UDF CDs
Thomas Tempelmann
There seems to be a lot of confusion and misinformation about UDF. Let me makes these things clear:
1. Adaptec/Roxio sold a software called DirectCD for Macintosh. I was the author of this software (along with someone else who did the low level driver, which is not relevant here, though), so I know quite well about this.
2. While DCD is not maintained by Roxio any more, there is still a free "driver" to read DirectCD formatted disks, called "Adaptec UDF Volume Access". This software only works with old Mac OS 8 and 9, not with OS X, though. You can download it here: Update Toast 4.0 Deluxe or later to version 4.1.2
3. Apple's own UDF support is limited to the original UDF format (rev. 1.02), which does not support DirectCD formatted disks. Later, UDF was extended to version 1.50 and 2.0, both of which support writing to CD-R and CD-RW in ways that DirectCD, WriteUDF!, PacketCD and other packet writing tools use.
4. When you "close" a CD-R using DirectCD on a PC, another format, ISO 9660 with Joliet, is added to the disk, and only then you can read such a CD on a plain OS X system, because OS supports the Joliet format. If the disk is not closed, you might be able to read such a CD using a CD recorder and the UDF software from Software Architects (www.softarch.com), but I can not promise that as I've not tried this software myself.
