After upgraded, the Windows startup becomes to slower and show the "SATA IO time out" error every time and I found your forums have the same problem. May I know how to deal this trouble you made, it has been a long time and upgraded several times when it had happened which every time I supposed your technician can solve as soon as possible?Guys, could you please generate the problem report right after the issue reproducing? Please check this KB article for more info and reply us back with the report ID.
