Default Noise lustration methods (2)

Noise lustration methods------Hard disk

Hard disk noise mainly comes from the magnetic head. First because that when it reads, it makes sounds like “Cici” by rubbing against the diskette. Another “Gedeng….Gedeng….” noise is from disk

hot-rectification. This problem can be solved by upgrading to latest Fimeware program. Such as early ThinkPad laptops with Hitachi hard disk, the disks have obvious clear sound of hot-rectification, at first sight, you may think that it’s broken, actually, you should just download latest Fimeware program to refresh from IBM website. And the problem is solved.

Encapsulation also causes the noise to some extent; some manufacturers use a special encapsulation method to lower the noise effectively, such as Panasonic CF-R1, which didn’t adopt the design of general disk bracket style, but a special sponge to pack up. It is not only free from outside concussion, but also of effect of certain sound insulation. We can follow the lead of CF-R1, pack up a flat of thin sponge on the hard disk of your own laptop to lower the noise. This is similar to TP600 laptops with 12.5mm hard disk. You can replace the 12.5 mm disk with standard 9.5mm one to leave spare room for the sponge.
