I'm going to give you the benefit of the doubt that you misunderstood my post. The media check that failed was not on the ISOs - it was on the CDs that were burned. The ISOs are good. To be sure, I ran md5sums against them. Got a match. I also then FTPd these ISOs directly from my Red Hat box to my laptop and used them to burn CDs. The media checks from the CDs I burned here (under Win XP)come up perfect. Next, I switched my CD-RW to be Master on the IDE channel and have my DVD-ROM as Slave. Then I burned a CD (Shrike CD 1) at default speed in DAO using XCDRoast. The CD boots on my laptop, but media check from the Red Hat installer fails the CD. Running md5sums against the CD shows an incorrect sum of: 0ff2aa1ced01632c77cfdb7b37f54803 Doing the same on a CD burned with the same ISO, but under Nero on Win XP shows: 400c7fb292c73b793fb722532abd09ad Red Hat's sums on RHN (where I downloaded them from) is: 400c7fb292c73b793fb722532abd09ad And finally, the md5sum of the ISO that was the source of the incorrectly burned CD is: 400c7fb292c73b793fb722532abd09ad ...In other words, a perfect match. So, in conclusion, my FTP download skills should not be called into question, but burning CDs under Shrike using IDE drives should be, IMHO. BTW, I also tried burning from the command line using: cdrecord -v --eject -dao dev=1,0,0 speed=52 /opt/CDTemp/shrike-i386-disc1.iso The md5sum of that CD was: 5d820c2433f5c475efd7971b126f9056 ...Not that I thought this would make a difference. Any other ideas? Cheers, Chris On Sun, 2003-04-06 at 15:10, Robert L Cochran wrote: > Well my gosh! If you fail the mediacheck, doesn't that tell you to > download the media again?
