I apologize if I'm missing the bus here, but for some reason I recently came awake and noticed packet-writing for what it could be. In reading the history and archives I can find, it seems most people are concentrated on using RW media for temporary storage - "floppy replacement" kind of stuff. My interest is in using it with R media as a poor-man's WORM drive substitute for storing log files, but I'm not finding much reference to anyone doing so other than claims that it "can be done." I've tried a superset of all the instructions I can find, but thus far have succeeded in nothing more than making a couple of coasters - dvd+rw-format seems counter-intuitive on write-once media.
This list seems to have really slowed down in the past couple of years, but I hope there are still enough knowledgeable people watching this list that can answer my [hopefully] elementary questions:
- It has been stated that CD-R (and presumably CD+R) media is not supported for use; is that due to lack of software or that the physical medium itself cannot be abused in that manner?
- Has anyone actually ever successfully used DVD-R (or DVD+R) media to store 'immutable' data? If so, can you list the precise steps, drive, and media (if relevant) you used to do so? The ability to actually [physically] delete things from RW media defeats my intended purpose.
- Does pktcdvd gracefully handle concurrent, incremental file writes (read: log files), i.e., can blocks be interleaved or must an entire file's worth of blocks be allocated at once? Note - this question is due more to my lack of understanding of the UDF format than anything.
Whatever the answers, I'm certainly willing to learn & get my hands dirty trying to get this working, I'd just like a few things cleared up so I know what I'm getting into.
Thanks for your time!
RB There was a MS Windows program called "Direct CD" that provided "letter access" access to a CD-RW media. I do not believe it worked with CD-R, as

In the mean time re: "Worm", I would seriously consider DVD-RAM. This is a $50 drive with $8.00 media, that reads/writes as if it were a hard disk. The media is perported to be of better quality than the other CD DVD media. Some drives use a cartridge, the newer ones do not. You can format (via MS Windows only, I believe) as FAT32, UDF 1.5 or UDF 2.0. UDF 2.0 has larger "clusters" so it is more efficient with very large files (multimedia). I use FAT32, not because I use MS Windows, as I use Suse Linux, but because I can use it easily in Dosemu to run DOS programs (Foxpro mainly) under Suse. Hope this input helps, -- John R.
