OSR 5.0.7 and DVD compatibility

[C. Coulter]

I have recently downloaded the updated WD driver for
OSR 5.0.7 (which promises DVD writer compatibility).
However, after closer reading of the associated man
page, I find that writing CD's/DVD's appears to only
be supported by commercial products such as BackupEdge.
The only noncommercial product mentioned was cdrecord
(which does not have the most recent version, which
supports DVD+RW, available for OSR).

Is it possible to use the tools inherent in the operating
system (such as tar or cpio) and/or open source tools
(such as gnu tar or others) to write to CD's/DVD's if
you have the updated WD driver? Or is the only way to
use a commercial product (yes, I'm aware of the qualitative
differences)?

Thanks for your time and valuable input,

ATAPI CD & DVD writer support is in the base OSR507 release. The "Wd
Driver Supplement" you downloaded adds support for >137GB IDE hard
drives (only on systems with SCO Update Pack 1 installed). It does add
ATAPI CD/DVD writer support to OSR506, perhaps you were mislead by that
in the docs.

You don't need a commercial product. It's true that to date the
operating system doesn't include a program to write to CDs & DVDs; the
added support in OSR507 is at the driver level, making it possible for
such programs to work.

`cdrecord` is available in the SCO Skunkware collection
(www.sco.com/skunkware). It can definitely write to CDs. I've never
figured out whether you _must_ have the DVD-enhanced version to write
DVDs, or whether it only adds special DVD features like support for UDF
filesystem format. Maybe someone who actually has a DVD writer can
comment...

Microlite's BackupEDGE and Lone Star's Lone-Tar support DVD writing.
Both are very well regarded by members of this newsgroup. Both offer
time-limited demo versions on their web sites. You might want to try
them and see whether they're worth the money to you.

Bela:

The release notes for the updated WD driver show the
following statement in the "What's New" section:

# ATAPI CD and DVD writer devices now supported

That is why I downloaded the update.

Does anyone else have any thoughts on this topic?

Thanks,

I don't have a DVD writer, but I read on the cdrecord home page,

http://www.fokus.fhg.de/research/cc/glone/employees/joerg.schilling/private/cdrecord.html

that "DVD writing support is implemented in cdrecord since march 1998."

The latest Skunkware version of cdrecord is from source that dates to the
middle of 2001.

The current alpha version of cdrecord (2.01a19) compiles readily on OSR
5.07, using either cc or gcc.

And here's the good DVD news from Microlite for 506 users.

I'm sure Lone-tar will be doing the same now with 506.

LONE-TAR version 4.0 and greater already has support for ATAPI DVD and CD
writers under SCO 5.0.7. LONE-TAR supports these devices under 5.0.6 with
the installed wd supplement just the same. There are no additional
patches or updates required for LONE-TAR.
