Server 2012 Domain Controller Logging event 2004, with error "crc check"...

Question

Pretty new domain, and domain controller, running server 2012 as a Hyper-V VM.
Getting this error when it reboots.  I have done a chkdsk, thinking maybe the vhdx file is corrupt in some way.  Have also checked the system log for events talking about file corruption.  Nothing.
The disk in question has 10+ GB free, so disk space is not an issue.  I ran dcdiag /q /a & it told me that DFSR has logged events in the last 24 hours, but nothing else.  AD seems to think everything is cool.
Not sure what to look at next...  Thanks for any pointers/help.
The DFS Replication service stopped replication on volume C:. This failure can occur because the disk is full, the disk is failing, or a quota limit has been reached. This can also occur if the DFS Replication service encountered errors while attempting to
stage files for a replicated folder on this volume. 
Additional Information: 
Error: 23 (Data error (cyclic redundancy check).)
