Full details don't seem to have appeared yet, but the reports I've seen seem to say that out of the three C&C computers (one live, two backups) at least 2 have experienced hard-drive failures/problems. One has been pulled and replaced with a spare and will be returned to Earth on the shuttle, the other has apparently had a software tweak to limit drive usage. Check the mission updates on sci.space.news and also the coverage on The Register at http://www.theregister.co.uk/content/2/18526.html and http://www.theregister.co.uk/content/2/18540.html (the second report corrects the faulty assumptions of the first). -- David Gillon Process Control Team Eurofighter FCS Avionic Systems BAE SYSTEMS Avionics Rochester, Kent, UK
