Improper use of software to damage the hard disk

1, coding error of the DVDRip

The video is now quite popular on the Web by DVD-Transcribed compressed dvdrip format. This format of the film definition and the same as the DVD, but download a movie only 700MB~1.3GB size, so many users like the DVDRip format of the film download to the hard disk slowly appreciate. However, the playback of this format of the video system has a higher requirements: In addition to CPU, graphics card requirements strong enough to ensure smooth playback, hard disk load is also very large-because the playback dvdrip is a continuous decoding decompression, and then transported to the display system process. The author found that in the case of a dvdrip file with coding errors, Windows will have a very high disk occupancy rate: The system is constantly trying to convert the encoding to video signal, but the coding error of the file index and the corresponding signal segment is not matched-at this time, the hard drive lantern flashing constantly, The entire system responds very slowly to the user's actions, and the user clicks on the menu but has little response. If there are more coding errors, the system can sometimes even panic. Many users at this time very impatient, directly press the reset button on the chassis or even directly off the computer power, in the hard disk head is not normal reset, this operation is quite dangerous!

Tip: Windows XP users need special attention, when we automatically preview some of the larger size of ASF, WMV and other files in Windows XP, although no formal playback, but there will be a sudden slow computer speed, hard drive lights flashing, and other phenomena, The culprit is still video file error encoding!

2, BitTorrent download

BitTorrent download is a new era of broadband P2pjiao change file mode, the sharing of resources among users, each other when the seeds and relay stations, commonly known as BT download. Because each user's download and upload is done almost simultaneously, the download speed is very fast. However, it will download the data directly into the hard disk (unlike FlashGet, such as download tools can adjust the cache to the specified amount of data to write to the hard disk), so the hard disk occupancy rate than the FTP download is much greater!

In addition, BT download in advance to apply for hard disk space, in the download of larger files, there will generally be 2-3 minutes of time the entire system priority is occupied by the application space, other tasks are very slow response. Some people in order to make full use of bandwidth, but also for several bt download tasks, at this time it is very easy to appear due to high disk occupancy rate caused by the panic failure.

Therefore, unless your computer hardware configuration is high (especially in memory, at least 1GB above), otherwise in the BT download to make improvements, if you want to carry out a long time, multitasking download applications, it is best to use the traditional FTP software.

　　3. The danger of pqmagic conversion

Pqmagic is the famous division magician, can adjust the partition size and format freely without destroying the data. However, Pqmagic just launched, the general user's hard drive is about 2GB, and now 60~80GB hard disk is everywhere, Pqmagic has been powerless: adjust with data, 5GB or more partitions, usually need more than 1 hours!

In addition to the impact of capacity factors, pqmagic adjust the hard disk partition, a large amount of time spent in validating data and testing the hard disk, you can see that in this case "lossless zoning" is very difficult to guarantee: because the conversion of the speed is very slow, time-consuming, conversion adjustment process, it is easy because of computer power off, Crashes and other factors cause data loss. This loss is usually caused by one or more partitions being lost, or the capacity becomes abnormal, and even the entire hard disk's data cannot be read when it is severe.

　　4, the hard disk protection software caused by the exception

Easy to cause hard disk abnormal, there are hard disk protection software. For example, "Restore the wizard", because many people do not pay attention to reinstall the system or repartition before it normal uninstall, often occurs the system can not be completely installed and so on. At this point, you want to install and uninstall the "Restore Wizard", but also prompts the software has been installed, cannot continue, into a dead loop. This failure is due to the "Restore Wizard" took over the INT13 interrupt, in the operating system before the drive to control the boot, with FDISK/MBR instructions can not be resolved. Originally this is just a software failure, but many people experience, out of the problem will find a variety of zoning tools "test", and even lightly low-level format, in such a toss, the hard drive is likely to premature death!

　　5, frequently defragment the disk

Disk defragmentation and System Restore are normal features provided by Windows, but if you do these frequently, it is harmful to your hard disk. Disk collation to the hard drive for the bottom analysis, to determine what data can be moved, which data can not be moved, and then sorting the files. In the formal arrangement of hard disk data structure, it will continue to randomly read to write data to other clusters, in order to move the data back to the appropriate location, these operations will occupy a large number of CPU and disk resources. Actually, for today's large hard drives, documents and mail occupy a very small proportion of the space, most people buy large hard disk is used to install movies and music, these partitions do not need to organize frequently-because the effect of playing multimedia files and disk structure is not related to the playback speed is determined by the graphics card and CPU.

　6. Automatic restart of Windows XP

The automatic restart of Windows XP can automatically turn off unresponsive processes and automatically quit illegal programs, reducing user action. However, this feature also has a big problem: it will turn off the hard drive before the automatic reboot, and then turn on the hard drive power when the machine is restarted! As a result, the hard drive in less than 10 seconds of time interval, by the current two shocks, it is likely to occur a sudden "death" of the fault. In order to save some energy settings to allow the system to automatically turn off the hard drive, the hard disk is more harm than good
