I've got a Virtual Machine (VM) that we use for our Terminal Services (TS) server.  Hyper-V is running on a Server 2008 physical Dell PEdge server.

I've had no issues with it up til now.  All of a sudden users were complaining of weird errors in the Apps that they were accessing, mainly our ERP database applicaton.

When I started investigating, I noticed that I could not create any new files or folders on the virtual drive that the VM was running on.

I get the following error:  

An unexpected error is preventing the operation.  make a note of this error code, which might be useful if you get additional help to resolve this problem:

Error:  0x8007045D  The request could not be performed because of an I/O device error.

I can not create a new text file, folder, uninstall any applications, etc, or I get this same error.

I ran a CHKDSK scan on the volume yesterday, and it fixed it, but then the issue came back today.

The drive is overall 65gb, and there is more than 42gb available, according to C: drive properties pie chart.

What could be causing this?  All of the other VMs on the physical host are not having this issue.

I had to shut down the VM and then go into the properties of the VM.  There I compacted the VHD and the problem went away.

Instead of just deleting, #37253212 should be marked as the answer.
