Bingo, right as usual! Apparently I wiped the USB stick. I ran fdisk and mk2fs -j again (do I want journaling?) and reinstalled Damn Small Linux on the stick. For some reason the laptop tell me "missing operating system" when I try to boot from the stick now. I need to test it on other systems. > Incidentally, if you want to use dd, adding bs=4096 speeds it up quite > significantly. Thanks, will do: dd if=/dev/zero of=/dev/sda bs=4096 - Grant
