hard drives that damage the hard disk for a long time are the most important storage media in the computer. I believe that every computer user knows about the maintenance of the hard disk. However, many of the previous articles are aimed at single-player users in the dial-up era. Today, as broadband becomes more popular and large hard drives continue to cut prices, many people will let the hard disk run at full capacity as soon as they turn on the computer: watch high-definition DVDRip movies, and continue uninterrupted BT download, use Windows system restore function...
However, you may not know, the new application mode brought by these new software will bring new damage to the hard disk! The hidden danger brought by the new application mode
1. Frequently defragmenting disk fragments
Disk defragmentation and system restore were originally normal functions 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 continuously reads the write data to other clusters, and then moves the data back to the appropriate position after sorting the operations. These operations consume a large amount of CPU and disk resources.
In fact, for the current large hard disk, the proportion of space occupied by documents and mail is very small. Most people buy large hard disks for movie and music. These partitions do not need to be sorted frequently because they play multimedia files. The effect has nothing to do with the disk structure. The playback speed is determined by the graphics card and the CPU.
2. Auto-restart of Windows XP
The auto-restart function of Windows XP can automatically close the unresponsive process and automatically exit the illegal operation program, thus reducing the user's operation steps. However, this feature also has a big problem: it will turn off the hard drive before the automatic restart, and then turn on the hard drive when the machine is restarted! In this way, the hard drive receives current in less than 10 seconds. With two shocks, it is very likely that a sudden "death" failure will occur. In order to save some energy settings so that the system automatically shuts down the hard disk, it is more harmful than the hard disk.
3. The wrong DVDRip
The DVDRip format video that is now compressed by DVD transcription is quite popular. The resolution of this format is almost the same as that of DVD, but downloading a movie is only 700MB~1.3GB, so many users like to download the DVDRip format to the hard disk and slowly enjoy it. However, playing this format of the film has higher requirements on the system: in addition to the CPU and graphics card requirements are strong enough to ensure smooth playback, the hard disk load is also very large - because playing DVDRip is a continuous decoding decompression, and then sent to the display The process of the system.
I found that when encountering a DVDRip file with a coding error, Windows has a very high disk occupancy rate: The system constantly wants to convert the code into a video signal, but the wrong file index and corresponding signal segment It is not matched - at this time, the hard disk light will flash continuously, the whole system responds very slowly to the user's operation, and the user clicks on the menu but almost no response. If there are more coding errors, the system sometimes crashes. 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 if the hard disk head is not properly reset!
Tip: Windows XP users need In particular, when we automatically preview some of the larger ASF, WMV and other files in Windows XP, although there is no official playback, but the computer speed suddenly slows down, the hard disk lights continue to flash, etc., the culprit is still Is the video file error code!
4. Bittorrent download
Bittorrent Download is the emerging P2P exchange file mode in the broadband era, sharing resources among users, as a seed and relay station, commonly known as BT download. Since each user's downloads and uploads are almost simultaneous, the download is very fast. However, it will write the downloaded data directly into the hard disk (unlike the download tool such as FlashGet can adjust the cache, to the hard disk after the specified amount of data), so the hard disk usage is much larger than the FTP download! Br> In addition, BT downloads must apply for hard disk space in advance. When downloading large files, there will usually be 2~3 minutes for the entire system priority to be occupied by the task of the application space. Other tasks are extremely 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.
So, unless your computer hardware configuration is quite high (especially memory, at least 256MB or more), before the BT download is improved, if you want to download long-term, multi-tasking applications, it is best to use the traditional FTP software.
5. The danger of PQMAGIC conversion
PQMAGIC is a famous partition magician who can freely 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 60~80GB hard disk is everywhere. PQMAGIC has long been unable to do it: adjusting the partition with data above 5 GB usually requires 1 More than an hour!
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.
6. The abnormality caused by the hard disk protection software
It is easy to cause the abnormality of the hard disk, and the 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, can not continue, and is in an infinite loop. This 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.
This is just a software failure, but many people are inexperienced. If there is a problem, they will find various partitioning tools to "test" and even rashly and low-level format. Under such a toss, the hard disk is likely to die in advance! Br>
