I know I can use bin2iso or bchunk to decode it, but I'd rather keep the block metadata intact from the file itself instead of having the burner/driver(?) reconstruct it. I assembled a small stack of coasters by trying a few combinations of -d, 'raw', etc, to no avail. The best I got was from raw, a track which needed to be read with 2352 byte blocks, so it wasn't being interpreted as metadata. I presume if I were to dd this entire disc into a file, I would have a verbatim copy of my original, albeit less fault tolerant. Can this be done with burncd? How does the drive/driver know to interpret the remaining 304 bytes as metadata? Is it possible to extract the full 2352 byte blocks from a track which is advertised as only 2048, ie a typical data track? There are a few Windows apps for doing exactly this. thanks, sh To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
