Xbox kicks me out of installed game then loses memory until re-boot
Hi I've had my 250gb Xbox for about a year and no problems so far until last week...I'll be playing CoD:MW2 or GoW2 (both of which are installed) and whilst playing online the game will crash taking me back to the dashboard, game window in 'My Xbox' will
state 'Opening' and console has a flashing green light in centre of main button, I scroll along 'My Xbox' and my game library disappears and when I scroll further along to 'System Settings' and select 'Memory' I'm told 'No storage devices found.' Of my 250gb
memory I have 162gb free so it doesn't seem to be a memory space issue, disk based games are installed so are only inserted for verification purposes, I have an extended warranty package but just wondered if anyone else had experienced this issue a new a quick
fix? Any help/information appreciated.
