Last night I was trying to install Leopard on a friends macbook, I took my hard drive to back up everything and do a clean install of leopard, just like I've done a few times already. I was using Super Duper to backup everything, and it got stuck on some file about 15 mins in. I let it run for another 15, then it came back with an error. I then tried Carbon Copy Cloner, and i thought it was gonna work but just as the progress bar was getting to the end, the same error came up. One of the two programs says its an input/output error and the log showed me which file is causing it. I dont remember exactly where its located, but the file is called "Playmovie.action" What should i do? Erase this one file, hope it doesnt mess up a program, and restart the backup? Or is it something else thats causing the error? Should I give up on the clean install and go for the regular Upgrade path? Another thing, she currently has a partition with Vista on, installing leopard shouldnt erase it right?
