Is there a way to read a DVD written on a Windows 10 PC thru OpenVMS/I64 8.4?
I know about MOUNT/MEDIA_FORMAT=CDROM for ISO-9660 CDROMS. Apparently
most field-recorded DVD's are in UDF format (not ISO-9660).
I'm archiving OpenVMS BACKUP .BCK container files that have been ZIPped
and then written to optical media on a PC workstation.
It would be handy to be able to directly restore those ZIP files on
Sure. But you already know how. Load the disk on a Microsoft Windows
system or another box that supports the format used, and transfer the
files over to OpenVMS via the network. Or tell the Windows system to
generate the files using ISO-9660:1988, if whatever tool you're using
here even allows that. "No built-in support exists within OpenVMS for
creating nor reading those features of ISO-9660:1999 not in
ISO-9660:1988, nor for various extensions to ISO-9660:1988 including
Joliet, Rock Ridge and HFS." But as for UDF support on OpenVMS, it's
not available. There was a third-party product from the folks at
USDESIGN — the whole web site is gone — that had something related
years ago but I've never encountered that product and don't know if
it's still around in some form. There are also open-source and
third-party tools for writing CDs can support the format. Just not
reading it and recovering the data on OpenVMS, AFAIK.
In short, the answer hasn't changed since some bozo posted the following:
If you're re-doing this media creation process to switch over to
ISO-9660:1988 sans extensions, I'd probably also get rid of the BACKUP
savesets (or would create a parallel set of archives), and would use
zip 3.0 or later (as available) on OpenVMS with the "-V" switch.
Quote that switch, or use extended parsing. Removing the BACKUP
wrapper means that other systems can at least access the text files in
the archive, without having to scrounge up and get BACKUP or an
open-source tool that can (sometimes) read BACKUP savesets involved in
the restoration. Less work, fewer tools, etc.
