Computer Operation taboos: devastating hardware misoperations

This article describes errors and operations that may cause devastating hard disk faults, rather than general disk and system errors. These faults usually do not have a precursor. Once they occur, the hard disk cannot be recognized in the BIOS, the possibility of restoring hard disk data is extremely small.

Generally, S is added to all hard disks. m.A. r. t's automatic detection technology enables users to see a precursor before a fatal fault occurs and back up data-but this is designed for normal operations, if the user uses the following methods, the fault may occur without warning, that is, the sudden death.

I. Suddenly force-cut off the power supply during power-on and power-off

The current power supply and the ATX design of the motherboard generally implement the soft shutdown function. This design is very convenient. However, soft shutdown must first complete a series of operations to shut down the running program, coupled with the compatibility and bugs designed by various operating systems and motherboard manufacturers, windows Often crashes when applications are shut down and the power is cut off. You may find that in the Q & A column of many forums and newspapers, I have seen the question "Why is the hard disk crashed during soft shutdown?"-at this time, the hard disk reset operation may not be completed yet. If the user forces the power supply to be cut off, there is a high possibility of physical damage to the hard disk.

* Correct practice: if the system crashes during soft shutdown, press the RESET key to re-enter the system to Windows and then officially complete the shutdown operation. This may be a little complicated, but it can ensure that the hard disk can be safely reset. For your hard disk of thousands of yuan, security is the first.

Also, the power is cut off when the instance is started: Normally, no one will do this boring operation, however, when the display card or memory is not properly inserted or the video line is loose, the computer is not displayed when it is started up, many people just concentrate on solving the problem, frequently boot, shutdown, board plugging, and then boot ...... I didn't pay attention to the noise of the hard disk on and off the power switch again and again-especially when it is not displayed, it only takes a few seconds. The initialization of the hard disk has not been completed, and the head is in a sensitive position, suddenly shut down by the power supply, and then under the current impact in less than 10 seconds, the probability of failure will greatly increase.

* Recommended Practice: Unplug the power cord of the hard disk first. It is not too late to connect after troubleshooting.

Ii. misoperations on partitions

This is indeed a lot of new-user errors-various versions of Windows have caused the existence of FAT16, FAT32, and NTFS formats, different tasks make cainiao eager to change the partition format. Currently, GHOST and pqpartition masters can perform arbitrary operations on the partition to adjust the partition size and format, in particular, the latter also has the function of formatting and hiding partitions. For those familiar with operations, these tools are handy, but for new users, they should be especially cautious about partition operations. Although the partition error is a soft fault, it is not a physical fault, but if you do not understand the basic concept after a random operation error, you can perform the "Restore" operation without thinking about it, it may lead to too much confusion in the boot and partition tables of partitions and cannot be identified by any tool software. If you do not have a partition table or hard disk boot data backup, hey, I had to use low-level formatting-the use of low-level formatting tools also had a skillful and knowledgeable problem. I have seen many cases where the new hard disk cannot be used due to incorrect partitioning operations.

* Recommended measures: No matter whether you are a newbie or a newbie, back up the partition table and boot area data when performing sensitive operations on the hard disk, and restore the data correctly at any time when an error occurs. It is best for a newbie to ask a master to take the belt first, familiarize himself with the software interface and instructions, and then operate it on his own. After all, the hard disk is different from other accessories, and there is your valuable data in it.
Iii. Windows initialization and dangerous operations during use

Windows Initialization is a sensitive and dangerous time. If you load too many things in the startup group, Windows initialization will take a lot of time, it may also cause crashes, especially when two or more firewalls or online monitoring of virus software are loaded for fear of viruses. There is a high chance of conflict between anti-virus software.

In addition, Windows provides the function of switching applications with the TAB + ALT key, especially when switching back to the Windows interface in the DOS window, this facilitates users who want to work in old applications. However, because DOS is a single-threaded operating system and its applications are also designed based on such threads, DOS applications have a high CPU usage because of the problems with the old DOS architecture, the program does not respond quickly to Windows programs. Therefore, when performing Windows DOS window operations, we recommend that you do not perform these operations so quickly that the system does not respond as quickly as possible. In addition, exercise caution when using TAB + ALT switchover. Do not force the switchover before the program completes the current task, resulting in a crash.

Windows errors will not directly cause physical damage to the hard disk. However, these are habits of use. Once or twice it doesn't matter. It takes a long time, and frequent crashes and restarts. The impact on hard disks and even computer accessories has accumulated a lot of harm; in addition, frequent crashes can easily lead to psychological impatience, and may be forced to shut down before the computer restarts, that is, the possibility of the first type of fatal failure. There are also a variety of bad habits such as shutting down without exiting Windows programs, unsorting hard disks for a long time, and not running disk scanning programs (most common in some public computers, may bury the root cause of Hard Disk destruction.

* Recommended measures: these are basic things. Pay attention to changing the usage habits, such as anti-virus software online. You can click one to change other items on a regular basis, however, it is not suitable for running too many tasks in the background at the same time. The operations with other standards are mentioned in many empirical articles.
IV. Other unconventional errors

For example, data line insertion, poor power supply, board short circuit, and so on, there are many cases in various newspapers and periodicals websites. I will not list them here.

Summary:

The hard drive competitor mentioned above may not be able to cause a fault immediately after such an operation, but there is a high probability of damage-you are still playing games today and surfing the Internet well. After you turn it off, there will be no prompt tomorrow, the system cannot find the hard disk. Please check your practice and pay attention to improvement. It is very dangerous to maintain your hard disk with temporary support and try again when something goes wrong, unless your luck is always so good!
