Incredible....We are in this situation after some close to 30 years of having error-correcting protocols.....Unbelievable :-( .
I use a Firefox Extension called DownThemAll! which has never given me a bad CD or DVD - and it resumes from where I lost the connection (which never happens now :-) .) I also find that the downloader in Firefox now also resumes from where the connection was lost and it also produces a "clean" file - but this latter downloader has not been under any "real strain" since it was upgraded by Mozilla.
Notice that this doesn't guarantee a correct download, the http or ftp protocols don't allow that. You need something else for verification of the download, and then retry. This can be automated, but you need a verification method. For example, if the download manager knows the expected crc, it can insist downloading chunks until the result is good. But blindly, because it can not know what section of the file has the error. -- Cheers / Saludos, Carlos E. R. (from 11.2 x86_64 "Emerald" GM (Elessar))
