Partition above extends beyond the end of disk

I was recently trying to backup a server using Symantec Backup Exec System Recovery (BESR) 2010.  Unfortunately, BESR was refusing to create a backup.  A support call to Symantec pointed us to the PartInfo.exe tool, located in C:\Program Files\Symantec\Backup Exec System Recovery\Utility.  Running this tool creates a text file called partinfo.txt in the same folder.  When PartInfo was run on this particular server it logged the error “Partition above extends beyond the end of disk”.  This machine was a virtual server running on Windows Server 2008 R2 and had converted from a physical machine.  I was able to resolve the error by shutting down the VM and increasing the size of the disk by 1GB (the smallest amount permitted by the System Center Virtual Machine Manager 2008 R2 GUI).  I restarted the VM, re-ran PartInfo and the error was resolved and BESR was able to take backups of the server.
