I've already gone to Microsoft support multiple times about this issue. They claim it's "Level 2" service, and that I would need to pay >= $100 for a fix. I realize it's a long shot, but I'm hoping to find a free, simpler solution here. Anyway, I created a backup via external hard drive on an older PC and wanted to access some of that data on another computer. However, every time I attempt to do this, I get a "mounting" error. Tried a bunch of scans and other solutions, but it did not help. Anyone know of any third party software or perhaps an even simpler solution?
