After testing, scanning with all tutorials from your forum i can't fix my problems with HDD.
My 1TB WD disk constant goes to sleep. I don't understand why, coz other two HDD are ok. Is there some stuff with jumpers? Im not sure if this is sleeping problem, but when i open HDD, drive needs +/- 10 sec to establish.
How to fix this? and another problem, when hdd goes back to "sleep mode" almost all the time crash my PC (BSOD).
Like i said before, disk is tested with chkdsk C: /F /R and HDD diagnostic utility...
