Well, most of this has been discussed on Ann, so let me boil it down to some points:
There is allegedly code in Elbox's USB device which will nuke your disk RDB if it is tampered with. This is not proven.
The guy who allegedly found the anti-RDB code was probably trying to hack the usb.device to use a non-Elbox USB card. This is illegal.
If Elbox have indeed added the anti-RDB code intentionally, then they have broken the law and can be sued for data loss. Again, I stress that no absolute proof of the presence of the code has been found.
