The resulting mess can usually be undone manually via the PE build's drive managment interface, but it's one of those cases of "good intentions" paving the path to hell. Otherwise, I like their backup utility very much, especially the user interface which is much superior to Paragon's IMO, and I've purchased a full single Reflect Pro license for further experimenting. It's required for entry into Macrium's own forums, BTW.
I'm still looking for whatever WinPE setting or component triggers that Reflect behaviour, but I've had no luck so far and I've heard nothing further from Macrium. (Typical British reticence. Copy of my follow-up below.) If anyone else succeeds in discovering that trigger, please pass it along.
Hello John.
Thanks for your kind consideration of my developmental inputs. Much appreciated. In the meantime, however, if it's not a deep dark secret, perhaps your developers might be persuaded to reveal the "trigger" for that Reflect behaviour in Windows PE environments. If allowed to know what WinPE component or setting causes it, especially the drive letter re-assignments, I might be able to find a temporary workaround pending the developers' ultimate decision about providing a start-up command switch.
I do realise, BTW, that it is done with the best of good intentions -- i.e., recreating the "normal" drive letter assignments for the end user. Unfortunately, however, it completely messes up Windows PE environments where the application programs drive letter is specified by the PE build itself. Other than that, I like the Macrium backup utility very much, especially the user interface which is much superior to Paragon's IMO. (The less said about Acronis' latest misadventure, the better.) I've now purchased a full single Reflect Pro license for further experimenting since it's required for entry into Macrium's own forums.
Best regards,
Richard Virtue
