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? ...
