Some of my VM's have this "VM Disk Errors" Error.

Can you please take a look at other VM events happened at that time?

Even though this article refers to Windows Server 2008R2, it still does look that it can be applied to Windows Server 2012.

To address this issue, I have asked our dev team to measure the number of errors per collection interval, so in v7 we will report on errors rate (number of errors per time period) and not only on the actual number of errors occurred.
