SubjectRe: mount failure, SCSI emulation, 2.2.20pre9
More info.  Immediately after a burn and before the CD-R is ejected, it is mountable and has this TOC:

first: 1 last 1
track: 1 lba: 0 ( 0) 00:02:00 adr: 1 control: 4 mode: 0
track:lout lba: 257759 ( 1031036) 57:18:59 adr: 1 control: 4 mode: -1

After ejecting and reloading, unmountable with this TOC:

first: 0 last 1
track: 0 lba: 0 ( 0) 00:02:00 adr: 1 control: 4 mode: -1
track: 1 lba: 0 ( 0) 00:02:00 adr: 1 control: 4 mode: -1
track:lout lba: 0 ( 0) 00:00:00 adr: 1 control: 4 mode: -1

As before, the CD-R is mountable if the IDE CDROM driver is used rather than SCSI emulation. I'm trying 2.2.19, different media and other cdrecord versions. Other ideas appreciated..

Also, apologies to one who wrote me off-list. I unadvertently deleted your email. Please resend if possible.

rgds,
tim.
