I am no computer expert, but if it’s file size that’s your problem, I had a similar problem once: it may be that your hard drive is formatted using the MS-DOS FAT format, which only allows maximum 4GB sized files. You can buy a drive formatted that way (in my case, a Western Digital) and use it on a Mac out of the box — don’t be fooled by the ‘MS-DOS’ moniker. I erased and reformatted the drive using Mac OS Extended (Journaled) and that fixed the problem.
