This is just an information for thouse, whose also got the player hanging with the "Kernel Panic, unable to mount" error, that I've also got with my new shipped player and how I fixed it:

I opened the case and just plugged the secondrary IDE connector to the HD and everything worked fine!
BTW: I've got of the glue in _one_ piece... ;-)

Questions related to this:
-Is this a "proper" way, or should I completly replace the cable?

-For a cable replacing, will an normaly notebook IDE cable do, or hould I "orde"r one from RIO support?
