I tried using the windows experience rating app today and got an interesting result. I received an error: 'Could not measure storage performance. Failed to properly assess the disk. The parameter is incorrect.' I checked winsat log for the errors and there was only one 'winsat\processwinsaterror.cpp:0095: ERROR: tried to read resource strings, unknown exception occurred' I thought I would restart and try again, but it hung at restart so I checked the cmos setup an noticed that my hard drive is listed as the third drive and my cd/dvd is fourth drive listed. They were previously Listed as one and two respectively. I am unable to change it back and I am hoping that it will be okay. Has anyone else had this problem?
