I tried installing cd version of 7.0.3 on two Corsair Flash Voyager 8gb sticks and get the same error as Karibu: lseek:invalid arguement, etc. If I open gparted in the livecd after the failed installation, it does not detect the usb stick. If I reboot into a different linux distro, gparted detects the usb stick. I have successfully installed another linux distro on one of the usb sticks, so that indicates that the problem is not with the stick (?).
Any resolution to this problem?
Never able to install 7.0.3 on my flash drive, I downloaded 7.0.4CD release with anticipation that whatever had prevented installation was corrected. I started the flash installer, reformatted the flash drive, watched the installation proceed further than it had with 7.0.3, but then a new error message:
cp:reading 'KNOPPIX/KNOPPIX': input/output error
cp:failed to extend '/tmp/flash-knoppix.3213.tmpmount/KNOPPIX/KNOPPIX': input/output error
This happened on two different flash drives. I was able to install 6.7.1 on a flash drive, but not 7.0.3 or 7.0.4.
Can anyone help?
Have you been able to install another current Debian-family distro on the stick(s)? As is documented earlier in this thread, there are/have been problems with some library versions. Your 7.0.3 vs 7.0.4 experiences may indicate that this has been worked on, but is still not fixed.
Capricorny, thank you for your reply. I have not tried another Debian distro, but will do so today. With Knoppix I tried "Install Knoppix to flash disk" which I assumed was a special flash drive installer. Maybe that is not true and it simply targets a usb drive vs HD?
I did not note that I previously installed 6.7.1 successfully with the flash installer. Also, I was able to install 7.0.4 using Unetbootin, though it runs slower than the 6.7.1 installation. Would that be Unetbootin or a difference between 6.7.1 and 7.0.4?
I think the "flash install" without formatting actually is just writing a boot record plus copying the ordinary set of Knoppix system files. Eventuallly creating knoppix-data.img.
The libraries used in unetbootin are probably different from current standard Debian, so you could therefore use them for writing to the stick. When Knoppix boots, but runs slowly, that may indicate I/O problems, again from the current Debian utilities being used. So my guess is that you observe a 6.7.1/7.0.4-difference, unetbootin may not be involved at all.
I tried installing Debian 6 to flash drive and during partitioning procedure had this message: Error informing the kernel about modification to partition /dev/sdd2 -- Device or resource busy. This means Linux won't know about any changes you made to /dev/sdd2 until you reboot -- so you shouldn't mount it or use it in any way before rebooting.Quote:

Re slowness of 7.0.4 vs 6.7.1, seems like it might be CPU usage issue.
CPU usage upon device handling reflects the software runnig, be it kernel modules, libraries or application code. And my guess is that if you do something that ONLY engages kernel modules, like initial booting, you will seldom have any slowdown with newer kernel modules.Quote:

That is, unless there is an aggressive cache-writing/reading policy in place that effectively circumvents the Linux kernel's RAM-caching. In that case, we might se a double effect, both direct CPU usage and indirect through inefficient reading/writing. USB handling has traditionally tended to be rather CPU-intensive in any case.Quote:

Re my inability to use the flash installer to install 7.0.4 to a usb stick, I will go back to using 6.7.1 and hope the installation problem is solved by the next Knoppix release.
