Polaroid BurnMAX24 CD-RW

Polaroid BurnMAX24 CD-RW

[Mark Johnson]

I am once again in need of some help.  I just got a new CD-RW . It is a 
Polaroid BurnMAX24.  I was wondoering if anyonr knew if there are 
drivers available for this or if there is a generic driver used?  I 
tried rpmfind.org but I couldn't connect for some odd reason, and I 
thought there was a linuxdrivers.org or something but couldn't seem to 
find it either.  The docs for the drive say it is a CD-WRITER IDE2410. 
 I tried Polaroid but they don't even mention a cd of any type, and the 
search program gave me nothing to.

I don't know the specific drive you mention, but typically IDE CD-R/W drives
are standard. They are a bit tricky to use, however, in that Linux
CD-writing software only knows about SCSI drives ... so you have to use
SCSI-IDE emulation in the kernel to access the device. This basically
requires loading a bunch of modules, plus passing a parameter to LILO that
causes the appropriate IDE device NOT to be mounted as an IDE device (so the
module can pick it up pater). Then software ike cdrecord can access the
drive via its pseudo-SCSI parameters, and more standard software can access
it via (usually) /dev/scd0 .

If you don't already know about doing this part, post again and I'll give
more details (or track down the URL of the pretty good HowTo I've seen) then
I ccan dash off from memory. If you alrady know this part and are asking
ONLY about the particulars of this drive ... then I apologize for wasting
your time.

I added the list back in. My substantive reply is below.

There is a CD Writing HowTo that covers the basics of how to do this; find
it at (for example) www.linuxdoc.org . It is slightly out of date, but you
should be able to get what you actually need to do worked out without too
much difficulty from the information it presents.

Here's what I did ... influenced a bit by my use of Debian, so the details
for your distro may vary a bit.

1. Compile the needed kernel options as modules. My notes say I did it this
way (on kernel 2.4.17, using "make menuconfig") --

        in IDE/ATA/ATAPI BLock Devices, I enabled a module
for "SCSI emulation support"
        in SCSI, I enabled "SCSI disk support", "SCSI CD_ROM
                support", and "SCSI generic support"
                all enabled as modules

2. Since I had already compiled my own kernel, I could compile these modules
incrementally, with "make modules". Then I moved the newly-compiled modules
into the kernel modules area (I did this with "make modules_install").

3. I then added (in /etc/modules) the modules I neded to modprobe in at
boot/init. That list is:

# the stuff to enable ide-scsi emulation for the CD-ROM
scsi_mod
sr_mod scd0
sg
ide-scsi


4. Last, I modified lilo.conf so that the IDE CD-R/W drive would NOT be
initialized as an IDE devide at boot (so the ide-scsi module can grab it
instead). I made this change (the last line shown) to lilo.conf:

image=/boot/vmlinuz-2.4.17
        label=Linux
        read-only
        append="hdd=ide-scsi"


The hdd part is because I connected the drive as IDE secondary/slave. You'll
need to modify that for wherever you have yours connected (hdb, hdc, or hdd).

I then re-ran LILO, successfully.

5. With all the changes made, I rebooted. Everything worked for me, and I
now had the drive installed as device /dev/scd0 . The easy test of this was
to use it as a CD_ROM reader, putting in an iso9660 disk and mounting it
successfully.

6. cdrecord is a bit weirder. It doesn't use the /dev/scd0 pseudofile to
access the drive; it uses its (pseudo) SCSI parameters instead. The easy way
to find them out is to run 

        cdrecord --scanbus

to get it to find the drive. Once it does, use the reported values to access
the drive. For example, after I've created a filesystem image with mkisofs,
I use this command --

        cdrecord dev=0,0,0 speed=24 filename.iso

where the dev= part is what you get from the prior command, speed= is the
write speed of your drive, and filename.iso is the image you want to put on
the CD. This is for a write-once disk; there are other options if you want
to do multisession.

I've only done this a little bit myself, so there are, I'm sure, many other
oprtions, once you get the basics working. 

Hope this helps. Good luck.

 I remember having lots of trouble getting cdrecord set up correctly last
year, at that time some of the problems were probably due to moving to a
2.4 kernel. I'm including the following from my modules.conf in the hope
that it might be useful to somebody. I've got a CD-R on what used to be
/dev/hdb, and a CDROM on what was /dev/hdc, both accessed as if scsi, but
a zip drive on /dev/hdd accessed as an ide device. 

# cd record, and try to use ide-scsi for /cd but not /zip
pre-install ide-scsi modprobe -k ide-floppy
alias scsi_hostadapter ide-scsi
alias scd0 sr_mod # load sr_mod upon access of scd0
alias scd1 sr_mod # load sr_mod upon access of scd1
pre-install sg modprobe ide-scsi # load ide-scsi before sg
pre-install sr_mod modprobe ide-scsi
# load scsi_mod before ide-scsi, sr_mod
pre-install ide-scsi modprobe scsi_mod

Actually, you don't need to do this append any more, at least if
modules.conf is correct!

 Strange, it's usually the writer that is the problem. I know nothing
about KOnCD, but I've used X-CD-Roast to copy audio tracks from _my_
CDROM, which is technically a DVD now that I think about it. I read you as
saying you're trying to copy audio tracks.

 Your modules.conf looks reasonable. 

 Both of my devices work through ide-scsi. If I want to mount a filesystem
from them, one of them is/dev/scd0 and the other /dev/scd1. You say you
can access the dvd ok through linux, except from the cdrecord or the
graphical front ends, so which device do you access ?

 It's the best part of a year since I got my setup working, so the detail
is getting a little hazy. I'm assuming both the DVD and the CDRW are ATAPI
devices and using SCSI emulation, but your comment that you added the
alias for scd1 makes me question exactly how you have them, and the
kernel, configured. My memory says that if you compile ide-cd into the
kernel you will not be able to use a CDRW as a scsi CDROM. Hmm, apart from
writing to the CDRW, can you successfully mount an (iso) data CD in it
using /dev/scd0 ?

 Also, which kernel ?

Re: Polaroid BurnMAX24 CD-RW

[Ray Olszewski]

If I read this right, the CD-R/W on hdd works fine, but a separate DVD 
drive on hdc does not work (in SCSI-IDE emulation).

If the DVD drive is an IDE drive, you can either access it as an IDE device 
-OR- add it to this "ignore" line and let the SCSI-IDE stuff pick it up. 
But you can't do both.

But ... in the modules.conf file, you only have one IDE device in the 
ignore line:

 > options ide-cd ignore=hdd        # tell the ide-cd module to ignore hdd

You need to tell the IDE stuff to ignore the DVD drive as well (apparently 
hdc from what you wrote below) if you want the SCSI-IDE modules to manage 
it. (Once again, I'm not sure of the exact syntax, since Debian handles 
modules a wee bit differently from the RH-descended distros.)

This is all a guess, of course, since I'm interpolating a lot to fill in 
blanks. How, for example, do you now access the DVD for playback? I'm 
guessing /dev/dvd symlinks to /dev/hdc, not to /dev/scd1 . If so, that's a 
sure sign that you haven't moved it from IDE to SCSI-IDE.

BTW, Ken, I have IDE-CD compiled in my 2.4.17 kernel, and I can access my 
CD-R/W just fine. I do need to include an append= line in lilo.conf telling 
the IDE stuff to ignore hdd, so the SCSI-IDE modules can later grab it. I 
don't know if Mark's use of ignore in modules.conf completely substitutes 
for this, or if his method only works when ide-cd is a module.

I may be jumping in the middle of a converstion here, however from experiance 
my comments are pasted inbetween the lines below.

^^^^^^^^^^^^^^^^^^^^^^^^^^

Why exclude an ide cdrom, if i do not exclude my cdrom which is also /dev/hdd 
xcdroast finds it and i am able to use both cdroms.
exclude it and i cant use it in xcdroast.

It will only see the cd-rw because you have excluded /dev/hdd via 
/etc/modules.conf

You can indeed use ide-scsi for 2 cdrom devices, however xcdroast is somewhat 
funny when it comes to 2 scsi devices.

Possably a question of having one ide device defined in /dev as (possably) 
/dev/cdrom1 > /dev/hdd ???

I dont think kernel version's come into this question, more a question of 
what is compiled into ones kernel.
I always say use a bog standard kernel (example of that is the distribution 
kernel installed when you installed linux). Too find out whats going on of 
course...

O yes and if my comments are considered unvalid, sorry..

Re: Polaroid BurnMAX24 CD-RW

[Ray Olszewski]

Mark, let's keep this discussion on the list, please. I've added it back 
here in a Cc:.

If you run the command "ls -l /dev/cdrom", you will (almost certainly) find 
that it is not itself a pseudofile entry. Instead, it points to something 
else, probably /dev/hdc . That's what a symlink is, sort of (read "man ln" 
for the details).

Once you moved the drive to the IDE-SCSI driver, it was no longer 
accessible through /dev/hdc, so the /dev/cdrom symlink no longer works. You 
now have to access it at ... well, I don't really know, but /dev/scd1 is a 
good bet.

The mount points you are using are set in /etc/fstab . In there is 
(probably) a line that tells mount to mount /dev/hdc on mount point 
/mnt/cdrom, and to mount whatever the pseudoSCSI-CD-R/W device is (maybe 
/dev/scd0) on /mnt/cdrom1 . Or the mount points may use the symlinks 
/dev/cdrom and /dev/dvd instead.

In any case, once you know where (in /dev) the device pesudofile entries 
are, you can edit /etc/fstab so the mount points connect to the right 
devices (or to suitable symlinks).

As before, this includes a lot of guessing, based on teh way my Debian 
systems set themselves up out of the box. YMMV as to the dtails, but this 
should be enough to get you started in teh right direction.

sorry about that, I noticed the other previous ones went straight to you 
also.  I didn't catch it before, but I got this one:).  Usually when I 
reply it automaticly goes back into the group instead of to the sender.

you're right (except fstab uses /dev/cdrom as hdc and /dev/cdrom1 is 
hdd), and that is why the dvd stopped working.  When I installed the 
cd-rw it linked to cdrom, which is the dvd.  the cd-rw is cdrom1.  now 
that I have dvd as ide-scsi it is now cdrom1.  will it mess up anything 
if I just rename crom1 to cdrom and vice-versa so drive 0 is cdrom amd 
drive 1 is cdrom1. it is confusing having drive 0(cdrom1) as 1.  as for 
it not working after the changes, it was the burner programs wanting to 
have the cd ejected, it resets the cd somehow, mad a bad cd curn as I 
was burning too fast for the prgram and got data underflow.  I slowed 
her down and everything is running pretty smoothly.  I've done about 5 
tests so far with no glitches yet (fingers crossed).

good guessing.  You were right on 100% both times with a couple minor 
(obvious) changes on my end. The only problems I really had were a few 
program glitches and me being in too big a hurry and missing a command 
or two.

Again, thanks for the help.

 Thanks, Ray. I always find the interactions between ide and
scsi-emulation confusing.
