Some of our friends when using the notebook just for the sake of their mobility, often hard to read and write even when he was still mobile notebook, does not know that this is the hard disk fear of a move. Hard disk reading and writing process, the magnetic head and the disk is no contact between the body, through the hard disk of high-speed rotating body, head and the gap between the plate body is only a fraction of the distance of dust. If this time, then move the hard disk, and disk heads will have direct contact with body, the obvious consequence that had the hard drive bad sectors. An action may seem casual, but can cause irreversible damage to the hard disk. But there are exceptions to this problem that the APS IBM hard drive protection system. In IBM's R50 and T41 models after, all equipped with the system. The major function of this system is to ensure that the mobile notebook user, stop reading and writing on the hard drive in order to protect the hard disk. In fact, during data read and write only when the hard disk head will move to the plate body, if there is no data to read and write requests, then the head will be away from the plate body, this time the movement of the normal hard disk will not cause any harm . But the system only supports Windows XP or Windows 2000 systems of internal hard drive. But also in the laptop's sleep mode, the shutdown process in the system can not boot. Actually, no matter whether your notebook to do to protect APS technology, in everyday use, if you encounter hard drive is reading and writing, he should avoid mobile notebook. I think this is to protect the most fundamental way laptop hard drive, after all, which is the most valuable data, once damaged, I am afraid of its consequences, only you know oh.laptop battery laptop battery Power tools battery Camcorder Battery Digital Camera Battery CANON Camcorder Battery JVC Camcorder Battery PANANSONIC Camcorder Battery SONY Camcorder Battery
