Need help diagnosing corrupt ISOs installing FC6
I installed FC5 just before 6 became available so I decided to get 6 and install it.
I downloaded it, burnt it to disk using the same burner I used for FC5 and tried to install it. During the disk check it said it was corrupt and not to use it. I figured maybe the disk was bad or it was a bad burn so I reburnt the file. That disk failed the check too so I re downloaded it from a different mirror. That one said it was corrupt as well so I downloaded bit torrent and downloaded the bit torrent file. I burned that to disk and it failed the test. I cleaned the lens on my internal cd read drive and my external burner then burnt a new disk and got the same results.
I have a hard time beilieving it was a problem downloading the file since I tried a few different options but I also have a hard time believing it is my burner or my bootable CD drive since that is how I installed FC5 with no problems.
Any ideas on how to trouble shoot where the problem lies?
