Rumboogy Posted July 29, 2013 Share Posted July 29, 2013 I have a Force GT (90GB, FW ver. 5.06B) that is installed in a "early 2011" MacBook Pro 13". It fails to boot about every 7th time. What happens is I get the grey Apple logo and the spinning clock and then the Apple logo changes to a circle with slash (like a do not enter sign). I have tried these combinations: - Force GT all by itself in HDD bay - Force GT in HDD bay and Hitachi OEM drive in optical bay - Force GT in optical bay and Hitachi OEM drive in HDD bay I also tried using cloned versions of OS X and a fresh install. Also did SMC and PRAM resets. Nothing works. This Force GT is just not reliable on boot. But once booted (if it does succeed) then there are no more problems. So this is purely a boot time issue. What do y’all think? Link to comment Share on other sites More sharing options...
