Hi,
Original question:
---------------------------------------------------------------------
May be I'm doing something stupid, but here it goes anyway:
I think I successfully created a multisession (ISO+RockRidge)
CD (on a Yamaha CDR wit Gear). When I try to access it,
I see only the first session. I think this typically
means that the CD-ROM or the software is not multisession
capable. I have two CD drives: an old (well, nearly 2 years)
Dec drive (come with the CPU) and a Pioneer 1804 jukebox
(with the Tracer software). I also tried the disc on
many other machines (Sun-s, PC-s, etc.). None of them
wanted to read it. Checked FAQ-s, no info about it.
Any idea?
---------------------------------------------------------------------
Well, first the hard facts:
1. I could indeed write a multisession CD with Gear, but first I
did it wrong (no wonder I could not read it).
2. I can not read it:
-- on my 3000/600, OSF 3.0b with a 2 years old Dec drive and
an unknown 3rd party drive
-- on a Sun running Solaris 2.4 with a 2 years old Sun drive
-- on a Sun running SunOS 4.x with a Sun drive
3. I could read it on:
-- my 3000/600 OSF 3.0b with a Pioneer 1804X jukebox and the
Tracer jukebox software
-- on two Mac machines (don't know what they were)
-- on many PC-s running MS-DOS 6.22+WFWG, or Win95
-- on my 3000/600 with the CD-R (Yamaha): I could not figure
out how to use the drive as a CD reader, so it's probably
my fault (I tried to create rz device files as I would for
an ordinary CD-ROM, and also tried the Gear [well, this is
Tracer, too] gd device files used by the mastering software)
And now the rumours, ideas, etc. My feeling is that reading multisession
is more a software issue (I think that some of the CD-ROM drives were
not explicit multisession drives -- whatever that means). I heard rumours that
the next release of OSF (ooops, Digital Unix) and Solaris *will* support
multisession (which again may indicate that it can be done in software).
I also have a feeling that it *might* be possible to do it in hardware,
but this is too fusy for me. Dec told me that there are 3 SCSI drives
out, which are multisession drives: Sony, Magnavox and Apple. I called
Sony and Apple, but they couldn't say anything about the support for
workstations. I could not find Magnavox yet (I found a Magnavox, but it
looked like a company working for the DOD, and I found no phone number
for them -- the web page was concentrating on military applications).
This is the status right now. If anyone (especially Dec) has something
to add, please, please contact me.
