    When I get trouble with my external or flash drive I'd rather never take risks, so I always get all my files off, and just use the Disk Utility, and format the drive. Most problems get solved doing this.
    You could google it, and run down some threads started on other forums, but thats up to you...

    good luck

    Is your external formatted FAT32? If so this is a file size limitation of the file structure and you'll need to format it HFS+

    Is your external drive formatted as HFS+ (Mac format) or FAT32 (old PC format)? Most drives come formatted as FAT32, and do not support files larger than 4GB. You get a similar error to this if that is the case. The new PC format (NTFS) does support larger files, but Macs can't write to it without a system extension.

    On this explains it...

    So FAT-32 doesn't do files over 4GB eh? Hmmmmm that might also explain why my other 200GB+ external drive couldn't accept this 6GB file on Windows. ... Well I'm screwed. My drive is a 1TB external so I'm in the same boat as the OP with all my life's works on it and no other storage options so that I can re-format the drive. BLARG...

    i had the same problem when trying to copy a series of video files and folders adding up to 70 GB roughly, i overcame this problem temporarily by copying them folder by folder... i then noticed that the error message only appeared when i tried to copy a .ISO file which was included with the video files. i don't know why this happens but i mounted it and am now copying the files from it one by one.

    Workaround for copying large files to external Fat32 formatted drives (error 0)

    Stuffit allows you to break up files into any size segment and then move the pieces under 5GB (say 4.9GB each) to the Fat32 Drive. It reconstructs it like .rar does (or just do a .rar compression but stuffit doesn't seem to have that).

    Fat32 drives seem to be a necessary evil for people with media players (I use the Asus HDP-R1 Media player with USB or eSata drives with movies/music i download--plays them right to stereo system or flat screen, no running expensive cables out of the back of my mini anymore). For 80 bucks, it's pretty sweet (though i do recommend the Western Digital unit--way better interface). The Fat32 Drive format is the most native for the Asus but will recognize HFS too i'm pretty sure. I just have a PC and a mac I download movies/music to and move the drives around a lot between them.

    another workaround

    I couldn't copy a .dmg file (4.66GB) to my FAT32 formatted USB drive. I dbl-clicked it to mount it and I tried copying the contents to my USB drive (4.8GB) and it worked. It copied error free. It seems that you just can't copy archive files (.zip, .dmg, .rar) larger than 4GB. Weird, huh?

    My guess is that each of the files within the archive were below the single file size limitation of FAT32 and that is why this appeared to *Solve* the problem.

    hmmm I see im responding to an old thread. Oh well hope this helps someone else.:D

    thanks for fix

    it certainly did. had multiple isos in a folder - to large to copy whole folder, but went over individually fine. the whole folder copied over to my time machine disk (for a temporary test), just not my FAT32 - here's me thinking fat32 is the 'best' format!

    Rename your folder for "*.zip" and try!

    ExFat format will allow transfer of larger files. Works well with the Mac. Not supported in Windows 7. But did find a patch for Windows XP.

    Regardless of the fact that you're responding to a thread from last year, exFAT IS supported by Windows 7. It was developed by Microsoft so it would be odd for Windows 7 to not support it.
