sha256sum fails for Fedora-11-i386-DVD.iso

I am having issues verifying the images DVD iso image for FEDORA 11 i386: the "sha256sum" utility keeps complaining about the ISO image:
$ ls -l
-rw-r--r-- 1 user1 users       1604 2009-07-02 15:01 Fedora-11-i386-CHECKSUM
-rw-r--r-- 1 user1 users 3683829760 2009-07-02 15:50 Fedora-11-i386-DVD.iso

$ curl https://fedoraproject.org/static/fedora.gpg | gpg --import

$ sha256sum -c *-CHECKSUM

sha256sum: WARNING: 7 of 8 listed files could not be read
sha256sum: WARNING: 1 of 1 computed checksum did NOT match
I have downloaded the ISO and the checksum from at least 4 different sites:

I have also downloaded the checksum from different sources and verified that all checksums files were identical. Now if I could only get the ISO file to match them!

Anyhow, I generated the checksum using the sha256sum utility for the ISO downloaded from ftp.linux.ncsu.edu, and it came up with:

efb6b85e0140d460ccaedc36f1737a321b22ff20b115591e00824a2fed8384b7 *Fedora-11-i386-DVD.iso

That checksum is very different from the checksum being distributed by the fedora project, which is:

6e812e782e52b536c0307bb26b3c244e1c42b644235f5a4b242786b1ef375358 *Fedora-11-i386-DVD.iso

I am going to go to a computer on a different internet connection and which is running windows to see if I get different results, but I would be surprised if the results are different...

Anyone have other ideas on how to solve this? Where did you download your image from? Did your checksum match the checksum above (available at: https://fedoraproject.org/static/che...-i386-CHECKSUM)

FYI, I have checked the Harddrives and RAM on this machine. Memtest86 (from my old fedora distro) ran for 12 hours last night: 9 passes and no errors...

I still dont know what caused the issue,but I was able to download the iso from a windows box and the sha256sum check was successful... FYI, I did read somewhere in the fedoraproject site that some programs have issues with files over 2GB... but I dont think that was the issue for me, unless bittorrent clients have that problem!

That is strange, I wouldn't worry though because I thought torrents solved the problem of corrupt downloads as it regularly checks the downloaded file during the download and at the end. It is more likely that the checksum file may be inaccurate, as that can be let down by human error, rather than the ISO being corrupt.
