When you’re executing the csupload tool to upload (or create) a Windows Azure VM role, you may encounter an error which says The VHDs Logical Size of (whatever)MB Exceeds the System Maximum of 66560MB. The cause of this is because the virtual machine you are trying to upload is larger than 64GB. The maximum size of a disk for a virtual machine you’re placing in Windows Azure is 64GB.
