I am new here and looking for inspiration please. I have been using Vegas 9 platinum for nearly a year with much hassle. Recently we changed the PC we edit with and added an external hard drive for storage. I have started to notice that when we save a finished work to the external or internal hard drive after a week or so we seem to loose part of video or some are merging with others. An example is I edited a 10 minute clip which I saved as AAA. It comprised of about 20 clips and 6 text clips. Two weeks later when I went to open it again an error message said clips 1, 4, 7, 12 were missing. After it has searched it found the missing clips in a file called CCC. It has done this a couple of times since but each time the missing clips turn up in other random files not the same one. Any help or advice appreciated please. PC is running Vista Pro.
