...hmm, I'm getting confused :?

I think it would be better to follow Ted Dog's suggestion:
growisofs -M /dev/dvd -D -J -R /your mp3 books directory
to fill up the DVD.

At shutdown, when it detects the DVD is full, it executes
growisofs -M /dev/dvd=/dev/zero
which is supposed to fill up the rest of the DVD with zeros then close it.
...from what I can understand of your description, it seems to be stuck
at this stage ...I don't know why.
I wonder if TkDVD has something to do with it? Or using a DVD+RW?
...DVD-R may work better.

Maybe I could change rc.reboot-cd so that it doesn't close the DVD.
...there's no essential reason why it has to be closed I think.
---well, except that it makes shutdown neater, as rc.reboot-cd will
detect if a DVD is closed and not ask if you want to save a session
-- at least, I think I put in code for that.

I realize that wasn't very helpful, but I indend to repeat the test, as a learning experience. Eventually, assuming I learn what I'm doing, I'll notice something that will be helpful. Burning and loading such large files takes a lot of time so it will go slowly. I intend to try Ted Dog's suggestion, but first I have to make the folders containing the mp3 files ready on the NTFS partition. It would take me forever to enter all the files on the command line, assuming I didn't make any mistakes.

Meanwhile, here are some more "screen shots"; two of the shutdown and one showing the error messages at last attempt to boot. This is the DVD which was created by the first DVD, which was the one I filled up using TkDVD. TkDVD was not used to put anything on this DVD. I can't remember for sure, but I think it may actually have booted all the way up, the bad sectors no doubt being in the saved mp3 section.

lack of deep relocation flag in TkDVD

#23 Post by Ted Dog »

The TkDVD lacks -D flag support which is used in every DVD supported version to handle directories over (from failing memory) 7 deep. It could cause this error

Ted,

TkDVD was not used at all to write any part of the DVD that was booting when these pictures were made. TkDVD was only used to write the second session of the first DVD. The first DVD then created this DVD automatically because it was too full to hold any more. Everything on this DVD was automatically formed up and written to it by the multisession scripts in Puppy.

wine as a usr_more.sfs works

#25 Post by Ted_Dog »

the Nathans' new wine.gz was converted into a squash file <9M and works very well with the Oct14ms iso. I will upload the usr_more.sfs to my host and provide a link in an hour or so.
:lol:

I thought you had somehow solved that problem without the use of the Archive folder, but that was when I was trying out DVD+R, and the whole thing quit working before I could confirm it. I've switched to DVD-R, which so far seems to work OK, but there is no Archive folder and the stuff I save (in /root) is loaded into RAM every time Puppy boots. This would take forever if the DVD was full, even if I had that much RAM.

On a related subject, does ms Puppy look at the actual size of the DVD, and the actual amount of room remaining? I could use a mini-DVD to speed things up. It only holds 1.4 GB.
/root/archive/ folder is supposed to be there. I don't know where it has got to :?

Ah no, Puppy sees it is a DVD then decides size limit is 4G.
We will have to investigate how to determine if a mini-DVD is inserted.

It took so long to save to, then load from the DVD that I assumed it was reading the large file from the DVD back into RAM. But when I rebooted again, it didn't take long to save the little I had changed, and it didn't take long to load. What's going on, Barry?
I can understand why it was slow to save. growisofs seems to burn a only 1.x times even though we use the "-speed=4" option.
But, I have no idea why bootup was slow ...confused again! :?

I'm doing a lousy job of reporting. One thing I forgot to mention is the DVD burner I used for the testing. It is a Memorex dual format 8x/4x. Perhaps it ignores growisofs speed commands and burns at whatever speed its firmware determines to be best. From the first image in this post, it appears that, when shut down, multisession Puppy saved to the Cheap (2.4x) DVD+RW at an average of 2.1x.

I've got an LG brand burner, model:
HL-DT-ST DVDRAM GSA-4163B

It burns at around 1.4-1.8 times, despite the -speed=4 option.

Media encoded burn rate

#32 Post by Ted Dog »

I read some where that the media has a track on one edge that gives the burn chariristics. I found the -burn speed to be a maxium setting not a minim. feeling ill today sorry for the misspellings. :x ah chooo
