Great set of boot and disk utilities. I can get rid of the pile of disks from Seagate & Quantum and use the software on this disk.
Do NOT visit the url listed as the official website. It is overloaded with viral software. I consider myself a savvy user, but I had to restore my windows system from a restore point when I failed to make a legitimate download of UBCD from the site. It makes me worry about the safety of this current sourceforge download.
