Hello there!! It is my first time to use an AMD platform and I am impressed by its high performance while comparing with Intel platform with similar price. However, there is something wrong with my PC. When I wake up my PC from sleeping mode, my 10T HDD will disappear. And these are my disk management site before and after its sleeping mode:
As you can see, the disk 2, or the 10T HDD disappears. I have asked some of my friends about this problem, and they said it is the common side effect for an AMD platform after wake it up. Also, I have asked Microsoft about it, their engineer said maybe my HDD have some problems. I have no idea about how to solve it. My system information is attached below. I am fully appreciate for any assistance.
First of all, I have to appreciate for your assistance. Yesterday I have use SeaTools and HDTUNE to diagnostic my Toshiba HDD, and those results show that my Hard disk has no problem. Therefore I thought the problem maybe occured by SATA cable or SATA power cable. I changed SATA cable from SATA 6 to SATA 4 and changed its power cable and then tried to sleep my PC again, I woke it up shortly, my HDD disk won't disappear!! This tricky problem maybe solved until now, and tonight I will try to keep my PC sleeping for a long time, and I hope the problem will be solved entirely.
