As i stressed too much already, the growisofs bug should be fixed in any case. If it is possible to let K3b use cdrecord for DVD and BD, then i would apply for enabling my program cdrskin, too. (Actually i think it would be easier to emulate growisofs capabilities by cdrskin than by cdrecord.) k3b does not need the CLI interface from growisofs and happily works with the CLI from cdrecord.

Thomas Schmitt scdbac...@gmx.net wrote: Hi, Okay, then, is your patch necessary when using this command: growisofs -dvd-compat -Z /dev/sr0=image.iso with a DVD? No. I do not know about any growisofs flaws with DVD. As mentioned before: growisofs does not correctly follow the SCSI standard and as a result, it does not work with all drives. In addition, growisofs does not know about firmware bugs and this also causes problems with some drives. It's source is compiled using the C++ compiler, but inside it looks like assembly. If the original author does no longer support it, more than small changes are not worth being done. I would be interested if anyone misses specific features from growisofs in cdrecord.

If you wanted to implement a fingerprint swiper and retina scanner, easiest would to be fit all that plumbing into PAM and tell the system to use it. PAM ships out of the box using shadow as the default way to auth users (i.e. by password). pambase is what implements this default method. pam (the full thing) implements the plumbing you need for everything else. shadow and pam are renowned for causing blockers that can't be automagically resolved, it's because they slot in at very low levels. not liking eachother.

[gentoo-user] I've got an ARM SoC board - now what dir's to put on the SSD
Hi all, I've bought one of the ARM based Cubieboards which I intend to use as a media server. I've got Gentoo running on it but would now like to push system stuff across from the SD card to the SSD drive - you can't boot from the actual SSD you need to do that from an SD card. This way it should be a bit quicker and I won't run out of SD card space as the system is updated. Can anyone point me to a webpage that has recommendations or has actual experience as to what I can shift across? I'm guessing /usr/portage/* would be the one to go across? Regards, Andrew

You won't find much in the way of real recommendations on this, as it's all subject to how you want it to work best. What you will find out there is much opinion about what is good, I just offered you mine. A good starting point might be to look at projects like openelec for Raspberry Pi and see how they do it, the use-case looks similar to yours [1] IIRC this is the new portage default anyway unless you change it.

I was able to correct them (force reallocation) using hdparm... So it should be fixed, and I'm reading that this is normal with newer drives and don't worry about it, but I'm still coming from the time when 1 bad sector = red alert, replace the drive ASAP. I guess I will need to monitor and see if it gets worse. Way back when in the bad old days of drives measured in 100s of megs, you'd get a few bad sectors now and then, and would have to mark them as faulty. This didn't bother us then much Nowadays we have drives that are 8,000 bigger than that so all other things being equal we'd expect sectors to fail 8,000 time more (more being a very fuzzy concept, and I know full well I'm using it loosely :-) ) Our drives nowadays also have smart firmware, something we had to introduce when CHS no longer cut it, this lead to sector failures being somewhat invisible leaving us with the happy delusion that drives were vastly reliable etc etc etc. But you know all this. A mere few dozen failures in the first 100 hours is a failure rate of (Alan whips out the trust sci calculator) 4.8E-6%. Pretty damn spectacular if you ask me and WELL within probabilities. There is likely nothing wrong with your drives. If they are faulty, it's highly likely a systemic manufacturing fault of the mechanicals (servo systems, motor bearing etc) You do realize that modern hard drives have for the longest time been up there in the Top X list of Most Reliable Devices Made By Mankind Ever? An update: the Seagate drives have both continued to spit more unrecoverable errors and find more and more bad sectors. Including some end-to-end errors indicated as critical FAILING NOW status in SMART. From what I have read that error means the drive's internal cache did not match the data written to disk, which seems like a serious flaw. The threshold is 1 which means if it happens at all, the drive should be replaced. It has happened half a dozen times on each disk so far (but not at the exact same time, so I don't think it is a host controller problem -- and other disks on the same controller and cable have had no issues). They have also been disconnecting and resetting randomly, sometimes requiring me to pull the drive and reinsert it into the enclosure to make it reappear. It happens even after I disabled APM, so I know it isn't a spin-down/idle timeout thing. Temperatures are actually very good (low 30's) so they are not overheating. I think I will try to trade them in to Seagate for a new pair under warranty replacement. And then probably try to sell the replacements and be rid of them. Meanwhile, during that experiment, I bought 2 brand new Western Digital Red 3TB drives last week. No problems in SMART testing or creating LVM/RAID/Filesystems. I have now been running the destructive write/read badblocks tests for 24+ hours and they have been perfect so far, exactly 0 errors. They are more expensive (3TB for the same price as the 4TB seagate) and slightly slower read/write speed (150MB/sec peak vs 170MB/sec peak), but I value reliability over all other factors. These Seagate drives must have some kind of manufacturing defect, or perhaps were damaged in shipping... UPS have been known to treat packages like a football!
