I'm trying to boot from an external USB drive with my wl500g (1.9.2.7-9) but the ext3 partition I made with the aid of another Linux system is not mountable. The log mentions an incorrect inode size (256). So I tried to format it using a telnet console on the wl500g. But after a few sectors the format is terminated. This happened with 2 different USB disks. One of them is a Lacie 500 GB disk.
