@xubin I tried unlocker as you suggested but it says that the file is not locked.
@signals I do not have the drive set to auto eject.
Here are the steps to help reproduce the problem:
Open DVDFab (I'm using 8.1.1.2).
Select Blu-ray Copy -> Main Movie.
[SIZE=3]Select the source folder (in this case I'm selecting a folder on the hard drive that was already ripped from disc).[/SIZE]
[SIZE=3]Select the target folder (I'm using a folder on a drive different from the source).[/SIZE]
[SIZE=3]Select the first title on the disc (only to help speed up the test/process).[/SIZE]
[SIZE=3]Select BD25 (or whatever) and click Next.[/SIZE]
[SIZE=3]Make sure Create miniso to mount the folder in DVDFab Virtual Drive is checked and click Start.[/SIZE]
[SIZE=3]When done the target folder should open, leave DVDFab alone and double click or right click on the miniso file to mount the image.[/SIZE]
[SIZE=3]For me nothing happens. When I right click on the DVDFab Virual Drive icon in the system tray it shows it as mounted. When I go to My Computer and right click on the Virtual Drive to view it's properties it shows type: CD Drive, Used/Free space 0 bytes, Capacity 0 bytes (i.e. it's not mounted).[/SIZE]
[SIZE=3]Back to [/SIZE]DVDFab[SIZE=3], click OK on the Process Completed Successfully dialog, click Finish and exit out of DVDFab completely.[/SIZE]
[SIZE=3]Since DVDFab Virual Drive THINKS the disc was mounted, right click on the miniso file or on the DVDFab Virual Drive icon in the system tray and unmount the disc from the drive.[/SIZE]
[SIZE=3]Double click or right click on the miniso file to mount it again and this time it will work (only works for me when DVDFab is closed).[/SIZE]
[SIZE=3]This happens everytime I try it without fail.[/SIZE]
