I am just trying out O&O DiskImage Pro on Windows 8/64. Created a data image without any problem, however when I try and mount the image as a drive it does not assign a drive letter although it says it has. Using Paragon HDM I can see the image has been created in a partition but no drive letter, nor is it possible to assign one. I had a similar problem with Paragon but with that it BSOD'd. Anyone come across this problem?
