Twice now I've been busy working in an application (DAZ Studio) that I've been using for a couple of years now.I'm tweaking and rendering and then when I've achieved the result I want I go to save it.Only I can't find my external hard drive..Instead my G: HD drive has become my CD ROM drive.
Now that seems so random...and when I restart the PC it's back to normal.
Weird!!
Not worried yet just puzzled.
