Finally got my replacement controller from MS today and the random disconnecting issue appears to be gone, which is a relief as I was worried it might have been an issue with the console.
The new controller doesn't seem to switch itself off after x minutes of inactivity, the old one use to power off after 2-3 minutes inactivity, is this something they changed in a recent update?
I actually prefer it not switching itself off, but I couldn't find any setting for it.
So powered up the Xbox today and started installing some games from the Store and I've noticed the hard drive makes a bit of noise.
Now I've heard that some people are having problems but the level of noise is not at all the same noise level.
It sounds like normal read / write access but I want to check if this is OK?
I can hear the hard drive in mine while it's busy, but it can only really be heard if the room is quiet. I can't recall the loudness of it varying with mine though, I think it's consistent.
