The hard disk is the core of the computer. It stores all the files and treatments. It is very important for the individual. Therefore, how to use the hard disk correctly and protect the security of the data is the key. How to use the system home reasonably Suggestions for the hard disk, I hope to be useful to everyone. First, the rational use of hard disk novices, what is the reasonable use of hard drives? First we need to understand the physical structure of the hard disk. A partitioned and formatted hard disk is based on a sector, and a partition is composed of a number of sectors. So what is a sector? We all know that the disk is rotating at work. The information it stores is recorded on its surface in a series of concentric circles. Each concentric circle is called a track. In Figure 1, we can see the track and sector. Distribution (of course, this is just a schematic diagram, the physical object is much denser than the picture!), many friends think that the red "big head" is a sector, but the correct understanding should be the yellow one. One sector. A sector has a size of 512 bytes, a whole ring is a track, and there are several sectors on a track, so it is easy to see that the larger the sector on the outer track, the larger the volume. The words are the lower the density, because the hard disk is mechanical transmission, so the speed of the search, read and write speed of the magnetic head is faster, the distribution of the partition is also from the outer ring to the inner ring, so the C disk is relative to the D disk. Outside, this is why we feel that the C drive is faster than the D, E and other partitions. Understand the above knowledge, we can use the hard drive reasonably! Take a new hard disk with a capacity of 60GB as an example: divide the C drive into 3 to 5GB (depending on the operating system), set the D drive to 1GB, set the E drive to 10GB, and save the watch. (It can be divided into F and G disks) —— has no effect on system speed. How to use after the good zone is the most important: 1. Install the operating system on the C drive and install the common small software such as MwIE, Foxmail, ICQ, QQ, FlashGet, Super Rabbit, player software and some viewing software. On the C drive. If you use Microsoft's large software such as Office, you should also install it on the C drive. Of course, since we don't use all of the features, we have to customize the useful parts to save the C drive space! Then set the virtual memory to the D drive (just temporary ^_^) and then use the system's own disk defragmentation program to organize the C drive. 2, use the system modification software such as "micro-registration optimization master" & rdquo; "My Documents", "Internet buffer", "Internet history", "collections" and so on often Set the folder to be written and deleted to the D drive to minimize the disk fragmentation of other partitions and reduce the performance of the hard disk! 3. Install various application software to the E disk. As for the game, it can be installed on the F disk. The G disk is used to store audio and video files. 4. Perform another defragmentation on the C drive, and then set the virtual memory to the C drive after completing the second big step below! Second, the setting of virtual memory Setting the virtual memory to a fixed value is already a common "truth", and this is very correct, but most people set it to a non-system partition other than the C drive. Up, and its value is mostly 2 to 3 times of physical memory. Most people think that the larger the value, the better the performance of the system and the faster it runs! But this is not the case, because the system relies on virtual memory —— if the virtual memory is large, the system will start to use virtual memory when there is a lot of free space in the physical memory, but those that are not used yet are still Staying in physical memory, this will inevitably lead to a decline in memory performance! So the author started from 32MB memory to 512MB memory, and found that the above fact is very correct, the virtual memory should be set to physical memory 0 to 1.5 times (how much is 0? Is it disabled! ^_^) As well, the larger the physical memory, the smaller the multiple should be. When the physical memory is equal to or greater than 512MB, most PCs can disable virtual memory, and the memory performance is the highest! As for how much your virtual memory needs to be set, you have to give it a try, because this is directly related to the size and size of the resident memory software and the software you usually run, so I can not give the recommended value. . You can set it to be the same as the physical memory before running several large software. If there is no abnormality, you can set it to half of the physical memory before running the large software. If an exception occurs. You must increase the value of virtual memory properly! By analogy, when you find the best value, just set this value to the C drive and it will be OK! Note: If you are using Windows ME and the following operating systems, you can download “MagnaRAM 97” to optimize physical memory and virtual memory, this effect is better! In addition, I recommend that you do not use the so-called software to optimize and organize memory! Third, reasonable placement "shortcuts"; in most cases, we run the software is usually the software's "shortcuts" to do, the hard drive is getting bigger and bigger, the installed software is getting more and more Many, many friends like to put shortcuts on the desktop, which not only makes you dazzled, but also the system performance will be degraded, and will cause the system resources to be too large and the system becomes unstable, so we better put the desktop The shortcuts on the control are around 10, and other shortcuts can be placed in the Start menu and the Quick Launch bar, and all software's “Uninstall” shortcuts are removed to improve system performance. Also, try not to have duplicate shortcuts. This article comes from [System Home] www.xp85.com
