Yes, this is a somewhat known problem, I believe.  We really don't support
non-512K media at the moment (at least not the last I heard).  There were
3 proposed solutions in the works, but the development was slowed by the
death of the developer.  I believe someone else has picked up where he
left off, but not with quite the fervor.

I hope this clears things up a bit.

Later.
