Preventive software triggers six "hard injuries" on hard drives

The hard disk is the most important storage medium in the computer. Regarding the maintenance of the hard disk, I believe that every friend who has used the computer knows it.

However, as broadband becomes more popular and large hard drives continue to cut prices, the load on hard drives will be even greater.

When we watch high-definition DVDRip movies, uninterrupted BT downloads, use Windows's system restore function, etc., the application of these softwares invisibly brings absolute "hard" to the hard disk.

A badly wounded one: the wrong DVDRip

Now the DVDRip formatted by the DVD transcription is usually only 700MB~1.3GB, and the resolution of the movie is almost the same as that of the DVD. People are welcome. However, the hard disk load is very large when playing movies in this format. Because playing DVDRip is a process of continuously decoding and decompressing and then delivering it to the display system. Especially when encountering a DVDRip file with a coding error, Windows will have a very high disk occupancy rate. At this time, the hard disk light will flash continuously, the system response will be very slow, and sometimes it will crash. Many users are very impatient at this time, directly press the Reset button on the chassis or even directly turn off the computer power. This operation is quite dangerous when the hard disk head is not properly reset!

Tip: When automatically previewing some large ASF, WMV and other files in Windows XP, if the system speed suddenly slows down and the hard disk light flashes, the culprit is still the video file error code.

Mitigation: Resolving coding errors

The best way to encounter a video file with a coding error is to issue a shutdown or restart command to the system through the normal way, and wait patiently for the system to handle it yourself. Restart your computer. Then go online and search for some software that fixes coding errors to fix these videos and watch them.

Hard 2: BT Download

BT download is an emerging P2P exchange file mode in the broadband era. Users share resources and act as seeds and relay stations. Since each user's downloads and uploads are almost simultaneous, the download is very fast. However, it will write the downloaded data directly to the hard disk, so the hard disk usage is much larger than the FTP download.

In addition, BT downloads must apply for hard disk space in advance. When downloading large files, there will usually be 2~3 minutes. The entire system priority is occupied by the task of the application space. Other tasks are very slow. . In order to make full use of the bandwidth, some people will also perform several BT download tasks at the same time. At this time, it is very easy to cause a crash due to excessive disk usage.

mitigation plan: increase system cache

For BT like this thread is not optimized, while reading and writing to the hard disk software, if you must use, you can modify the registry Ways to increase the disk cache to reduce the frequency of hard disk read and write. Take Windows XP as an example:

Click "Start → Run", type Regedit and press Enter to open the Registry Editor. Expand the "HKEY_LOCAL_MACHINE\\SYSTEM\\CurrentControlset\\Control\\SessionManager\\

MemoryManagement" branch, create a new DWORD value, name it "Iopagelocklimit", and set its value to "4000" (hexadecimal, That is, 16MB) or "8000" (ie 32MB), so the read and write frequency of the hard disk will be reduced a lot. For the problem of excessive CPU usage caused by BT, you can solve the problem by adjusting the priority of the task: press "Ctrl+Alt+Delete" at the same time under Windows 2000/XP, select "Task Manager", and then click On the Processes tab, right-click on "Btdownloadgui.exe" and select a level below "Standard" under "Set Priority".
Hard injury three: the danger of PQMagic conversion

PQMagic is a famous partition magician, free to adjust the partition size and format without destroying the data. However, when PQMagic was just launched, the average user's hard disk is about 2GB, and now 60GB~80GB hard disk is everywhere, PQMagic has long been unable to do so. It takes more than one hour to adjust a partition with more than 5 GB of data.

In addition to the influence of capacity factors, when PQMagic adjusts the hard disk partition, a lot of time is spent on verifying the data and detecting the hard disk. It can be seen that in this case, "lossless partitioning" is difficult to guarantee. : Because the conversion speed is very slow and takes too long, during the conversion adjustment process, it is easy to lose data due to factors such as computer power failure and crash. This loss is usually caused by one or several partitions being lost, or the capacity becomes abnormal. In severe cases, the data of the entire hard disk may not be read.

Mitigation: Accelerating the operation of PQMagic

Open "PartitionMagic Preferences" under "General" option in PQMagic, "Ignore OS/2 EA error on FAT" and "Jump" The "bad sector check" option is selected, ignoring the process of verifying the data and detecting the hard disk will naturally speed up the PQMagic. Of course, before using PQMagic to operate the partition, we should first use the disk scan tool to check and eliminate the error on the hard disk, and then perform the partition conversion operation.

In addition, it is best not to use PQMagic to adjust the partition with data, not to change the partition format when partitioning format.

Four injuries: abnormalities caused by hard disk protection software

It is easy to cause abnormal disk, and hard disk protection software. For example, "Restore Wizard", because many people do not pay attention to reinstalling the system or re-partitioning it to uninstall it normally, often the system can not be completely installed. At this point, I want to install and uninstall the Restore Wizard, but I am prompted that the software has been installed and cannot continue. I am in an infinite loop. This type of failure is due to the fact that the Restore Wizard took over the INT13 interrupt and controlled the boot of the hard disk before the operating system, which could not be solved with the FDISK/MBR command. Originally this is just a software failure, but many people are inexperienced. If something goes wrong, it will find various partitioning tools to "test" and even rashly and low-level formatting. Under such a toss, the hard disk is likely to die in advance.

Mitigation: Uninstalling the Restore Wizard

If you forgot to uninstall the Restore Wizard correctly before reinstalling the system, you will not be able to partition and install the system. To solve the problem. Put the "Restore Wizard" installation CD in the CD-ROM drive, find the uninstaller Uninst.exe and execute it. When the prompt "Can't run on... Do you want to restart the computer?" appears, click "OK", after restarting Then install the Restore Wizard and then uninstall it. This method was verified in the "Restore Wizard" 5.0, 2002, 2003 and other versions.
Hard injury five: Frequently defragmenting disk

Disk defragmentation and system restore is a normal function provided by Windows, but if you do these operations frequently, it is harmful to the hard disk. The defragmentation needs to perform the underlying analysis on the hard disk to determine which data can be moved and which data cannot be moved, and then sort and sort the files. Before the hard disk data structure is formally arranged, it will continuously read the write data to other clusters, and then move the data back to the appropriate position after sorting the order. These operations will consume a large amount of CPU and disk resources.

Mitigation scheme: partitioning with NTFS format

Since the cluster of NTFS partition itself is very small, it is not easy to generate disk fragmentation. Microsoft also made special treatment on file allocation table and directory index. It is also easier to recover files after an error. If you want to ensure system compatibility, it is best not to set the boot partition to NTFS format.

Hard Six: Automatic Restart of WinXP

The automatic restart function of Windows XP can automatically close the unresponsive process and automatically exit the illegal operation, thus reducing the user's operation steps. However, this feature also has a big problem: it will turn off the hard drive before automatically rebooting, and then turn on the hard drive when you restart the machine. As a result, the hard disk is subjected to two current surges in less than 10 seconds, and a sudden "death" failure is likely to occur. In order to save some energy, it is set to let the system automatically shut down the hard disk, which is more harmful than the hard disk.

Mitigation:

1. Disable automatic restart function

Right-click "My Computer" in Windows XP, select "Properties", and then click "Advanced" tab, click the "Startup and Recovery" button, in the open interface, clear the check box before "Automatic restart" under "System failure".

2. Turn off the hard disk energy saving function

First set the hard disk energy saving to "DISABLED" in the power option in the BIOS, then in the "Control Panel Power Options" of Windows, " Under "Power Scheme", "Turn off the hard disk" and "System standby" are set to "Never" (to make the system shut down and hibernate, or to control it manually).
