Diagnosing The Problem
There are two options to check the media for the refreshed image:
Option 1: Check the content inside of the HMC_Recovery_V8R8x0_1.iso image with a product such as winrar. The refreshed image will have a new marker file called .version.
Inside the file will be content with a designation -- v1.0 such as HMC850 Recovery DVD v1.0
The .version file does not exist in the original images
Option 2: Check the Recovery media sha1sum values against the refreshed images from June 2016.
Resolving The Problem
Obtain and burn a new image of the Recovery media
