Hello to all. I burn in windows several cd and dvd, encrypted with crosscrypt filedisk, AES256 but i can't mount any in my fedora core 3. I always get an "ioctl: LOOP_SET_STATUS: Invalid argument" error. kernel version: (uname -a) Linux core3.mydomain 2.6.9-1.667 #1 Tue Nov 2 14:41:25 EST 2004 i686 i686 i386 GNU/Linux How i encrypt: filedisk /encrypt plain.iso crypt.iso /aes256:some.long.password.with.more.than.20.char How i try to setup the loopback device [root@core3 mnt]# losetup -e AES256 /dev/loop0 /dev/hdb Password: ioctl: LOOP_SET_STATUS: Invalid argument Feedback with dmesg: lp0: console ready FAT: invalid media value (0xc2) VFS: Can't find a valid FAT filesystem on dev hdb. loop: loaded (max 8 devices) I also check the kernel modules, and all is OK. I also install a new kernel, and re-compile with all loopback support enable What can i do? what I'm missing?
