I had a problem with Disk Management. I was using Windows 7, but apparently a similar problem could arise in Windows 8. This post identifies a few possible solutions.
First: to get into Disk Management, I went to Start > Run and typed “diskmgmt.msc.” (Depending on the system’s setup, I could also have searched for Disk Management, or I could have found my way there through Computer Management. Tim Fisher provides more information on how to get there.)
This time, unfortunately, Disk Management did not run. Instead, I got an error message:
Disk Management could not start Virtual Disk Service (VDS) on ACER [i.e., the name I had given to my computer]. This can happen if the remote computer does not support VDS, or if a connection cannot be established because it was blocked by Windows Firewall.
For additional information about diagnosing and correcting this problem, see Troubleshooting Disk Management in Disk Management Help.
I also saw that the information bar at the bottom of the Disk Management window said, “Unable to connect to Virtual Disk Service.”
These messages assumed that I was trying to connect or do something involving a remote computer. I wasn’t. I was just trying to start Disk Management to manage the drives on the computer I was using. Moreover, the suggestion to look at Disk Management Help didn’t pan out: when I searched that Help for “unable to connect,” I got “No topics found.” A search for “could not start” yielded two topics, but they were not relevant.
A Google search led to various suggestions in addition to those offered in the error message (above). One discussion asked whether the system was running Windows in a virtual machine, and then suggested checking the event logs or making sure Virtual Disk was enabled in Services.
The latter was my solution. To get into Services, I ran services.msc. I did that by going to Start > Run > services.msc, but I could also have typed “services.msc” at any command prompt, or double-clicked on services.msc in the folder where it was installed. On my machine, that was “C:\Windows\SysWOW64\en-US.” Note: I was running as Administrator; not sure if that would be essential.
In Services, I went down to Virtual Disk. I saw it was set to Disabled. I right-clicked on it and chose Properties > General tab > Startup type > Automatic > OK. That was the solution: now Disk Management ran normally.
