finlay Posted February 16, 2004 Report Share Posted February 16, 2004 (edited) I have always had the line "append hdd=ide-scsi" in lilo.conf to enable my cdwriter. My devices were listed as /dev/hda1 etc as usual. I then added "hdc=ide-scsi" to my append line in order to make my dvd drive recognized by K3B and to my amazement df now lists all devices as part of scsi chain, as in: /dev/ide/host0/bus0/target0/lun0/part7 Kdiskfree shows the original (/dev/hda) type list followed by the scsi-type list. only the latter list has the graphic showing the amount of disk free. Can anyone explain this to me? I realize it makes no difference to my system, it's only a matter of nomenclature --- or is it? BTW I removed the hdc entry from append (and ran lilo of course) in an effort to get back to the original listing format - but no go. Still got the scsi-type listing. Please explain, someone!

Ixthusdan Posted February 16, 2004 Report Share Posted February 16, 2004 The ide devices are hda for primary master, hdb for primary slave, hdc for secondary master, and hdd for secondary slave. You have simply removed your secondary master, and none of this would explain why you are emulating scsi on partitions. So, would you post your /etc/fstab?

bvc Posted February 16, 2004 Report Share Posted February 16, 2004 This has been asked b4 and no one knew why the display changed. Maybe someone will this time. Quote Link to comment Share on other sites More sharing options...

You have simply removed your secondary master, and none of this would explain why you are emulating scsi on partitions. So, would you post your /etc/fstab? Yes, I understand about the convention of device listings. ( I didn't remove my secondary master - simply removed the reference from my append line in lilo so that it wouldn't be seen as a scsi device.) AFAICS the emulation is on devices, not partitions i.e. they refer to the devices which are mounted on partitions. I'm glad it's been seen before, bvc - I'm not alone :D For interest, though I don't see how it can help, here's my fstab: /dev/hda7 / reiserfs notail 1 1 /dev/hda6 /boot ext2 defaults 1 2 none /dev/pts devpts mode=0620 0 0 /dev/hdb5 /extra ext2 defaults 1 2 /dev/hda8 /home reiserfs notail 1 2 /dev/hdc /mnt/cdrom iso9660 unhide,user,noauto,ro 0 0 /dev/scd0 /mnt/cdrom2 iso9660 unhide,user,noauto,rw 0 0 /dev/fd0 /mnt/floppy auto noauto,user 0 0 /dev/hda1 /mnt/win_c vfat codepage=850,iocharset=iso8859-15,umask=0 0 0 /dev/hdb2 /mnt/win_d vfat codepage=850,iocharset=iso8859-15,umask=0,defaults 0 0 none /proc proc defaults 0 0 /dev/hda9 /usr reiserfs notail 1 2 /dev/hda10 /var reiserfs notail 1 2 /dev/hda5 swap swap defaults 0 0 Finlay Edited February 16, 2004 by finlay Quote Link to comment Share on other sites More sharing options...
Ixthusdan Posted February 16, 2004 Report Share Posted February 16, 2004 When I am home, I will post my fstab. I use scsi emulation for both cd devices so that k3b can make cd copies. (Nothing illegal, of course!) Turning off scsi emulation simply prevents k3b from using two devices. Is it a software program that is showing this? Perhaps the program is the error. I'll check it out when I get home. Quote Link to comment Share on other sites More sharing options...
chris z Posted February 16, 2004 Report Share Posted February 16, 2004 (edited) are you having a k3b burning cd's problem, or are you just curious about how storage devices are listed in Kontrol Center->information->storage devices? if it's the latter, they look like this, correct? if that's the case, it's normal & nothing to be concerned about. see this post & look for my reply about half way down the thread....... Weird Partition Names if it's a k3b burning problem, please post exactly what the problem is & we can take it from there.

Qchem Posted February 16, 2004 Report Share Posted February 16, 2004 Can I ask why you have your cd-rw mounted as rw, AFAIK this won't really do anything - or are you attempting to use some UDF packet writing. While I'm at it I'll also troll and suggest that your problems all stem from using reiserfs Quote Link to comment Share on other sites More sharing options...
aRTee Posted February 16, 2004 Report Share Posted February 16, 2004 Quick reply to the first posts: /dev/ide/host0/bus0/target0/lun0/part7 is not scsi, but plain ide. And has been for quite some time, /dev/hda7 was just a link, for backward compatibility and easier use. scsi emulation days are over soon, kernel 2.6 writes directly to any ide device; I already used it in k3b, it works great. Don't know yet if it uses less cpu, only burnt a cdrw which was at 12x, which doesn't show up on my cpu load... Quote Link to comment Share on other sites More sharing options...
bvc Posted February 16, 2004 Report Share Posted February 16, 2004 display is the issue, no? If someone that is 9.2 and up would post the output of df -h you'd see what finlay is referring to. I can't rt now. Quote Link to comment Share on other sites More sharing options...

finlay Posted February 16, 2004 Author Report Share Posted February 16, 2004 (edited) Just to be clear. It's not a problem with k3b, just the interesting way the devices are listed. aRtee seems to have provided the answer " /dev/ide/host0/bus0/target0/lun0/part7 is not scsi, but plain ide. And has been for quite some time, /dev/hda7 was just a link, for backward compatibility and easier use." Never knew that. As I said in my original post "I realize it makes no difference to my system, it's only a matter of nomenclature --- or is it?" So it is. End of story. However, the display in kdiskfree seems to have unneccessary redundancy, no? And it's a bit of a shock for those of us who've been used to /dev/hda1 and so on (since 1996 in my case) to find everything listed differently! :o Many thanks for all your replies.
