Nothing in mind really, just asking. The answer might help figure out what's going on. If adding a session with command-line works like adding it with Nero, that's at least a good thing to know. Smile

PostPosted: Wed 03 Jan 2007, 22:58    Post subject: Multisession Problems
Subject description: I've got lots of multisession problems too...
 

I've been reading with interest this thread about multisession problems that some of been having.

I've been having some mutlisession issues with a variety of "faces" (I mean that there's not just one problem, but a variety of problems) which I've posted over here, with multisession stuff being especially emphasized in my second post (however, some of the other things are also related, like the need for a multisession reboot failsafe which I speak about in my first post that doesn't exist in Puppy).

I have 3 computers on which I've been having multisessoin problems, BUT I also have similar problems with remasters (either not writing anything on the disk at all or with having the disk be bootable after the write). I can't help but begin to wonder if there's a relationship between some of the multisession problems and some of the remastering problems.

I think multisessions is one of the neatest features of Puppy, but remastering also has some really neat features too, like taking the installation of almost 400 MB of Firefox and OpenOffice with slightly less than 100 MB of Puppy bootup stuff (which is about 500 MB added together) and putting all that onto a 212 MB remastered CD! -- wow, that's REALLY cool!. Remasters work very seldom for me, but when it does, it's VERY rewarding, as everything's there (Puppy works, Firefox works, and all components of OpenOffice work too) -- and there's about 500 MB left on the remastered CD for future multisessions (otherwise, it ends up being less than 200 MB on the original multisession disk, and less if you've installed other stuff). Remastering also combines the results of ALL multisessions into a single new session (which is supposed to be like what happens when our multisession disks fill up and we're asked to put in a new CD, but this doesn't work for me well either! -- the disk drawer closes and IMMEDIATELY opens up with nothing written to it!). While remastering is not the issue in this current thread, I wonder if some of these remastering problems are interwoven with or similar to writing usable multisession disks (because I have BOTH of these problems and they have some common features).

Hoping to get some helpful attention to our combined interests, I give you what I've posted here.

PS: Thanks Flash! I just checked my link above and I see you found my other post on your own. Fantastic! See you there...

Flash, I'm looking for your reply to me that you mentioned. I don't see that you've responded here, since this is not the HowTo section that you referred to in this thread. Or is it?

I'm sorry. I thought you were someone else, when I read what he wrote in the Howto section. This is the post I was referring to.

Ok best laid plans of mice and men went astray

hmm...this occured to me also.
The only test I did was with an old copy of 1.09 which behaved perfectly on the same machine so was unable to try the hack.
The disk with which I have noticed the not saving problem was remasterd by hacking the pup_xxx.sfs file to bring the size down so obviously I couldn't test the original(2.2 regression).....no changes in etc or root though...further versions were remastered using the built in script...burned at 4x with nero 6.6 gave reliable results for booting and running.

So apologies for the delay but the subject is not forgotten...I haven't even been near the forum since my last post...lost presumed drunk

regards

Ok finally some results.

I am using a multisession cd not dvd....so I attempted to use the cd parameters for growiosfs...no sucess as the disk is not recognised as writable...ie cdrecord fails to find a sector to write to.

Now this is definately a hardware issue as I tried various puppys...version 1 and 2 and writing the first save worked every time on another machine with a GCE-8160 drive and failed every time on the machine with the Aopen drive.

Now I was never convinced about the quality of the aopen drive as it was inconsistant burning certain formats using nero ,they do not make cd drives any more I believe(!!) and I read bad reports on the web so it would appear if anyone is using a drive with the same innards for example will probably have the same problem.

The dummy track workaround has to be done on a different machine either by burner software or command line as the drive itself seems to decide that the disk is not multisession.

Incidentally results where the same for both cdr and cdrw, and ejecting and reinserting the cd made no difference.

Conclusion...be choosy about hardware

I tried the multisession CD and DVD on several computers. I notice that while the disc seems to work for a lot of the comptuers, it did not work with the Nec 3550A. Not sure why.

Multisession works fine! on DVD.

Problematic:

Asus Spresso 1112
HP USB CD RW external (sorry no model numbers on the case)
Puppy 2.10
burned with TK-cd/dvd (uses burn2iso as backend?) and was using a RW disk.

With a CD the system worked but would at times not seem to pull THE latest session but the one previous. Intermittent problem.

Now:

Asus Spresso 1112
Memorex DVD RW (mfr: 32023292) 16x4x16 internal
Puppy 2.10
burned with TK-cd/dvd (uses burn2iso as backend?) and was using a single layer DVD disk.

With the DVD session support is flawless. Response time is good.

Very Happy Hello Very Happy

@ Equipment: Compaq P3 600 "coppermine" 256cache, 382mb sdram , onboard Intel 82810e graphics, oem compaq bios, Philips pcrw1208 cd burner
Lite-On dvd-rom/cdrw. Multisession CD`s: BuddaPup-215/Teenpup/Macpup/Puppy 215ce/
puppy 109ce/Gamepup216..
Multisession works great on all...
Compaq Evo n610c, P4 768mb ram ati radeon 7500 video, Sony dvd-rom/cdrw. All multisession cd`s work fine..

Really, every multisession cd Ive ever done works great on every machine the live cd ran on..In fact Ive found that it is the easiest way to save sessions for me.

@ Note that I ONLY use BurnISO2cd in Puppy to burn multisession cd`s, although I will use BurnCDCC in windows to burn live cd`s, and have later multisessioned them as well, with varied success. But when burned with burniso2cd they always work fine..

@ Will be trying Dingo next, will post results...
