First of all, we need to understand how to call the "hard drive", because in the current Windows system environment, not only users in the use of the application software has read and write instructions to send the hard disk load, but may be in any idle situation, Defender, SuperFetch and other services will work in th

hard drive has a physical bad way to do
HDD has a physical bad way solution one:
For the physical bad, the average user can not repair, the only thing we could do is to use some disk software to separate it into a single area and hide it, so that the head no longer read it, which can extend the hard disk life to some
root cause.
Suggested measures: These are basic things, pay attention to change the use of the habit is, such as online anti-virus software, hanging a can, periodically transform other, but at the same time the background is not suitable for running too much. The correct operation of other standards is mentioned in many empirical articles, not much here.

-effective bit corruption can generally also be enforced with FDISK/MBR override resolution. Partition table corruption is troublesome, because the partition is not recognized, the system will treat the hard disk as an unpartitioned bare disk, resulting in some software can not work.
There is also a form of partition table corruption, which I would like to call "Partition mapping", which shows the same par
