title: How do I add instance storage to an existing Windows EC2 instance?
body: <p>I have a Windows 2008 EC2 instance to which I have done some customizing on the EBS boot drive.</p>
  
  <p>I started the instance as m1.small (or m1.large) and the instance storage does not appear as an additional drive.</p>
  
  <p>I've read that the -b switch in the ec2-run-instances command allows you to create mappings for the ephymeral instance storage. The ec2-run-instances command creates a new instance, however, in my case, the instance already exists and therefore I start it as ec2-start-instances, which does not have a -b switch for ephymeral instance storage.</p>
  
  <p>Is there any way I can get to the ephymeral instance storage that comes with an m1.small instance for my existing EBS-booted instance?</p>
  
  <p>UPDATE: It seems that nowadays (Feb 2015) Windows machines mount ephymeral instance storage in the Z: drive.</p>
