JD, errors can pop up in a number of places during the download process. there are 3 things you can do to fix the download: rsync, bittorrent, or metalink. using the latest version of wget is always better than not, but you can't fix this download with wget. (by that, I mean if you've kept the error file & not deleted it). wget will be fine if no errors occur, but the larger the download the more likely you are to run into an error (probably). & you have already gotten errors at least twice. many Linux distributions use metalink or bittorrent for these large ISO downloads to correct errors & for other features like mirror usage. I would suggest using aria2 & the attached metalink file. aria2 is a command line downloader like wget. Fedora already provides metalinks for all their files, but unfortunately they don't include all the repair information, just the sha256sum to detect errors. http://mirrors.fedoraproject.org/metalink?path=pub/fedora/linux/releases/16/Fedora/i386/iso/Fedora-16-i386-DVD.iso -- (( Anthony Bryan ...
