#21 formatting !



I got this HP CDwriter+ 8290 rev 1.3 C on my woody PC.
Kernel 2.4.18 - udftools 1.0.0B2
Patched the kernel with the packet-2.4.18.patch.bz2

loaded modules :

cdrom 26944 0 [pktcdvd sr_mod]
scsi_mod 49564 3 [sg ide-scsi sr_mod]

tried also loading the udf.o module :module loads ok, I
get the same errors as below.

then tried:
[Sat Jun 8][21:47:53]root@number1:udf# cdrwtool -d
/dev/scd1 -q -t4 -b full -w mode1
using device /dev/scd1
setting speed to 4
full blank

and :

[Sat Jun 8][21:50:53]root@number1:udf# pktsetup
/dev/pktcdvd1 /dev/scd1
pktcdvd: writer sr1 succesfully registered.

and when I :
[Sat Jun 8][21:51:00]root@number1:udf# mount
/dev/pktcdvd1 /mnt/udf

/dev/pktcdvd1: inserted media size is CD-RW
/dev/pktcdvd1: detected zero packet size !
/dev/pktcdvd1: unknown data mode
/dev/pktcdvd1: pktcdvd1 failed probe
mount: /dev/pktcdvd1: can't read superblock

I kind off understand why I get the last error ; cdrw
is not formatted I think. I think I'm missing something
with the formatting.
Could it be my CDwriter is not supported?

I would appreciate some help ;-)!

    I don't see where you actually used cdrwtool to format the
    CD. I'm using much the same setup as you (aside from
    hardware details), and it works fine for me with either
    standard-length (74 minute) CDRWs or the mini-disk size, but
    fails with 80 disks. See the item I filed above (probably
    should have gone to the bugs list, oh well, there don't seem
    to be any developers anywhere around here).

    Also, Peter says you should use the latest packet patch even
    though it's labeled as 2.4.19-pre4. I haven't seen anything
    that was different between them, but aside from one rejected
    hunk (in the Sparc architecture, so I don't care <smile>) it
    applies and compiles just fine.

    you were right : you didn't see any formatting (as I also
    did not see any) ;-).
    The formatting with "cdrw -d/dev/scd1 -q" (and different
    variants I tried) just failed/quit/stopped every time
    without error.
    I then tried it with Easy CD Creator : no probs formatting.
    Tried to read AND write under linux and bingo : it works.

    Now I'm trying another CDRW : it seems to work :

    [Mon Jun 10][20:49:50]root@number1:dewaele# cdrwtool -d
    /dev/scd1 -q
    using device /dev/scd1
    1312KB internal buffer
    setting write speed to 12x
    Settings for /dev/scd1:
    Fixed packets, size 32
    Mode-2 disc

    I'm going to do a quick setup of /dev/scd1. 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
    ENTER to continue.

    Initiating quick disc blank
    Disc capacity is 275616 blocks (551232KB/538MB)

    Both CDRW were 700 MB - 80 Min !
