Re: SATA+ IDE DVD-Writer crash, and missing /dev/fd0
[please include my email address in any replies]
Hi,
Thanks for your help, its working, read on for the details and one final
question.
testing, and unstable both have the same kernel in "stable" which am
already running:
http://packages.debian.org/unstable/base/kernel-image-2.6-k7
would a newer kernel use something other than ide-scsi for SATA drive
access? I am not sure how my root would be mountable if I remove
ide-scsi from initrd, or if etch/sid remove ide-scsi from their initrd.
SATA never used ide-scsi.
ok, I will try and remove it. initrd.img-2.6.8-2-k7 contains:
# cat loadmodules
modprobe -k vesafb > /dev/null 2>&1
modprobe -k fbcon 2> /dev/null
modprobe -k unix 2> /dev/null
modprobe -k sata_via
modprobe -k sg
modprobe -k sd_mod
modprobe -k ide-scsi
modprobe -k sr_mod
What is the -k mode? This is not listed on any man page. or is the
initrd modprobe a different program?
are sg, sd_mod and sr_mod not also for scsi? What do they do in
particular please? I see details of sr_mod and sg being used for "cdrom"
when booting up, whereas sd_mod is used for "disc".
This is how I mounted it, but I could not write to it, it said the
cramfs file was read-only. Is there a doc on how I can modify the initrd?
I decided just to copy the files out, and make a new cramfs archive.
# mount -o loop,rw initrd.img-2.6.8-2-k7 i
# cp -dpR * ~/initrd/
cp: will not create hard link `/root/initrd/devfs' to directory
`/root/initrd/dev2'
cp: will not create hard link `/root/initrd/keyscripts' to directory
`/root/initrd/dev2'
cp: will not create hard link `/root/initrd/mnt' to directory
`/root/initrd/dev2'
cp: will not create hard link `/root/initrd/proc' to directory
`/root/initrd/dev2'
cp: will not create hard link `/root/initrd/sys' to directory
`/root/initrd/dev2'
cp: will not create hard link `/root/initrd/tmp' to directory
`/root/initrd/dev2'
cp: will not create hard link `/root/initrd/var' to directory
`/root/initrd/dev2'
I dont see what the problem is, there is no link or hardlink in the
package, and why is it compared with dev2?
These are what I need, and it appears this cp has lost some of them now:
bin dev devfs keyscripts linuxrc loadmodules proc script
sys usr
bin2 dev2 etc lib linuxrc.conf mnt sbin scripts
tmp var
# mkdir devfs keyscripts mnt proc sys tmp var
I removed sr_mod and ide_scsi from loadmodules
#cd ..
# mkcramfs initrd initrd.img-2.6.8-2-k7_no_ide_scsi_2
ok, that worked. I now have /dev/hda and can read CD-ROMs and DVD-ROMs
# cdrecord dev=ATA: -scanbus

Is there a fix which will work as a normal user?
I used growisofs and that burned fine! :)
btw, is there a way I can burn in "verified" mode? I would like the
program to read back each sector at the end and check it matches what
was burnt etc.
Kind regards
