ADDENDUM

A suggestion to the SANYO engineers

Our current understanding of CDR technology suggests (at least to some of us) that the BURN-Proof feature can be enhanced in the following scenario not currently supported. If an operating system or other software related crash occurs, the drive should be able to store the last EFM address recorded on special non-volatile RAM by making use a specifically designed on-drive FIFO. Additionally, a special "signature" of both the recording application and the last to-be-recorded disk should be stored on both this RAM and a "special" area on the disk. After reboot, with the last "coaster" disk still inserted, the recording application should be able to inquire the drive and derive the exact location on the disk (MSF) where the recording error occurred.

Under a predefined protocol, which both the drive and the recording software are able to understand, recording should be able to continue even if an error of such a severity ever takes place! All this can be handled through some proprietary extensions to the MMC-2 specifications and requires an agreement on the type of "hash" used to describe each recording application (name, version, etc) and the type and some other specifics of the image disk. If all this is possible, then CDR technology will be so much BURN-Proof as hard disk writing currently is ;)

So unless a system crash renders a user's PC inopperable, BURN-Proof technology should be able to protect his drive from any other buffer underrun error of less severity:)
