The edits were not showing up in the D drive.

I then dragged them from the C drive to the D drive as the D drive is much better. So,when I initially moved the docs from my old computer and then dragged into documents, they first filled up the One Drive and then started in on the C drive.

Once the VM restarts, log back on to the VM. It appears that 'documents' is attached to the C drive.

You will get a warning that the computer needs to be restarted for the changes to take affect.

Select the D drive and then click No paging file and then click Set.

To do this using the portal, see How to attach a managed data disk in the Azure portal. Once complete, Azure will not take back the D: if the VM moves to a different hypervisor.įor more information about how Azure uses the temporary disk, see Understanding the temporary drive on Microsoft Azure Virtual Machines Attach the data diskįirst, you'll need to attach the data disk to the virtual machine. If you have an application that specifically requires the D: drive, you need to follow these steps to temporarily move the pagefile.sys, attach a new data disk and assign it the letter D and then move the pagefile.sys back to the temporary drive. In this scenario, the temporary disk will be reassigned to the first available drive letter. A planned or unplanned maintenance event may also trigger this placement. If you resize or Stop (Deallocate) a virtual machine, this may trigger placement of the virtual machine to a new hypervisor. Never use the temporary disk to store data that you need to keep. If your application needs to use the D drive to store data, follow these instructions to use a different drive letter for the temporary disk.
