I have been so busy lately, but finally was able to participate in this thread. I made a sardu disk about six months ago, but for some reason it doesn't boot any computer i have tried it out on. i didn't throw the disk away because i considered the possibility that it could still offer something beneficial (perhaps data at the very least), however i also made a sardu flash drive and that works beautifully. every antivirus updates and scans properly. The utilities and linux distros also are accessible. obviously, i like the way the flash drive works. I think it's great to have davidecosta here at wilders with us. Thanks for your hard work davide.
