its almost as if 120 decides which systems it works on, i have known of it totally destroying operating systems, and i know this for a fact, and i have known it working better on older OS's , it totally inniliated my drives... i still have like 4 i cant get rid of, without reformatting... it screws around with your comp 2 much..... Use Daemon to mount and Ddump to make the ISO's i would give u links but i am kinda busy.... the 120% sucks... and 9 outta 10 says your gonna have to do alot of work 2 get it fixed... try uninstalling it and reinstalling it, could fix the problem you are having...... but be sure it is totally and completly gone before you install Ddump IF you try it... take care dude, hope the advise helped any at all..
