I doubt he'd miss that, and even so, rsync would have noticed the size
mismatch. I suspect we have a timestamp/size match with an internal
corruption.
Monil: add the "-c" (or "--checksum") switch, to force
rsync to do
checksums.
"rsync --progress --archive --partial -vvv -checksum
rsync://carroll.cac.psu.edu/redhat-ftp/redhat/linux/7.3/en/iso/i386/valhalla-i386-disc1.iso"
If it still doesn't detect the difference on the wholefile checksum (i
think it does something a bit less robust and resource-intensive than an
md5sum, and anyway, the only guaranteed-unique checksum would be just a
form of lossless compression), force the file to a new checksum by
appending a byte:
"echo >>valhalla-i386-disc1.iso"
and try again. This will force rsync to use its famous rolling checksum,
which should find the changed bits, wherever they are, and fix them. Make
sure you have enough space in the directory holding the .iso to hold a
second copy during the work.

Looking at this I see a few problems:

This corresponds to about 1 ls, and no data reading.

The speedup is UNREAL, unless you consider that you may have the wrong
path, and you didn't get ANYTHING. What happens if you do a
du -h valhalla-i386-disc1.iso
You probably see that you have an empty file. I'd try good old ftp.
