DPM unable to backup files from specific HDD

Hi there,

I'm having trouble with a certain Machine in our DPM system. It appears to have trouble backing up the content of one particular HDD. DPM states that the replica is inconsistent.
There are certain characteristics about this HDD that should be noted: It is a Virtual HD (VMWare), it was previously attached to a different server and has since been relocated to this server.

There are 3 drives on the server in particular. C: & E: backup fine. However F: does not backup at all.
I've tested putting an identical directory with 3 files totaling less than 100KB and it will still fail to backup.

I'll attach a bunch of screenshots soon for your viewing pleasure.

The affected server status under the 'Protection' view. The list of failed Jobs.
What is shown when you click the "details" link at the bottom of the second screenshot?
Do you have any events from source "VSS" or "Volsnap" on the hl-neptune server?
What happens when you manually create a VSS snapshot of the F:\ drive on hl-neptune?
Check if the SYSTEM account has "Full Control" permissions on the root of the F:\ drive.

Clicking details just shows the folders.
The error i think you are after is: The replica of Volume F:\ on HL-NEPTUNE.x is not consistent with the protected data source. DPM error ID = 51. (ID 33123)

System has Full Control permissions on the root of the F drive.

I've attached an image with the logs from HL-NEPTUNE. It doesn't appear to have any errors (at least not as frequently as its trying to Sync. But it does have DPMRA & Vole Shadow Copy Service starting and stopping often.

I ran a custom log view for VSS & Volsnap for all logs and all that came up were many logs with 'The VSS service is shutting down due to idle timeout. '
Big Business Goals? Which KPIs Will Help You

The most successful MSPs rely on metrics – known as key performance indicators (KPIs) – for making informed decisions that help their businesses thrive, rather than just survive. This eBook provides an overview of the most important KPIs used by top MSPs.

OK, so the logs don't seem to give you any clues.
What is the OS on HL-NEPTUNE
What happens if you manually create a shadow copy of f:\?
I assume F:\ is an NTFS volume and not a FAT volume?
Forget the OS question. I can see from the screenshot it's W2k8R2.

OS is Server 2008 R2

F: is an NTFS volume.

I've manually tried a shadow copy and it appears to have been successful. Screenshot attached.
Ok, that all sounds fine.
Is there anything that could help us in the DPM-specific event log on the DPM server? For example, is there a further indication in that DPM-specific event log of the errors during the Consistency Check you ran yesterday at 11:39AM?

Unfortunately there isn't any logs as far as I can see. I'm surprised myself.

On a side note.

I copied 25 percent of the data to a new HDD (just setup) on the same server. Then ran DPM over it and it replicated fine.

Appears to be a problem with the HDD or the settings.

This issue may now be resolved. I had a major issue with one of our SAN's. The end result is that I was required to Duplicate the Virtual Disk. Also (it may not have anything to do with it) but I renamed the virtual disk to something more in line with the name of the Server. It was previously assigned to another server.
