Description of problem: FC3 ISO files are downloaded corrupt no matter how many different mirrors are used and no matter how many times FC3 is downloaded. Downloaded FC3 Disk 1 and md5sum matched and burned perfectly to CD. Then downloaded FC3 Disk 2 five times from different mirrors and md5sum did NOT match in all 5 cases and burned to CD and CD matched perfectly with ISO file on hard drive but md5sum of ISO file on hard drive did NOT match md5sum of FC3 Disk 2. Checked with www.Linuxquestions.org and a large number of people have complained of corrupt downloads of FC3. Please check this out. I have an AMD Athlon64 3400 CPU with FC2 32-bit version 2.6.5-1.358 kernel. Version-Release number of selected component (if applicable): How reproducible: Steps to Reproduce: 1.Download FC3 ISO files 2.Md5sum them and they NEVER match 3.They fail media-check with FC3 Disk 1 and FC2 Disk 1 Actual results: Corrupt ISO files of FC3 Expected results: All downloads of FC3 ISO files [except Disk 1] are corrupt and fail md5sum and Install Disk 1's media-check Additional info:
This problem could be almost anywhere. The files are probably fine on the mirrors and things are being corrupted en route. You do not say whether you are using FTP/HTTP/rsync/bittorrent to download the ISOs. Nor do you list one of the mirrors you had a corrupt download from. You may be able to patch up a broken download by using rsync or bittorrent to refetch only the parts of the files that are corrupt. (by the way, if the MD5SUMs don't match then it's not even worth trying to burn the CD) Just out of interest do you overclock your machine? Have you had any other trouble with your network connection? Are you using any binary only drivers? Have you had any hard disk errors?
I believe I'm experiencing the same issue. Now, I'm glad (?) that I'm not the only one. By the way, I think this is the same issue that bug #139386 is referring. Even though I didn't perform the checksum verification (via MD5SUM) because I am still using Microsoft OS to download the ISO files, I don't think the corruption of ISO file occurred during the downloading. I'm afraid that there is a possibility of corruption on the original ISO file (on the download site). The reason that I'm suggesting such possibility is: 1. I have downloaded the CD images 4 times already and re-burn the images many times over and over, and they are always bad; 1). Via 'Torrent' over the cable modem connection. 2). Via 'ftp client' over the cable modem connection from the main ftp site. 3). Via 'Torrent' over the cable modem connection. 4). Via 'Torrent' over the dsl line connection. 2. However, that the DVD image that I downloaded while using the same method that I mentioned above is always good. Thanks,
No one mentions WHICH mirrors or WHICH torrents these corrupted files are on. Comment #2, it is possible to get get MD5SUM for Windows (e.g. a quick google turned up http://downloads.activestate.com/contrib/md5sum/Windows/ ) so you can quickly check if a download is corrupt or not. With something like bittorrent makes sure that the download has completely finished downloading ALL files (not just the first) before trying checking them. One known good mirror is zeniii.linux.org.uk. If you download the ISOs from there and find the MD5SUM corrupt then you have reason to suspect the FTP client you are downloading the ISOs, your connection or hardware trouble. I'm not sure that this has anthing to do with the kernel component though.
Thank you very much for letting me know about the windows version of MD5SUM. I guess I didnât try hard. (Iâm also sorry that I didnât specify the location of download and their file names..). However, MD5SUM gave me more questions than answer⦠because I got the checksum match on all those CD Images that Iâve been having troubles with. What does this mean? Does this mean the bug #106685 (please see comment #16 on it) that was reported during fc3-test2/3 is introduced to the final âCDâ images (FC3-i386-discX.iso)? Like I said, DVD image (FC3-i386- DVD.iso) works fine. Does this mean Iâm the one of few people still using the CD drive instead of DVD drive (and DVD media)? I think the best approach we (?) can take at this point is âa trial by another userâ. I certainly donât want to waste developersâ valuable time any more, but I can not imagine why only some users have this kind of problem and they are getting same result (can not install FC3) all the time. So, could anyone try installing FC3 from âFC3-i386-discXâ image and let me know about the result? By the way, I donât know why it was assigned to âkernel componentâ. I donât believe I did that.
Se: If verifying the disks works when you boot with "linux cddma=off" then yes, you are seeing 106685. How you burned the disks can also affect whether you bump into that so that may be why other people haven't seen this problem. Jean: Are you still seeing this bug? If so does booting with "linux cddma=off" help?
I getting the same media check error on the ISO files. I have downloaded them from several mirrors in the North East. See list below. I have currently downloaded and redownloaded the images appprox. 10 times (that's 6.3gig!!!) I have burn 25 or so costers on various machines with Nero, Roxio on WinXP. I have also burned the cd at a lower speed (x4 on x36 media). I have also downloaded from differnt networks ranging from DSL, Cable, and a T3. Nothing!!!!!! What is going on!!!! I'm going to switch back to ManDrake If I can't find an answer.

I am only having a problem with core 3 disc 3. No matter where I FTP it from I get the follwing discrepancy. (my md5sum output) 1e95a10df77165dcdab481bde68a4714 *FC3-i386-disc3.iso <-- my results f88f6ab5947ca41f3cf31db04487279b <--should look this! I didn't have an issue with the other 3 ISOs. BTW, my md5sum results have been the same for every file I have downloaded. Why would disc 3 not download correctly while the others do?
I see nothing here which indicates this is a kernel problem. reassigning to distribution.
I know it's a waste of time, but I went ahead and just burned core 3 disc 3 even with the mismatched md5sum and the media check reported: FAIL! As expected.
Sorry for the additional confusion to this issue, but I can only get this to happen on one PC. I moved to another machine and all the ISOs downloaded and their md5sums were correct and when burned the media passed all four discs too. Both are running WinXP Pro.
Unfortunately, there doesn't seem to be anything here that can be fixed on this end. It does sound like something is frustratingly messed up, but the files do all verify correctly on this end. You may have to avail yourself of the Fedora support options for help.
