Firstly I am the creator of this thread and I welcome you to post whatever you please in here, so long as it is compliant with the site ToS and relevant to the topic. Your question was fair and relevant IMO... your second post not so much, but it is your first post I am referencing here. So here's the answer:
The issue was I uninstalled Daemon Tools while still having an image mounted on the virtual drive it provided. The result is, while Daemon uninstalled properly, the virtual drive it created did not. The VDiskBus error was coming up for me because Daemon tools did not fully uninstall the files associated with the virtual drive (drivers
, etc.); as I'm sure you've experienced, you cannot delete files that are currently being used; the virtual drive was being used during uninstall hence why some files were not removed and hence the error.
Now this might not be the reason why this error is occurring for you, this is specific to having this error after uninstalling Daemon with an image still mounted. Ditto for any other program that does the same thing Daemon does. If this does not describe your situation however, it is doubtful the solution in here will be of help.
I am no expert so I would suggest you do post in your thread for any additional help regarding your problem.
