Hei Headrush

Well, that was a surprise.. I was 100% sure the tarball had been removed on this system, but... RC_DEVICE_TARBALL="yes" is still in /etc/conf.d/rc so I guess the tarball is still around! Do you have its location off the top of your head?

I'll get rid of it straight away and see what the /dev/pktcdvd contents are then. I have another copy of Gentoo on my second disk, and have definitely removed the tarball there.. thats why the mix up ;-)

regards

edit: I found it in /lib/udev-state
edit2: I went back to tarball="yes" after a monumental screwup, during which a hang 'ruined' the mounted dvdrw media.
I also found my second copy of Gentoo too had tarball="yes".

After finishing writing and unmounting the disc, if I leave the disc in the drive, the write light continues to constantly flash.

I have removed the disc and remounted it and all seems everything was properly written.

Anyone else see this behaviour?

Hei again
No the led on my drive hardly flashes at all, even when playing music via kplayer... right now its unmounted and no flashing. Mind you I haven't written to it for a while.. as soon as abcde finishes ripping a new CD for me, I'll write it to /mnt/dvdrw and see what happens

mvh

Edit: the blinking lasts a minute or two with 60MB sized copies.

Well setting thing up an keepin' it a-going was okay.
I miss using that feature for ordinary cd-r.. would be nicer just to 'cp' them via Eterm than starting K3b an searching first, then burning and after that having forgotten what i burned... see cd-r is more reliable.. you write it, it won't get killed ever (k maybe it becomes hardly accessible coz of a screwup in UDF-Sessions or whatsoever.. i'm pain-proof concerning packet writing since my first cd-writer (Ricoh..).. any of ye know CeQuadrat? That damn thing ruined many of my cds, i can tell ye..
whatever, that was not what i wanted to discuss with ye.
What i wanted to discuss is:
followed all instructions (good boy), that tarball thing is enabled by default since i switched to udev (i don't understand that automount though.. i insert cd, cd to /mnt/cdrom or whatever, do ls -lA, see... nuttin.. mount it in that ordinary, enerving way (you get real pains if ye got to skip through bout 20 DVDs an always mount/umount..) mightbe i just have to mount, eject, insert and do ls again? ) but i keep changing subjects.. what this post shall be about is:
i did
Code:

mkudffs /dev/hdc #which is my BenQ DW800A +/- DVD-Writer

worx. nice thing.. spits me some output, but seems friendly output, so i dont give a crap, do
Code:

mount /dev/hdc /mnt/dvdrw

an <zap> System freezes, all activity stopped, got to use that darn Power-Switch (next time i started i put AC/DC into me XMMS "Flick of the switch" ^^ that only as a little anecdote (misspelling?) )
now i didnt have the guts to try it again since i dunnot like system freezes, and holding down that PS is really annoying (4secs are damn long ^^.. and i don't have my reset switch plugged (plugged it some day wrong direction, never changed it, doesnt work^^)
Any one got an idea what stoopid-me did wrong concerning that freeze? (not concerning the novel i wrote 4 u ;) )
if ye wanna tek a look at me fstab:
Code:

/dev/discs/disc0/part1  /boot                   ext2            defaults                1 2
# /dev/hda3             /                       ext3            defaults                1 2
/dev/discs/disc0/part8  /                       reiser4         defaults                1 2

/dev/discs/disc1/part9  /home/morimando/space   reiser4         defaults                1 2

none                    /proc/bus/usb           usbfs           defaults                0 0

#Packetwriting.. should be a good idea
/dev/pktcdvd/yamaha     /mnt/cdrw               udf             noauto,noatime,rw,users 0 0
/dev/pktcdvd/benq       /mnt/dvdrw              udf             noauto,noatime,rw,users 0 0

yeah i know, it looks kinda messy ;) that udev took me by surprise as i passed gentoo=nodevfs udev to kernel, an suddenly all hda and sda and such disappeared at boot time.. poor noob that i am i was kinda lost for about 1min then i wrote that fstab u see over there an.. well it works..

So thanx for reading all the crap i produced here, hope one has an idea.. ill try to get it working myself, an if i succeed i'll post it te ya, mightbe with a solution (but i doubt i'll get it)

one last word ^^: before any questions appear: yes i HAVE problems getting to the point and writing short and precise.. i'm a linguist, not a technician.. studying english, german and philosophy, so i guess my feminine part is more evident than the logical one *hrhr* (didn't meant to offend any gals here, some of ye are indeed very logical thinking (i suppose) :twisted: )

Hei
here is my fstab a) for the packet writing dvd+rw, and b) for my dvdrom
Code:

/dev/pktcdvd/dvdwri  /mnt/dvdrw  udf  noauto,noatime,rw,users 0 0
/dev/cdroms/cdrom /mnt/dvd iso9660,udf  user,noauto,ro  0 0

If you do
Code:

# cd /dev/pktcdvd/
p4pe pktcdvd # dir


you should see something like:
Code:

0  control  dvdwri  pktcdvd0

and If you do
Code:

# cd /dev/cdroms/
p4pe cdroms # dir


you should see something like:
Code:
 cdrom
linked to hdd &/or hdc

though mine is a bit odd due to an udev rule I need to fix.. ;-)

mvh

all dem files seem te be right..
Code:

pktcdvd $ ls
0 1 benq control yamaha

Code:

cd /dev/cdroms
cdroms $ ls -lA
cdrom0 -> ../ide/host0/bus1/target0/lun0
cdrom1 -> ../ide/host0/bus1/target1/lun0


seems right to me, doesn't it?
Well after i spent half the night copying my /dev/hda3 to /drives/drive0/part8 to start my system from 12GB Reiser4 instead of 4GB ext3 (which ran low on space), it seems like all dev's are now correctly set to udev-style, so i'll try again, i think (but am not sure) the problem was i flicked the udev switch in bootparameters
Code:
gentoo=nodevfs udev
, but forgot to set new root from /dev/hda3 to /discs/disc0/part8, so all things concerning hardware were a bit upside down and inside out so to say. Booting speed kida sped up, although "mounting devices" takes about 3-6secs.
Another weird thing is that although kernel hasnt changed and config files shouldnt have changed also, my "ae" turned to ]. my "oe" to [ and my "ue" to @.. kinda weird, but i think ill get that sorted till evening.. ill get back to you asa i know if packetwriting works or if system continues freezing ;)

I like giving to you the following news:
Code:

mount /pktdvdrw/benq /mnt/dcdrw

works. cp files from disk to DVD also works, speed seems okay also, just transferred about 200MB for testing purposes, took about 1 minute, many up/down spins though, but works nice..
so after im successful with that.. how do we get CD-R to work for packetwriting?
maybe also mkfsudffs ? i'll try, if it works, there'll be a posting here in about 5 to 10 minutes, if not.. ill wait for some qualified answer ;)

trying to change type of multiple extents... what's it want to say to me?
k mkudffs can't be used to format cds directly (however with dvd it aint a problem), tried
Code:

cdrwtool -t 16 -d /dev/pktcdvd/yamaha -q
-> setting speed to 16, using device /dev/pktcdvd/yamaha, open cdrom device: Input/output error
# same happens with /dev/pktcdvd/0
# with /dev/cdroms/cdrom1 its slightly different:
setting speed to 16
using device /dev/cdroms/cdrom1
7294KB internal buffer
setting write speed to 16x
Settings for /dev/cdroms/cdrom1:
        Fixed packets, size 32
        Mode-2 disc

I'm going to do a quick setup of /dev/cdroms/cdrom1. The disc is going to be blanked and formatted with one big track. All data on the device will be lost!! Press CTRL-C to cancel now.
ENTER to continue.

Initiating quick disc blank
wait_cmd: Input/output error
Command failed: a1 01 00 00 00 00 00 00 00 00 00 00 - sense 05.20.00
blank disc: Illegal seek

i get the slight impression CD-R won't work, am i right?

next edit: mkudffs formats the DVD from whatever point im approaching it, now way to get it disoriented or even fuzzy, /dev/hdc works, /ide/host0/bus1/target0, /dev/pktcdvd/benq /dev/pktcdvd/1 /dev/cdroms/cdrom0 .. all up & running ready to format discs *lol*
but (when having CD-R inserted, didnt try CD-RW yet, will do in 15secs.. k did it, works..
although trying /dev/pktcdvd/yamaha told me -> can't unlock door (for whomever to step in) neXt try /dev/hdd worked, right now he's formatting (takes its time... dvd is formatted faster)
.. any of you tried cd-r-Packetwriting?

This is a bit old but it makes the point about cr-rw (also applies to dvd+rw) media
Quote:
Packet writing
..is a method quite different from TAO and DAO; it is designed for writing data to CD in small increments. Packet writing must be supported by hardware (not all CD writers support packet writing).
The largest benefit in packet writing comes in its ease of use; packet writing enables the user to copy files to CD without mastering any images previously, allowing someone to copy files to CD without requiring significant technical knowledge.
Combined with a CD-RW drive and CD-RW media, packet writing provides an extremely simple, versatile, and inexpensive method for performing regular backup of crucial data.

Well me again .. forget anything i wrote above..
built my system udev only, means there ain't a tarball around anymore, and devfs is wiped out.

edit 1: deleted the crap i did to that cdrw script ^^
it is as follows:
Pure udev system, ivman hal, dbus installed, udftools and those tools for cdrw installed.
Code:

df -a

tells me i got 2 writers.. ivman set them in fstab itself (n!ce), but for whatever reason it mounts them to /media/cdrecorder (and /media/cdrecorder1) so thats why i didnt recognize earlier that the automount is working and also the reason i didnt test that earlier.
Now that i recognizes it, i unmounted the dvd-writer (had a DVD-RW inserted) did a quick mkudffs /dev/hdc, worked fine.. eject, reinsert (or mount yourself, however) and there it was, beautifully set to /mnt/dvdrw and working just like a charm, without the need to start any script or such, damn, its feeling like real Plug & Play action here ;)
so i just need to change the mountpoints ivman set and whooop there ye go :)

edit 2: Using the Ivman/hal/dbus trio, cdwriting is really easy, you dont need using scipts or such any more, i dont know if that also works on a devfs based system since i lack the possibility to test it, but at least on pure-udev all you got to do is checking that "managed" is in your fstab at your cd/dvd writer and also there has to be "rw" in it to tell it you can write that media.
shall look like this (approximately)
Code:

/dev/hdd                /mnt/cdrw               auto    exec,user,noauto,managed,rw 0 0
/dev/hdc                /mnt/dvdrw              auto    exec,user,noauto,managed,rw 0 0

hdd/hdc should be automatically used by udev since it shall detect your cdrom is capable of writing media ;)
Have a nice day and let me know if that works for you :)
I'm actually pretty happy with it :)
edit 3: wiped out my question above since it kinda solved itself ;)

At last, I got things working.
The problem for me was that the packet device created by UDF is buggy.
I removed it and created a new one with pktsetup, and it worked!
This seems all logical now, because before I had those "directory errors".
I think this is a bug in udev.

Great! welcome to the packet-writers club :-)
The howto is a bit of an assault course isn't it, but its worth it..
I like having my music on dvd+rw, and find copying nested directories across from harddisk with krusader works both fast & reliably.
Mvh

Sorry to ask a silly question, But can i still use my drive to watch a dvd or listen to an audio disc using dae method? Also can i still use a standard iso9660 disc (both reading and writing with say k3b) ?

Hei dan2003

Well, just to be sure, I changed my kaffeine and xine settings to point to /dev/hdc my 3520a packet burner, and played back an audio CD and then a DVD. Next I used partimage to write an image backup of my 2.8GB portage partition, and finally I selected a vfat folder containing 1100 jpg files (with Konqueror) and said burn with k3b.. no problem. My fstab entry looks like:
Code:
/dev/pktcdvd/dvdwri  /mnt/dvdrw  udf  noauto,noatime,rw,users 0 0
/dev/hdc   /mnt/nonudf   iso9660,udf    noauto,noatime,ro,users   0 0

This has been quite a struggle...

I have tried to pick up instructions from different sources, and have followed much in this thread. I am unable to format a disk:
Code:
$ cdrwtool -d /dev/hdc -q


I repeatedly get the following:
Code:
I'm going to do a quick setup of /dev/hdc. The disk is going to be blanked and formatted with one big track. All data on the device will be lost!! Press CTRL-C to cancel now.
ENTER to continue.

Initiating quick disc blank
wait_cmd:  Input/output error
Command failed: a1 01 00 00 00 00 00 00 00 00 00 00 - sense 05.30.05
blank disc: Illegal seek


How can I troubleshoot this to get packetwriting working?

Does anyone have any thoughts??

Thanks...

Hei, yes it can be quite a fight ;-)
If you start with page3 joseph''s post onwards you should make it. btw, the following is key..
Code:
/etc/conf.d/cdrw
 # List the CD-Rom drives you wish to enable packet writing on here.
 # Some examples follow:
 #cdrw_list="/dev/hdd"
 #cdrw_list="/dev/sr0 /dev/sr1 /dev/sr2"
 #cdrw_list="/dev/cdroms/cdrom0 /dev/cdroms/cdrom1"
 cdrw_list="/dev/hdc"


Do you have a cd or dvd burner?

What version of kernel are you using?

Have you enabled the following in the kernel?
Code:
CONFIG_CDROM_PKTCDVD=y
CONFIG_UDF_FS=y
CONFIG_UDF_NLS=y
and do you have cdrw in default runlevel?

Have you the latest udftools and dvd+rw-tools?

You may have noticed, ref. udev, I still use the tarball=yes to avoid setting up
Code:
pktsetup dvdwri /dev/hdc
after each boot.

btw what do you have in /dev/pktcdvd/ ?

I haven't played with cd-rw for a while so I'll have a go now and refresh things.
All the best, packet writing is definitely worth it!
Mvh

Edit: just realized you have the same error as Morimando a little further up this page, which he got when trying to packet write on a cd-r if I remember correctly..

Cintra...

Thank you for taking the time to help me with this issue!

Here are the answers to your questions...

/etc/conf.d/cdrw: Yes, I have exactly the same script.

Do you have a cd or dvd burner? I have a Matshita DVD/CD-RW

What version of kernel are you using? I'm running 2.6.11-gentoo-r9

Have you enabled the following in the kernel? Yes, all three kernel options are enabled.

and do you have cdrw in default runlevel? Yes, cdrw is in my default runlevel.

Have you the latest udftools and dvd+rw-tools? Yes to udftools... No to dvd+rw-tools - (don't have at all)

ref. udev, I still use the tarball=yes to avoid setting up pktsetup dvdwri /dev/hdc after each boot: I don't really know what that means... please elaborate.

btw what do you have in /dev/pktcdvd/ ? I have as follows:
Code:
total 0
brw-r-----  1 root root 254,  0 May 30 14:55 0
brw-r-----  1 root root 254,  0 May 30 08:45 cdwri
crw-rw----  1 root cdrw  10, 61 May 30 14:55 control
brw-rw----  1 root cdrw 254,  0 May 30 14:55 pktcdvd0


Edit: just realized you have the same error as Morimando a little further up this page: Yes, the search worked to get me to this thread!

I hope this proves useful... I'm still fairly new with linux and full of many questions!

Thanks, again, for your time!

Ok it looks pretty good cgmd..

My RC_DEVICE_TARBALL reference concerns udev and is setup in /etc/conf.d/rc.
I guess you are using udev?

As yours is not a dvd burner, you shouldn't need dvd+rw-tools.

If your initial error was with cd-r media, please try again with cd-rw media, Verbatim for example.

Mvh

Btw, do you have the possibility to packet format a cd-rw disk using inCD on XP?
If so it would be interesting to see if you could mount the disk on gentoo and 'drop' something to it..

Another question.. are you able to write to a cd-r and/or cd-rw using k3b for example?

Cintra...

'top' shows udevd running...

I'll get hold of a cd-rw media today and try it.

I'll download inCD to my XP pc and give it a try... also, after I get the rw media...

I don't have kde on my laptop, so I'm not sure about k3b...

Thanks, again... I'll keep you posted!

Cintra...

Having aquired a couple blank CDRW's, I went to Josehp_sys's instruction:
Code:
you should be able to mount your cdrw if it is formated.
You can format the CDRW as packet writing as normal user:

$ cdrwtool -d /dev/hdc -q


I have successfully formatted 2 CDRW's for packet writing! :)

Now, since I have no desktop environment as of yet, I want to be able to copy or move files to the CDRW, using command line entries.

If I want to copy data files from a directory to a CDRW, what do I do? I have no earthly idea of the command to do so! :?
Code:
$ cp /data/files /???


Nothing I try seems to work... Do you have any pointers on this??

Thanks...

I dug up the following at http://www.tuxfiles.org/linuxhelp/cli.html

"CLI for noobies"

After you have successfully done
Code:
#  cdrwtool -d /dev/hdc -q

you need to do:
Code:
# mkudffs /dev/pktcdvd/dvdwri

(cdrwi in your case I think)
then you should be able to do
Code:

Cintra...

Thank you for the the information you have provided and the suggested link. I finally have packet writing functioning without errors!

I appreciate the time you have taken to help me with this...

Yea I have the same here using LG Super Multi on 2.6.11-r9 kernel with compiled packet writing.

I followed this thread and got it going seemingly ok for now, took approx 20 mins to copy 2.2GB. It copies a bit then stalls then writes a bit but it was successful.

Could do with an up to date howto. One thing, does packet writing interfere with normal k3b copying or do I have to include something else in fstab file other than /dev/pktcdvd/dvdrw?

Edit - Well just answered one question, k3b recognises the dvd writer as /dev/hdc which in my case is right. Don't seem to be problem in K3b.

hi
The packet writing seems ok still 15 mins to cp 1.8GB thats not bad. But has anyone got trouble with eject. This has been a problem with me even without packet writing. I have installed hal 0.4.8 and pmount 0.8 which automatically create mount points in fstab i.e

/dev/hdd /mnt/dvd udf,iso9660 noauto,users,ro 0 0
#/dev/cdroms/cdrom0 /mnt/dvd auto users,unhide,ro,noauto 0 0
#/dev/hdc /mnt/dvdrw udf users,noauto,dev,rw 0 0
#/dev/hdc /mnt/dvdro udf,iso9660 noauto,users,ro 0 0
/dev/pktcdvd/dvdrw /mnt/dvdrw udf users,noauto,noatime,rw 0 0
#/dev/sr0 /mnt/cdrw auto noauto,ro,users 0 0
#/dev/fd0 /mnt/floppy vfat noauto,users,rw,sync 0 0
#/dev/sdc1 /mnt/sdc1 auto noauto,users 0 0
#/dev/sdb1 /mnt/sdd1 auto noauto,users 0 0
# NOTE: The next line is critical for boot!
none /proc proc defaults 0 0
none /dev/shm tmpfs defaults 0 0
none /proc/bus/usb usbfs devfaults,devmode=0666 0 0
/dev/hdd /media/cdrom auto user,exec,noauto,managed 0 0
/dev/hdc /media/cdrecorder auto user,exec,noauto,managed 0 0
/dev/floppy/0 /media/floppy1 auto user,exec,noauto,managed 0 0

However this does not help with ejecting. Root can eject ok and I can mount/ unmount ok (except /dev/hdc takes a while to stop working after packet writing).
I have two drives one dvd writer (LG) and one ordinary dvd player, both are on same cable the writer is primary. Using eject 2.0.13-r1 linux 2.6.11-r11 kde 3.4.1

I would like to add my two cents. I had a problem formatting a cdrw. It used to work before, so I was quite fustrated to find if failed now. After playing around with cdrwtool and pktsetup and all those friends, I noticed that I could format on cdrw and not another. The only difference between the two is was that the one that failed had audio tracks already on it. So, my advice when formatting a cdrw that was used before, use cdrecord to blank it first :)
