OT: "Proprietary" CD/DVD "formats" (layouts)
Hi, Way OT but worth a shot... I've historically imaged each of my (COTS) distribution media as a backup against loss -- floppies, CD's, DVD's -- even *tapes*! This lets me "mistreat" the originals...

RH "requirements" for (COTS) optical media
Hi, I was rearranging the media closet and noticed the "hieroglyphics" on one of the (blank) optical media spindles. Appears to suggest an RH range of 5-90%. I can understand the high end limit...
