Re: грешка при cdrecord -scanbus
Звучи ми като незареден ide-scsi модул?
Виж си /etc/lilo.conf дали имаш нещо подобно:
mage = /boot/vmlinuz
root = /dev/hda3
append = "hdc=ide-scsi"
label = Recorder
read-only
На кой IDE канал е закачена печката - hdc (secondary-master) може да е и hdd ако е secondary-slave
Ако си правил промени в /etc/lilo.conf пусна ли lilo след това?

Реших проблема :-)
Ето как изглежда файла ми lilo.conf
boot = /dev/hda
prompt
timeout = 50
# Normal VGA console
vga = normal
# End LILO global section
# Linux bootable partition config begins
image = /boot/vmlinuz
root = /dev/hda7
append = "hdc=ide-scsi"
label = Linux
read-only # Non-UMSDOS filesystems should be mounted read-only for checking
# Linux bootable partition config ends
# DOS bootable partition config begins
other = /dev/hda1
label = DOS
table = /dev/hda
# DOS bootable partition config ends
И ето какво писах:

Re: грешка при cdrecord -scanbus
:-)
Предполагам причината е, че трябва да се зареди преди изпълнението на инициализиращите скриптове. Ако се зареди по-късно, диска продължава да е устройство /dev/hdc. Ако преди инициализацията заредиш модула, тогава се емулира scsi адаптер и устройството става /dev/scdX и carecord -scanbus го открива
Сигурно има някакъв начин да се излъже, но не знам как.

Re: Стана ми ясно (или само така си мисля)
През цялото време си е било написано във файла /etc/rc.d/rc.modules:
# *** THIS IS STILL LOADED BY DEFAULT ***
# SCSI emulation support. This will provide SCSI host adapter emulation
# for IDE ATAPI devices, and will allow you to use a SCSI device driver
# instead of a native ATAPI driver. This is useful if you have an ATAPI
# device for which no native driver has been written (for example, an ATAPI
# PD-CD or CD-RW drive); you can then use this emulation together with an
# appropriate SCSI device driver. Note that this option does NOT allow you
# to attach SCSI devices to a box that doesn't have a SCSI host adapter
# installed. Also, you'll need to exclude your CD-RW from being grabbed by
# the normal ATAPI driver by passing a flag to the kernel at boot time.
# If you're using LILO, add this: append="hdc=ide-scsi"
# Replace "hdc" with the appropriate device name.
/sbin/modprobe ide-scsi
Даже бях прегледал файла от горе до долу и бях сложил коментар на тези модули, които ми се струваха ненужни. Даже сложих коментар на /sbin/modprobe ide-scsi - груба грешка
Патрик ми го е написал с ГОЛЕМИ БУКВИ и даже е сложил мако звездички - *** THIS IS STILL LOADED BY DEFAULT *** и е обяснил, че трябва да се човърка в lilo.conf ама кой да чете...
Това с големите букви горе-долу му хващам смисъла, но не мога да го преведа буквално - не ми е ясно значението на думата STILL

Re: стана ми още по-ясно :-)
Когато се опитах да монтирам диск в печката ми излезе това:
valentin@machine:/dev$ mount /mnt/cdrw/
mount: wrong fs type, bad option, bad superblock on /dev/cdrw,
or too many mounted file systems
(could this be the IDE device where you in fact use
ide-scsi so that sr0 or sda or so is needed?)
Който е писал програмата за монтиране заслужава медал!
Това направо си е изкуствен интелект...
Послушах програмата и промених връзката /dev/cdrw от /dev/hdc на /dev/sr0:
root@machine:/dev# ls cdrw -la
lrwxrwxrwx 1 root root 3 2003-10-11 16:29 cdrw -> hdc
root@machine:/dev# rm cdrw
root@machine:/dev# ln -s sr0 cdrw
И пробвах да монтирам пак - и стана :-)
Пробвам cdrecord -scanbus

Re: грешка при cdrecord -scanbus
Pri mene stana i be3 modificirane na lilo.conf ama triabvashe da napravia rmmod ide-cd && modprobe ide-scsi (Debian 3.0r1), ne 3nam na Slack kak sa konfigurirani kernelite (ako pol3vash starndartnite).
Ako niakoj den kompilirash kernel probvaj da vklu4ish ide-scsi i ide-cd inline v kernela i kaji dali raboti i dali iska append= v lilo.con ;-)
