Hi! Sorry about the confusion about the Speakup modified Redhat question as regards downloading. I know about the downloading what I meant was testing the download to see if there are no errors in the image which might occur if their are problems downloading which I have like when you have downloaded a zip file, testing it with the facility in winzip to test to see if it has been completed. What I am trying to say is how do you scan the iso files to find out if they have been downloaded successfully when they are on my hard drive so I don't end up wasting a CD on burning an image which might not have downloaded correctly? I notice there is something called Checksum or something like this on the site where the images are. Is that a windows tool for checking the downloaded iso files?
