[SOLVED] kernel 2.6 and ide-scsi

[jerryvb]

Does anybody know if the broken ide-scsi issue has been fixed in the 2.6 kernel series? I am currently running 2.6.10 on Slackware 10.1 and ide-scsi is not working. From what I've been able to find out on the web, it still isn't fixed, but I was just wondering if anybody knew for sure.

Thanks

I don't think it will ever be fixed. We burn our cd's with /dev/hdc or whatever now.

2.6 was never broken, it used a different format. Instead of

cdrecord -v -force -eject dev=0,0,0 /isos/damnsmall-0.4.4.iso

it uses

cdrecord -v -force -eject dev=/dev/hdc /isos/damnsmall-0.4.4.iso

P.S. ide-scsi does not exist anymore, it is all done in the kernel now.

Aha, okay. So how do I get my kernel to see my LiteOn cd writer at hdd? My cd writer is connected to ide channel 1 as a slave. Here's my ide setup:

ide 0,0 = 80GB hard drive
ide 0,1 = 80GB hard drive
ide 1,0 = cd/dvd drive
ide 1,1 = cd writer

I checked /dev and I don't have an hdd device. Can I create one?

I just recently upgraded the kernel from 2.4.29 to 2.6.10. With 2.4.29 I had an hdd device and cd burning with k3b worked fine.

I would go beck to 2.4.29, but I need the 2.6 kernel for the new motherboard that I just recently got.

make sure you don't have hdd=ide-scsi in grub.conf or lilo.conf, then post back with the output from:

cdrecord -scanbus dev=ATAPI

mine gives this:

Thanks je_fro. I already found this:

http://www.linuxsa.org.au/pipermail/linuxsa/2004-March/066290.html

I did:
1) in lilo.conf replaced hdd=ide-scsi with hdd=ide-cd
2) reran lilo
3) rebooted
4) ran cdrecord dev=ATA -scanbus and got this:

4) Brought up k3b and now it recognized hdd, the LiteOn cdrw drive
5) burnt a few files to a cd-rw disc in tao mode

The burning process seemed to be successful. At least k3b said it was. But, now I cannot get the newly burned cdrw disc to mount. I have added this line in fstab:

/dev/hdd /mnt/cdrw iso9660 noauto/owner/users/ro/exec 0 0

So, now what's wrong? I cannot get the newly burnt cdrw disc to mount, even as root???

When I try to mount hdd I get this:

bash-3.00# mount /dev/hdd
mount: block device /dev/hdd is write-protected, mounting read-only
mount: wrong fs type, bad option, bad superblock on /dev/hdd,
missing codepage or other error
In some cases useful info is found in syslog - try
dmesg | tail or so

bash-3.00#


Thanks

[jerryvb]

Okay, my bad. If I do:

#mount /dev/hdd /mnt/cdrw

it mounts the newly burnt cdrw disc just fine.

Thanks for your help je_fro!!!

Hope this helps someone else.
