I've been imaging this encrypted partition for years with Macrium Reflect without issue. And these BSODs occurred with 2 different Macrium releases, 7.2 and 7.3, so it clearly has nothing to do with any recent Macrium updates. I've been running Reflect v7.2 without issue since the first release of that version, and now Reflect v7.3 is working well. So I am not saying that Macrium is at fault, just that running it triggered the bug, which ironically appears to be a conflict between a Microsoft AV and a Microsoft driver. Just posted this here in case anyone else sees this error on their machine. Disabling Windows Defender resolved this for me! Never had an issue when I was running Avira AV. Just curious jphughan, what AV are you running?
