the good idea, here is to use the usb device name (versus /dev/sdx one), so much less risk to mix it with the main disk name. I have one archive usb 4Tb driven but it's easy to unplug it during the process.
using usb hubs is not a good idea, there are shared bandwith and often probably collisions of sort of, because the write can be incredibly slow, or device not working at all.
finally I did the job with a hub. I have a 7 ports powered usb ub. I could only plug 6 openSUSE usb flash devices (a bit too thick for the 7th). Using dd bs=4096 if=/data/telechargements/download/isos/openSUSE-13.1-DVD-x86_64.iso of=/dev/disk/by-id/usb-General_USB_Flash_Disk_05311100000000A8-0\:0 & I could write 6 device at the same time, in approx 20 mn, including typing the command. Using tab completion is very usefull. The device name seems to be this, the real device number, so no one is the same as the other. one needs to *not* use the "part1" part (two choices, with and without). It's pretty obvious, but the iso have to be written on the disk, not the first partition. I sticked on the device a small round blue sticker with written "34" to remember what is on it :-) I only wrote 12 of them, next big meeting is mid November, and I expect to use factory then (or 13.2 if available in time). Factory installs very well. thanks, everybody :-) jdd -- http://www.dodin.org -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
