I have recently upgraded my motherboard/cpu/ram; I went from a MSI P7N/Q9450/4GB DDR2 Ballistix to a Gigabyte X58A-UD3R/i7 920/6GB DDR3 Patriot.
I am really not sure if this is related, but after getting this build done, I notice a slight click coming from one of my drives randomly, sometimes it's every few seconds and sometimes every few minutes but it keeps making this faint click. Maybe heads parking or something, I don't know.
I do not have older screenshots for all my drives unfortunately.
I have tried replacing sata cables for all drives and replacing power cables for all drives. Performance wise, I don't feel the hit, movies and music do not stutter, I can play all my games perfectly fine.
Is there any explanation for what is going on with some of my drives?
you might want to check/change your sata cable with he pin lock ones. i have the same click problem with my WD Black 1TB and it seems the problem is the cable. (freeze my windows, slowdown and the top one, scary click sound etc.etc.)
what is your OS?(i assume vista/W7 from screenshot) are you running on IDE mode or AHCI?
from the looks on the screen shot i assume you migrated from windows xp to vista/w7? if that is the case i have not gone through that yet. but i can suspect that it may because of different chipset (nvidia to intel) that control the harddisk and different operating system (how they cache).
