Help with alchohol 120%

im trying to mount an image on a virtual drive.but it always says “file not accesible”. I have other images in the same exact folder and all the other ones are accesible. please help.

Well, what sort of image file is it?

its an MDS file. so are all the other ones.

What application did you use to make the image? Try again; this time using ImgBurn.
