:I get the following error when I try to burn a CD with burncd:

:I believe this is EROFS. Here's the relevant dmesg lines:

Synchronize to the latest HEAD, make sure you do a full build/install
    of the kernel, world, and also do a make upgrade.   Also note that
    when burning a CD you have to use the raw CD device (e.g. /dev/acd0,
    not /dev/acd0c).

I had a similar error in an earlier HEAD, and I did fix it.

I sync'ed to HEAD and enabled NATA in the process. Did a full
build/install kernel, world, and did a make upgrade. I am now getting
this error:

josepht@tin$ sudo burncd -v -s 10 -f /dev/acd0 data

The non-zero LBA is due to me trying this command several times on the
same blank disk. I am assuming that this is not causing the problem
and don't want to waste a bunch of disks testing this out. If this
could be causing my problem let me know and I'll try a brand new blank
disk.

Here are the relevant lines from dmesg:

atapci0: <Intel ICH7M SATA300 controller> port
0x18b0-0x18bf,0x376,0x170-0x177,0x3f6,0x1f0-0x1f7 irq 18 at device

ata1: <ATA channel 1> on atapci0
acd0: DVDR <PIONEER DVD-RW DVR-K16A/1.63> at ata1-master UDMA33

(my HDD changed from ad0 to ad1 which I assume is from switching to
NATA).

There are no errors in dmesg from the failed burn attempt.

Thanks,
Joe

Oh, one more thing... when you are doing a test burn (or a real burn),
do NOT ^C burncd, it will leave the CDRom drive in an unusable state
that will probably need a power cycle to fix.

Mmm.  Bad assumption.  Try a new disk, and put it in test mode so it
    doesn't actually write to the CD (so you don't wind up hucking too
    many of them into the trash).  That's -t to burncd.

Same error with a brand new blank disk and using -t.

ls -la /dev/acd0, this is what it should be:

test28# ls la /dev/acd0
    crw-r----  1 root  operator  117, 0x10010000 Jun  8 18:08 /dev/acd0

It is:

Also after running burncd with -t I tried running it again and got
this:

Does that LBA 712 mean that something was actually written to the CDR
with the -t flag?

It is saying error 5, which is EIO.  Maybe the problem is the 10x
    writing speed?  Try -s 4 instead of -s 10 maybe?

I don't know what's going own with the writable LBA of 712.  Maybe
    that particular drive doesn't support test mode.  Weird.

I can burn CDs with burncd and acd0 on my test box, so I'm fairly
    sure the protocol is working properly in HEAD:

test28# burncd -v -s 4 -f /dev/acd0 data /usr/release/dfly.iso fixate
    adding type 0x08 file /usr/release/dfly.iso size 278234 KB 139117 blocks

I tried -s {1,2,4} and all returned EIO.

When I first got this laptop before I installed DragonFly I booted it
with the original Windows XP install and a dialog box popped up that
asked if I wanted to use the drive in DVD or CD mode or some such
rubbish. I am wondering now if there is some config register in the
hardware that has to be set to switch between CD and DVD modes (I
guess for writing since reading CDs works).

After rebooting the LBA restarted at 0 and increments after each
attempt.

Wait.  Did burncd EVER work on that laptop with DragonFly?  e.g.
    1.8, before all the work I did this last month?

-Matt

I never tried. So many things on this laptop didn't work that burning
CDs was pretty low on my list. I did try playing a DVD with no
success.

Ok.  I don't know if the problem is due to recent changes or if it's
    a long term issue.

One last thing you could try is cdrecord.  cdrecord takes some getting
    used to because it uses the SCSI API and it is kinda messy.  Even though
    it is still talking to the same ATA device, there's a chance it might
    work where burncd doesn't.

Get cdrecord from pkgsrc via sysutils/cdrtools-ossdvd

It has a test mode also.  Basically it works something like this:

cdrecord -scanbus

Figure out what scsi device the ATA CD-Drive attached as.  That's
    the device you specify in the below commands.

cdrecord dev=1,0,0 -checkdrive

This will print out the drive information.  It may ring a bell with
    someone.

cdrecord dev=1,0,0 speed=4 -v -dummy -sao ISOFILE

This does a burn.  I think. (in dummy mode == test mode).

Hey,
I'd just like to add that burncd has never worked for me either. its been
very long since i tried last time though. Maybe i should find my cd-rws
and try again..

cdrecord works.

Joe

I strongly recomment to use the primary version, it should support
anything the ossdvd patch was supposed to add and it is more actively
maintained. Doesn't change any of the rest.

Joerg

should we keep this bug around until burncd is fixed?

I say close it. The CDROM drive seems a bit flaky anyway.

:priority: -> bug

No, close it.  burncd is effectively just a simplified version of
    cdrecord, it isn't going to work on all CDs.
