I used to have trouble burning CDs until I discovered the instructions at http://www.troubleshooters.com/linux/coasterless.htm. Your mileage may vary, but now I always use the following command and don't have any problems: cdrecord dev=0,0,0 speed=16 padsize=63s -pad -v -eject -data /tmp/name.iso Note: to figure out the device, use cdrecord -s -scanbus Note: use a slower speed, if you have a slower CD writer Shannon Troy Dawson wrote: > Hello, > We cannot change the md5sum ... because they are correct. > Here is the output from ftp.scientificlinux.org > > # md5sum SL.305.072605.i386.disc1.iso > a031f04f101f5e627cc95350d2d008a1 SL.305.072605.i386.disc1.iso > # > > I'm sorry your having trouble downloading. > > The CD check also isn't automatic, it asks you if you want to do it, > so I'm not quite sure what you are meaning by this.
