I read this topic 100 times in these fourm and never can find a Reason why this happens or how to fix it. So it finally happend to me. I use a Raid Sata card.I uninstalled it took it out of my Computer Booted it it up, Shut it down reinstalled my card. Shut it down once again did all my 360 stuff turned the tower back on and bam there sat my 360 drive once again. Has anyone ever reinstalled Netframe when this happens? Wonder if that would work? :twisted:
