Such a healthy balance my hard drive?

I have a few DVR's hard drive should be hearing ….
make HDtune used to scan the test when there is an emergence of the hard disk Click Click sound a bit like a spring …..the voice of a pretty ring The five-meter range can be heard …and then do MHDD after testing found more than 1,500 green area (that is the time to read than most of the region longer) …but this last set through Seagate The official short test …

to ask you to do the right health plan? Other so hard in the test of time are silent

normal speed should be a little busy little problem.Head set to play a little bit, there should be a logical or Bad Track Bad Track, the proposed site for a comprehensive scan, if the logic of Bad Track needs a low-level format If the physical Bad Track, zoning tool used to distinguish between bad area to hide, you can use a fine of normal.
