The hard drive is a frequently used component, and as soon as your computer starts up, it will be reading and writing to the hard drive, so hard drive optimization is very important. The following is the hard drive optimization of the eight tips, if you can put into practice, you can adjust the hard drive to the best state, so as to significantly improve system performance. First, open the DMA transfer mode DMA is a fast transfer mode, open to increase the reading speed of the hard disk or optical drive. If the hard disk supports DMA mode, you should open the mode. Open DMA method: First determine whether the hard disk supports DMA transfer mode (i.e., support for UDMA 33/66 or UDMA/100), with VIA chipset motherboards need to install the VIA 4-in-1 driver; if you support DMA, you can "Device Manager" option of the "Disk Drive". If DMA is supported, you can double-click the hard drive you want to optimize in the "Disk Drive" column of the "Device Manager" option, enter the "Settings" option, and make sure that DMA is selected in the "Options"; then go back to the "System Properties" section and click "Options". System Properties" dialog box, select "File System" under "Performance", open the "File System Properties" dialog box, in the "Options", make sure DMA is selected. Open the "File System Properties" dialog box, in the "Hard Disk" settings, set "Primary Usage of this Computer" to "Network Server", and then set the "Pre-read Optimization" to "Pre-read Optimization". Drag the "Pre-read Optimization" slider to the far right; reboot the system, enter the BIOS setup, and make sure that DMA support is turned on, so that the DMA transfer mode is turned on. Older hard disks (e.g. those under 4GB) may have problems after turning on DMA mode because they do not support DMA, so it is recommended that you do not turn on DMA. Some hard disks that support DMA may also have conflicts within Windows after turning on DMA, the solution is: find the Mshdc.inf file in the \Windows\inf directory, and then add the Mshdc.inf file in the [ESDI_AddReg] subsection. AddReg] subsection at the bottom of the following two lines: HKR,IDEDMADrive0,3,01 HKR,IDEDMADrive1,3,01 Second, the use of FAT32 partition format Before Win 98, the system generally uses the FAT16 partition format, the size of the cluster is 32KB, so that no matter how small the information written to the disk, will at least occupy 32KB, therefore, if the disk is written to the disk, it will take up 32KB. Occupy 32KB, so if the disk has a lot of small files, the waste of space will be very considerable, so the FAT32 format came into being, the cluster size has been reduced to 4KB, which reduces the waste of space on the hard disk. If the hard disk is in FAT16 format, you can use the Windows built-in system tool "Drive Converter" to convert it to FAT32 format. Newly purchased hard disk, Fdisk can be directly partitioned into FAT32 format, generally more than 2GB partition, the best use of FAT32 format. Third, the main partition size should be moderate Windows startup, to find from the main partition, call the system files, if the main partition is too large, it will extend the startup time, so some people's practice is to control the main partition as much as possible in the 2 to 3G between the other partitions according to the size of the hard disk remaining evenly divided into 2 to 3, and then create a size of 400 megabytes of partition as a backup partition. In the main partition to install only the Windows operating system and some essential software, in other partitions to install commonly used software, games, etc., so as to facilitate maintenance and management. But there are still some people heavy in the consideration of the convenience of use, accustomed to only the hard disk is divided into C, D two areas, C area is relatively large, in addition to storing the software system, but also spare a lot of capacity of the temporary file system space, so that it is easy for some of the large data throughput of the program run; D area is to put the personal files. In short, the partition size should be based on the individual situation. Fourth, the hard disk cache optimization settings You can use special software, such as Cacheman (download address /software/item/02157981_2400.html) to optimize the settings of the hard disk cache, Cacheman is Outer launched the hard disk cache optimization software, built-in optimization of several sets of programs (whether it is a system with less memory or a system that often needs to burn CD-ROMs). often need to burn CD-ROM system), you can choose the closest program to optimize the settings according to the machine. Fifth, optimize the virtual memory As physical memory is limited, if Windows executes more processes, the more physical memory consumption, so that the memory will be consumed. In order to solve this type of problem, Windows uses virtual memory (i.e., swap files), using the hard disk to act as a memory to use, but the resulting speed is much slower, because the hard disk access speed than the memory to be much slower, so a reasonable set of virtual memory, you can speed up the system. The method is: open the Windows "Control Panel" → "System" → "Performance" → "Virtual Memory ", adjust the virtual memory settings, decide the location of the virtual memory (on which hard disk partition), the size of the capacity is recommended to choose "Let Windows manage by itself", so that Windows will automatically change the size of the swap file according to the use of memory. Note: the swap file partition must have enough space left, the more the better, at least need more than 200MB of remaining hard disk space, otherwise Windows is prone to insufficient memory error; Secondly, if the machine has more than two hard disks, the swap file should be set on the faster hard disk (such as 7200 rpm hard disk), which can improve the access speed of the virtual memory; Finally, you should often organize the partition where the virtual memory, if the partition has too much debris, will affect the speed of virtual memory. Sixth, disk fragmentation because the hard disk files are not sequentially stored, so the same file may exist in several different locations, so that when deleting the file, it will leave a lot of blank areas on the hard disk of varying sizes, and then save the file, it is necessary to prioritize the filling of these areas, and over time it produces a lot of debris, affecting the efficiency of disk access. To eliminate fragmentation, you need to rely on some tools, such as Vopt99 (download address ), Norton Uti-Kities, etc., Windows also has a built-in "disk defragmentation" tool. It is recommended that you use the above tools to organize your hard disk every once in a while. Seven, the hard disk garbage cleaning to delete all the files in the directory "C:\Windows\Temp", these files are left when the installation of software; delete backup files on the hard disk (with the extension .tmp, .001, .bak), you can search for such files, and then delete it; delete Windows \Delete the help files in the Windows Help folder; Delete useless registry entries in the registry, these are left in the registry when the software is installed, once the software is uninstalled and not deleted, the registry will be too large, affecting the speed of the system. Under "HKET_LOCAL_MACHINE\Software" and "HKET_CURRENT_USER\Software" main keys, find those deleted subkeys and delete them; under "HKET_LOCAL_MACHINE\Software" and "HKET_CURRENT_USER\Software" main keys, find those deleted subkeys and delete them. HKET_LOCAL_MACHINE\Software\MicrosoftWindows\CurrentVersion\explore\Tips under the main key to find those subkeys that have been deleted and delete them; Under HKET_LOCAL_MACHINE\Software\MicrosoftWindows\CurrentVersion\explore\Tips Under MicrosoftWindows\CurrentVersion\TimeZone, delete the redundant time zones and keep only the Beijing time zone; Under HKET_LOCAL_MACHINE\System\Current ControlSet\Control\Keyboardlayouts delete the unused input method. Adjust the Recycle Bin: The Recycle Bin defaults to the same configuration for all drives and has a capacity of 10% of the total capacity of the drive. You can configure each drive separately as needed and set the maximum space of the Recycle Bin to 1% of the partition. For non-primary partitions can also choose to directly delete the file, do not transfer it to the Recycle Bin. Eight, the use of hard disk acceleration software to overclock the hard disk, optimize hard disk performance, but also available hard disk acceleration software SuperFassst! This is a Windows hard disk acceleration software, which uses a unique patented technology to make applications start significantly faster, enhance the Windows multitasking performance, accelerate the speed of the window and menu display, allowing faster copy and delete files. The program can be found in InfoCD No.7.
