De-fragmentation of HDD

[epicninja21]

Hello all, I've been questioning on de fragging my HDD, it is a WD Caviar black 1Tb Hard Disk. I was wondering if it's safe to do so. (Never done it before) Just curious as to wether it's safe and roughly how long will it take. Currently have 677GB out of 931GB left.

~Thank you in advance

(win7) search for disk defragmenter, choose your drive and analyze it and if it says like 0-10% you dont need to defrag, if its anything over u might wanna and 50% or over yes do defrag it. its safe and varies how long it will take on how much its fragmented.
