BE2012 SP4 - Displays Storage Capacity as "1E+03GB free"

One of our BE2012 SP4 servers (Windows 2008R2SP1) is displaying Capacity on its primary backup device (a locally attached RAID) as "1E+03GB free", as shown below:

 

 

I have performed the following, with no change in results:

• Stop and Start all BE services
• Reboot the server
• Inventory & Catalog the storage device
• Used the local BE console on this host and used a remote console on my workstation - resulted in same view.

Backups appear to be running normally.

None of our other BE servers - which have a similar hardware configuration and same size or larger backup volumes - are exhibiting this behavior.

I am concerned that this might be more than a display error and at some point impact the integrity of the backups.

Any thoughts?
