View Full Version : A bit weird download question
31st December 2005, 04:01 PM
I have downloaded i386 disk 1 iso from fedora website (at least 10 times), done it at friend also...
In most cases sha1 matched - I used HashCalc app to check it
So far I have been using nero (maybe Alcohol once) to burn image on cd.
The problem I get when I boot my burned cd is that it fails integrity check or however this is called, and it says FAILED every time.
Like I said, I've tryed it at friend, at another pc, at laptop.... only thing in common was nero (not same version) and internet provider in which I have great doubts because I have problem with other downloads too.
Is it possible to have right sha1, but failed cd check? Am I somehow burning that ISO wrong way? Or my internet provider really deserves to loose it's customer?

Suggestions: 1). Burn at a slower speed and see if that helps. 2). If you really think Nero might be a problem, try this FREE program that I've used many times (when Windows and I got along) http://www.cdburnerxp.se/ - Just click on the ISO button and follow the steps. 3). If you're up to another bout of downloading, try using these CD's http://fedora.isphuset.no/ - they incorporate most of the recent updates and I've used both versions without even bothering to integrity check and the installations have been perfect.

I would burn at a slower speed, that will most likely fix your problem.

When you check the sha1sum and it is good, accept it. My FC4 cd's passed the sha1sum check and failed the mediacheck during install. I have install fc4 three times, skipping the media check during install and have encountered no problems (that were not self inflicted) with the install or operation of FC4.
Judging from the number of posts on this topic, the media fails frequently.

Hm...about burning speed, I have degraded it to 24x so it should really work on it (DVD recorders that are used are actually new)... I might try cdburnerxp, but I'm fairly sure it will be just another CD in garbage. Actually I might try to download some other linux, burn it with cdburnerxp and see that it does not work either which would definetley lead to low net connection quallity.

Oh, haven't seen your reply weinerdogus, I just bougth Traxdata, was using EMTEC....I will try new media

Ok, it's like this, I have burned iso on Traxdata cd with cdburnerxp on 16x which is drasticly slower then max speed, and there are no reading problems, no wild spins or such (as I said i have new components, so no problem with dust and such). I tried it and got FAILED again. Then I downloaded ISO Buster and checked iso file and burned cd and both reported recovered files with which I really don't know what to do. I downloaded CDMage, converted iso to bin and scaned bin with mage which found 1 corrupted sector (as I expected) and luckly repaired it. I want to mention that originaly downloaded iso had correct sha1! After I burned bin image on another cd (EMTEC and with NERO as I did before) finnaly I got PASS!
After all this I can only blame my internet provider because even though sha1 matched, iso was somehow corrupted.
Thanx for your support and if anyone has some other ideas about what else might be wrong, feel free to post.

Now the question is, will it pass if you run the test multiple times. Maybe its a bug with the checker?

Good point, but I checked again, and PASS. After all corrupted sector was found and was repaired.
