You are correct, becasue hfs doesn't tell wget that the conection is closed, wget thinks that there is still data to retrieve.
http://manpages.ubuntu.com/manpages/lucid/man1/wget.1.htmlWget has been designed for robustness over slow or unstable network
connections; if a download fails due to a network problem, it will keep
retrying until the whole file has been retrieved. If the server
supports regetting, it will instruct the server to continue the
download from where it left off.
solution
run wget with tries option adn no clober option to fix this...
-t number
--tries=number
Set number of retries to number. Specify 0 or inf for infinite
retrying. The default is to retry 20 times, with the exception of
fatal errors like "connection refused" or "not found" (404), which
are not retried.
-nc
--no-clobber
If a file is downloaded more than once in the same directory,
Wget’s behavior depends on a few options, including -nc. In
certain cases, the local file will be clobbered, or overwritten,
upon repeated download. In other cases it will be preserved.
When running Wget without -N, -nc, -r, or -p, downloading the same
file in the same directory will result in the original copy of file
being preserved and the second copy being named file.1. If that
file is downloaded yet again, the third copy will be named file.2,
and so on. (This is also the behavior with -nd, even if -r or -p
are in effect.) When -nc is specified, this behavior is
suppressed, and Wget will refuse to download newer copies of file.
Therefore, ""no-clobber"" is actually a misnomer in this
mode---it’s not clobbering that’s prevented (as the numeric
suffixes were already preventing clobbering), but rather the
multiple version saving that’s prevented.
When running Wget with -r or -p, but without -N, -nd, or -nc, re-
downloading a file will result in the new copy simply overwriting
the old. Adding -nc will prevent this behavior, instead causing
the original version to be preserved and any newer copies on the
server to be ignored.
When running Wget with -N, with or without -r or -p, the decision
as to whether or not to download a newer copy of a file depends on
the local and remote timestamp and size of the file. -nc may not
be specified at the same time as -N.
Note that when -nc is specified, files with the suffixes .html or
.htm will be loaded from the local disk and parsed as if they had
been retrieved from the Web.
