Sure, what additional information can I give? I can do it, I just want
to try to minimize the damage :)

So:

1) I will try without -rt

2) I'm not sure if I'll get this error if the drive isn't mounted. If
I can then I will just stop it from mounting and do a bisect.

(please add more here that you need or want)
