Hello,
First, here are the infos you might need to help me:
-Asus ROG Maximus IV Intel P67 chipset
-HDD in question is Samsung M3 portable 500 GB HDD on USB 3.0 interface
-I am plugging the device directly into the motherboard's USB 3 port in the back I/O
-I tried different ports on the same PC but nothing gives; it runs at full sped on 3 other different PC's (60 MB/s and not 30 MB/s like I see on mine).
I need help concerning my SATA controller after I saw windows troubleshooter not being able to fix this on its own. It all started becasue of my external HDD that uses USB 3.0 actually running at USB 2 speeds. It has been doing that since I bought it so the issue has existed long before I started using that drive.
After running device troubleshooter it said it couldn't fix the issue and then I decided to go in device manager to see for myself what happened. When I got there, it said that one of my 2 AHCI SATA controller had the issue coded '10'. I have no idea what that means...
Also, is it safe to uninstall the driver for the controller? What are the consequences if I do so? What do you guys suggest I do?
A quick answer would be really appreciated as the slow speeds are killing me...
Thanks, Dunkan77
