Aplogies if ImgBurn already does this but:
I use ImgBurn under W2K as a convenient and reliable way to burn ISO images to disc. These are usually downloads of LINUX images, etc.
It would be nice if the reverse could take place, insert the OS disc and create an ISO Image to hard disk. This would be useful for long term archiving, CDROMs are not to be relied upon for long term storage, or for mounting with say Daemon Tools or as VMware CDROM images.
