--- Comment #8 from Matthew Ogilvie mmogilvi2+wine@gmail.com --- No hurry: At least the appdb links to this issue and the workaround, which would have been extremely helpful if it had existed when I first encountered the issue.
As a side note, even though it is easy to work around (once you know how), I'll still emphasize/quote myself about what seems like a conceptual bug that maybe should be fixed anyways:
--- QUOTE --- But it still seems like wine shouldn't get internally confused and return information about writeable "Z:" when the application asks for GetVolumeInformation() about read-only "D:". --- QUOTE ---
