I was trying to clean up my desktop and was dragging things to Trash and by mistake moved the hard disk and I can't get into the trash to retrieve it back, so now i can't access anything on my computer. I am running OS X but i can't open finder or anything else. The funny thing is i did have a firefox window open at the time and it still lets me continue on the internet (don't know why) but everything else is in the trash canand i think it is overloaded so i am frozen and i am afraid to power down the machine becasue then it will permanently empty out the trash can and i will lose all my system applications and software and files. How can i recover my system and not have to reinstall everything? The trash can is Greyed out. Any suggestions to save me?
