Hi I'm having a lot of trouble with a compaq mini 702ea. It initially came up with a hdd failure so replaced the hdd, after a day came up hdd bad again. I then replace the small orange cable which made no difference. I tried both faulty and new hdd in USB case on another machine and formatted them. When I try to load windows 7 via USB cd drive the OS can see the hdd but bios still does not, I've reset bios to factory default with no change. I have now replaced the motherboard and am still getting the same issue. I tried to put old hdd in with new m/b and the bios can see it but it says that it's faulty and to replace it. Can anyone please help I don't no what else to do?
