'm at a total loss here.

This question came from our site for computer enthusiasts and power users.

Eight disk...RAID 1? What? – tombull89 Jul 12 '13 at 8:09
Actually, I've done 4 and 6 disk RAID 1 with mdadm, it's really just a bigger mirror. I've only done it when the disk's been partitioned so /boot is R1, / is R5, /cache is R0, where you've got partitions, and differing raid levels on those. – Tom O'Connor Jul 12 '13 at 8:26
This seems like an odd question to migrate - old and possibly abandoned. – RobM Jul 12 '13 at 9:00

enter image description hereTaking ownership of the drive via drive properties/security/advanced might be a fair place to start before attempting to apply permissions. (I'm assuming that the physical disk & volume has been checked in disk manager and no issues shown there).
