i just updated to mac lion os and after that, everytime i plug in my usb or hard drive, the icon doesnt show up on my dekstop anymore and when i looked at my finder, it was there and can be accessed thru the sidebar, but i find this rather troublesome since i have to open finder all the time and i just want it to pop out on my dektop everytime i plug it in. how can i have it appear on my dekstop again ? thankss
