I just inserted a ubuntu-8.04 LTS cd I burnt in that drive, and it was about 14 seconds till the led went out the last time and a what do we do with this new disk requester had popped up. That brought up good old konqui, in the single tree view mode. That brings up another question. I hear folks praising konquerer for its file manager abilities, but to me a file manager is a 2 pane operation ala mc. I always fall back to mc cuz it Just Works(TM), it can do lots of things krusader can't even think about doing. What the heck good is konquerer when an attempt to change directories in the left window throws away the right window? I fail to see how that can possibly be useful. I have not found a config option to make it a true, 2 pane file manager. So why do they call it that? unmounting that cd, and inserting an F7 install dvd, the recognition phase took about 20-21 seconds, but whatever pops up the what shall I do with this selector still hasn't 2 minutes later, so I mounted it by hand, and that took circa 10 seconds. So if, before k3b can verify the disk, it has to wait for that about 30 seconds to gain access to the file structure, or 20 seconds just for dd to be able to access the unmounted disk. The error/failure pops up about 2, maybe 3 seconds after it has pulled the disk back in, apparently unwilling to wait until the drive has accepted this 'new' media. All this BTW with kernel 2.6.26-rc6 doing the chores. Despite all the reports otherwise, I haven't been able to tie this non-working situation to a given kernel release. The last time I tried one of the fedora kernels to test something that someone was fussing about, I could not duplicate their problem. Normally, when yum installs a new kernel, it also does a very poor job of editing my grub.conf, over-writing my default choice, and messing with the numbering system I use there. So when I see yum put in a new kernel, the first thing I do is go fix my grub.conf again. Sort of a fetish I guess. :) >> Generally, if during the time that the drive led is still on after the >> disk has been pulled back in, then k3b, or anything else that wants to >> read it can sit by silently, or take a dump and abort the operation. k3b, >> or whatever util is doing this latter, and really does need to learn to >> wait. > >And why does it work with kernel 2.6.23.15-137.fc8? No idea as I don't have a kernel that old on this system. My historical kernels start with 2.6.24.4, and the oldest fedora is vmlinuz-2.6.24.5-85.fc8. If that 2.6.23.15-137.fc8 is the kernel you are running, that would have to date to the original spin of the F8 release, and to not have upgraded since just to stay ahead of security concerns alone seems very careless to me. >Why is the drive >ready to read with that kernel, but not with the newer ones?

These things are mechanical servo's, and there will be variations. As for specs, I don't have the money to purchase a copy of either the red book or the orange book. If it works, fine, if it doesn't, well I needed to go to town anyway didn't I? >-- >Fedora release 8 (Werewolf) - Linux 2.6.23.15-137.fc8 >loadavg: 1.11 1.21 0.94 -- Cheers, Gene "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
