I have just bough a brand new WD MyBookWorld 1TB. It's the single disk edition and it has "firmware" 22.214.171.124 installed, which I presume basically means kernel 126.96.36.199
I have setup gcc and nfs and the drive works as I had hoped. However, I was rather looking forward to encrypting everything on it as in the tutorial on the main page and also at Martin Hinner's site.
After unmounting /shares/internal and copy and pasting from martin's site:
echo 0 `cat /sys/block/sda/sda4/size ` ox-crypt 12345678901234567890123456789012 12345678901234567890123456789012 0 /dev/sda4 0 |/usr/sbin/dmsetup create dmsda4
device-mapper: reload ioctl failed: Invalid argument Command failed
I have had a good hunt around the disk and cannot find anything called 'ox-crypt'. I also could not find this in the backup version of / which is used in the tutorial to enable gcc.
This leads me to suspect that 'ox-crypt' is a kernel module which WDC have in their infinite wisdom decided to uncheck when they compiled the kernel.
Does anybody know if this is the case? and if so do you know of a kernel patch for kernel 188.8.131.52 which would allow for full partition encryption?
