I did notive in my PS3 box was a card with a 24hour call centre you can call for technical questions about the PS3, if I have no love from Sony will give them a call at the weekend and post what I find.

Ive also got a spare 160Gb 2.5sata drive here at the office that I was going to take home and do a clean prep on and see what I loose. The instructions are in the manual so I dont think there is any fear of damaging the thing. See what gets installed on a clean format and prep.

will post any results I get.
cheers
