I am getting some strange errors. I have a G5 with a and external 300gb hd. Imovie, when opening a file off the external will often crash, I go to the console and i see many I/O errors then imovie crashing. This happens in idvd too. When exporting to the drive in FCP 5 it fails with an I/O error and dvd studio pro also does this. I think the I/O error is pretty serrious, am i right? should i get everything off the drive? Is somthing wrong with my G5?
