Thanks for that suggestion. If I only had one .mov file in question that would be logical, however, this is happening with all of them and I have about 50. No matter which clip I choose (clip.mov) they will not copy from one drive to another. Each .mov clip is 6 to 7 gb but they all give the error at the 4gb mark. I have tried numerous clips. I have used firewire drives, internal drives, and 2 different macs. I have changed firewire cables. I have repaired permissions. No matter what, when I try to simply copy any random .mov quicktime file from a random drive to another to create more space for myself they all fail. I can copy a Quicken financial file, I can copy a Word document, I can copy any number of Mac related files on my hard drives between each other quickly and effortlessly. But I cannot transfer .mov files between discs. I have 10 DVDs. I am ripping each one into .mov files by scene. 5 scenes per DVD which means 5.mov files per DVD for a total of 50.mov files total. Then each .mov file is converted to .wmv files in 2 minute sections. I will have hundreds of .wmv files when this is all done. The whole process takes massive amounts of storage which is why I am using 3 or 4 drives for ripping and converting. But it's a real problem now to have ripped so many .mov files only to discover they cannot be copied or moved to another drive for the conversion phase of the job. One final note: I searched at Apple Discussions and found one other post from a month ago from someone who had the SAME problem. But no answer was given. So I know I am not the only one who has experienced this. Perhaps someone out there could try it themselves? Duplicate the problem and see if it happens? If you have a .mov quicktime file over 4gbs try and move it to another partition or drive. Thanks again for all the help.
