Hi! I had a lot of problem with packet writing but I got to solve a lot of them. Unfortunately I have now one that I can't solve yet. I have a Slackware 10.1 and I use a vanilla kernel compiled by myself 2.6.13.2 When I gave the command pktsetup pktcdvd0 /dev/hdc I received the following error "ctl open: Not a directory" I tried to use the following rules in 10-udev.rules but I don't get any results. KERNEL=="pktcdvd", NAME="pktcdvd/control", GROUP="users", MODE="0660" KERNEL=="pktcdvd[0-9]*", NAME="pktcdvd/pktcdvd%n", GROUP="users", MODE="0660" So I solved the problem putting the following lines in /etc/rc.d/rc.local rm /dev/pktcdvd mkdir /dev/pktcdvd Now there are no problems with "pktsetup pktcdvd0 /dev/hdc" (I'm writing this if I had committed some mistakes in this way) Unfortunately now I can't mount any cd-rw formatted with "cdrwtool -d /dev/hdc -q". With "mount -t udf -o rw,noatime /dev/pktcdvd/pktcdvd /mnt/udf/" I have "mount: wrong fs type, bad option, bad superblock on /dev/pktcdvd/ciao, missing codepage or other error In some cases useful info is found in syslog - try dmesg | tail or so" Instead I can mount a cd-rw formatted with InCd for Windows but then, if I want copy a file on the cd the led of dvd-writer starts and not stop to be on (I've waited for an hour!!!). The device results to be always busy and so I can't umount the device. when I use the reset button (the computer doesn't shutdown normally) and I reboot the system there aren't on the cd the files I've tried to copy. I have a similar situation with a dvd+rw. I can format it with the dvdtools and I can mount the device but when I try to copy a file on it the led of the dvdwriter starts to be always on. I can't umount the device but when I shutdown the computer (with the dvd it shutdowns normally) and i rebbot it I can see on the disc the files I've copied on it. Sorry for my long e-mail. I hope anyone can help me since I would need the packet writing. Bye Francesco
