Hello Kevin,
thank you very much for replying. I will provide as much info as possible. The only problem I have is that the pc is active in work use in a "mission critical" setup now and I am not allowed to do changes (it's my father's pc). I had this conversation already with Fred from intel mainboard email support. I also sent sysrem reports. When Fred replied I already used RST 13.5 from french site station-drivers. I asked if it's fine with intel that I use this version and most importantly that I obtain the driver from that site. He did not say that I'm not allowed. Only that it's beta version. I hope it's fine with everybody at intel that I use RST 13.5 from that site. I will explain why I don't use 13.1 instead of 13.2 below. The DXDiag report I attached here is with RST 13.5 installed. Here are the infos that come to mind. Please ask for specific infos you might need and I have not named:

Now the issue as completely as I can tell:
- tested RST versions -
13.5.0.1056 perfectly stable
13.2.4.1000 30sec-time-blocks of Windows Explorer and USB-storage read/write operation freezes, total system breakdowns with IMGBurn tool
13.1.0.1058 no issues except for a possible short and harmless but strange empty ODD disc cursor screen flashing after boot (could never reproduce it again)
12.9.0.1001 perfectly stable
12.8.0.1016 perfectly stable
- 13.2 freezes and reproducing one -
After cold boot ir restart empty ODD "clicks" (clicking noise) every 3 seconds for about 30 seconds. Sometimes for another 30 seconds. Widows Explorer doesn't update while clicking. When a SanDisk USB3.0 Cruzer Ultra USB-stick is connected and diskpart is run, opening of diskpart and commands like clean, create partition primary, active, format quick and exiting diskpart hang while clicking. No damage is done to data or hardware by the issue. After clicking operation simply continues and everything is good. Reproducing the issue: Install RST 13.2 connect the USB stick and start diskpart and the commands described. Clicking and freezes will start at first or second tries to provoke it with diskpart commands.
