When the 2006.1 livecd is about to start loading packages onto my system I get a bad disk sector error and that ends the installation. So far, I've verified the download media with the DIGESTS file using both md5sum and sha1sum and I expect I'll download the public key and verify it with the ASC file too. It makes no difference apparently what kind of install is tried too. I've had this happen with both networkless and internet enabled installs and even with a stage 3 install too. Maybe I need to turn --overburn on to et this working for now I'm not sure.
