使用Azure SDK 1.6 ，在Web Role和Worker Role里加载Azure Drive没问题。但是在VM Role里加载会出现以下错误：
CloudDriveException 0x80070103 When Using Windows Azure Drive from a VM Role
和微软的Andrew Edwards 讨论，发现是驱动的问题，需要手动安装驱动。
The workaround for this issue has been published to MSDN: http://msdn.microsoft.com/en-us/library/windowsazure/hh708321.aspx.
On the virtual machine, navigate to
C:\Program Files\Windows Azure Integration Components\v1.6\AzureStorageDrive\Open the wadrive.inf file in text editor.
Replace the one occurrence of %ARCH% with the five characters amd64.
Replace the one occurrence of the six characters $ARCH$ with the five characters amd64.
Locate the CatalogFile entry that references the wadrive.cat file:
CatalogFile=wadrive.cat
After the CatalogFile entry, add the line:
DriverVer=06/21/2006,6.0.6002.18464
Save the modified file, replacing the original wadrive.inf file.
On the virtual machine, open to the device manager. Click Start, right click Computer, and clickManage. This opens the Server Manager.
In the left navigation pane, expand Diagnostics and click Device Manager.
Right-click the top node in the details pane. Click Add legacy hardware.
The Welcome to the Add Hardware Wizard opens.
Click Next, select Install the hardware that I manually select from a list (Advanced), and clickNext.
Click Show All Devices and click Next. A dialog on which you are instructed select the device driver you want to install opens.
Click Have Disk…. In Copy manufacturer’s files from: type the path to the wadrive.inf file.
C:\Program Files\Windows Azure Integration Components\v1.6\AzureStorageDrive
Click OK. The Add Hardware dialog opens with WA Drive Miniport driver highlighted.
Click Next and click Next on the following dialog. The Windows Security dialog opens to verify the driver installation.
Click Install and click Finish.
