before you all post the hate comments on PC, let me be clear that along with the pc i built, i also bought a MacBook Air 13" base. so i built a PC for the shear purpose of being university-friendly (since all my uni software require pc). the specs are as follows: CPU: Intel core i7 3770K RAM: 16GB at 1600 primary boot: 240GB intel SSD -> OS and all programs secondary HDD: Segate 1TB -> where all my files are stored motherboard: ASUS P8 Z77-vlk graphics: intel HD 4000 i am not a huge tech guru so i seek this help. the pc is blazing fast but when i am not accessing any files or doing any work on a file (saved on the 2nd HDD), the 2nd drive goes to sleep. it irritates me every time i access a file because the HDD clicks on and there is a lag of about 2 seconds before the computer starts functioning again. how do i circumnavigate this problem? is it because my power supply is not providing enough juice that it goes to sleep? or is it a problem with the HDD itself? the help would be much appreciated.
