Hi all, does anyone know what is wrong with this: dd if=/dev/zero of=/dummy.img bs=1024K count=10 losetup -e blowfish /dev/loop0 /dummy.img with password: FFFFFF (or any other password)? All I get is: 'ioctl: LOOP_SET_STATUS: Invalid argument' Thanks in advance, Fred ___________________________________________________________ Yahoo!
