To Tiger and hinsdale (or other experienced Linux users): OK, I admit I am Linux clueless, but I am PC hardware/user competent. I successfully upgraded to a 40/80 setup last May, and am thrilled to see MFS 2.0 will allow me to go to 120/80 now without losing recordings (and 120/120 down the road a little). As stated above, I want to ugrade just my A drive from 40 to 120 GB - which I am now able to do thanks to Tiger's tools. What concerns me some is my lack of Linux prowess, and the fact the the two statements in the upgrade guides from Tiger and hinsdale that say don't screw this part up are indeed different. I believe that this is due to the fact the the HDs are not in the same IDE ports in the two methods - is it 100% true and typo free, and that both command lines are correct when used with the respective drive locations?
