OK, I'm about to drive down to Mexico and bust this server with a hammer.
Basically, the RAID 5 array is hosed, so we need to copy everything off it so we can rebuild the array. I have everything copied off the drive so far, EXCEPT for the .vhd for the file server. It's a 1TB file, and it as well as everything else is going onto a 3TB external drive.
The specific Robocopy command I'm using is: robocopy /s d:\ e:\MX03-HYPERV-P01 /b /eta /r:0
The exact error I'm getting is: 2016/06/16 17:54:17 ERROR 5 (0x00000005) Copying File d:\MX03-DC2012-P50\Win2K12R2.vhd Access is denied.
Now, I definitely have local admin. I also added myself to the Backup Operators group. I verified I have the backup permission via "whoami /priv". I also added my account explicitly to the folder I'm copying from, as well as the folder I'm copying to, and set it to replace permissions on sub-objects. I also took ownership of both directories (again, setting it on sub-objects).
Nothing's working, and I'm about to lose it. Also, hotfix KB979808 (https://support.microsoft.com/en-us/kb/979808) isn't applicable to this system, I've already tried it.
Now, to be clear, I was able to copy the rest of the vhd's without any issue, other than one. The vhd for the old DC is giving me the same issue, but it died, so I don't care.
Also, the UAC is "off", and I'm running PowerShell as admin. The server is running 2008 R2, and again, I'm copying it to an external HD, specifically a Hitachi drive in a HGST Touro Desk Pro.
Any advice would be great, because I have no clue what else to try here.
