My PC have Gigabyte GAEP35C-DS3R Motherboard update BIOS
Corsair XMS 2 4 GB ( 2GB each)
Intel Quad 9300
Corsair TX 750 Power supply
EVGA GTX 9800 Video Card
2 Seagate HD with one of each Window XP, Vista 32 bit : (1) 500GB, (1) 1TB
2 Western Digital HD with one is Vista 64bit, one is Window 7
1)1TB and (1) 500 GB
No RAIDS on four HD
When I use either Window. I pull the power cable to attach other HD to start open which one I use. But all other cables still attach to motherboard are leave alone only one power cable. It had been work as well until I installed new Window 7 I noticed that one is problem with stall or freeze than other Windows. I had not see any problem with old Windows. I wonder if any HD diagnosis Seagate software will tell if this HD is slow? I have one didn't said if this one is slow. But I like Western digital software diagnosis work better. Maybe Seagate is defect? How I know this?
