Might there be a corrupt set of ISO files on the download site? http://download.fedora.redhat.com/pub/fedora/linux/core/4/i386/iso/ The last two days I have downloaded the 4 ISO files. Tested media during the install and received a FAIL. With FC1-FC3 I kind of cheated and just downloaded and installed and never bothered checking but this time during an install it stopped part of the way through disc1. I have run sha1sum on the first two ISOs and got the following results: D:\linuxiso>sha1sum FC4-i386-disc1.iso 17540b20a10eceeaf3a38087b1605d8cce1b4a84 FC4-i386-disc1.iso D:\linuxiso>sha1sum FC4-i386-disc2.iso d06d2dfa10404d34a2013a3310529b0e15e0754c FC4-i386-disc2.iso The redhat site lists it to be: FC4-i386-disc1.iso (sha1sum: 3fb2924c8fb8098dbc8260f69824e9c437d28c68) FC4-i386-disc2.iso (sha1sum: 31fdc2d7a1f1709aa02c9ea5854015645bd69504) I'm just wondering at this point, I have downloaded each of those files now 2-3 times and they never match. Thanks
