Question 2: What will happen if the motherboard and hard disk are incompatible? This situation is rare, but some hard disks are well recognized on this motherboard, but not on another motherboard. For example, if you want to start from the original 1200 MB small hard disk, you must be in the main disk position of the IDE 1 interface to start normally, otherwise you can read and write after plugging it in, but you can't start it. For the problem of slow hard disk speed, it is generally not a compatibility problem, but a setting or wiring error. For example, the line of DMA66 is connected backwards; The DMA function in the hard disk properties is not turned on; IDE in CMOS setup ..

This feeling is not much, but there are some hard disks that are well recognized on this motherboard, but not on another motherboard. For example, if you want to start from the original 1200 MB small hard disk, you must be in the main disk position of the IDE 1 interface to start normally, otherwise you can read and write after plugging it in, but you can't start it. For the problem of slow hard disk speed, it is generally not a compatibility problem, but a setting or wiring error. For example, the line of DMA66 is connected backwards; The DMA function in the hard disk properties is not turned on; The IDE channel in CMOS setting is not set to automatic, but artificially set to transmission mode below PIO4; The hard disk cable is too long, which leads to excessive data attenuation and reduced transmission rate; There is a problem with the hard disk power interface or the power of the switching power supply is insufficient, which leads to the unstable low power supply voltage of the hard disk. The solution to this kind of problem is to be careful and carefully check the relevant settings of the hard disk. In particular, the line of DMA66 is reversed, and the data transmission rate will drop by half. Furthermore, when data lines are used,

Question 3: The computer motherboard and hard disk are incompatible. The incompatibility between the motherboard and the hard disk is a joke, but there may be something wrong with your system. First try to change the location of the hard disk slot on the motherboard. If not, so be it.
1, find a system disk to start the system with PE, and format the C disk after startup. Install win7 in NTFS format, install XP in FAT32 format, and set disk C as the stalk.
2. Restart the machine, or redo the system to drive C with the CD.
You remove the motherboard bios battery, then install it and restart it later.
Question 4: Is there any compatibility problem with the computer hard disk? If they are not compatible, what will be the impact? As long as it can be loaded, the data can be presented! ! There are no other questions. As for compatibility, there will be problems, but there will be no problems with the data. You need to move them. Moreover, the capacity of the hard disk at that time was similar to that of the current U disk, so it should be easy to transfer! !
Question 5: My computer is now equipped with a mechanical hard disk, and I want to add a solid-state hard disk. Will there be incompatibility between mechanical hard disk and solid state hard disk? Yes, you can rest assured that there will be no problem with the desktop computer. For notebooks, just put the SSD in the hard disk location and the mechanical hard disk in the CD-ROM drive. This is what I need!
Question 6: What will happen to the hard disk so that it can't be used at all? Is it possible to fix it? There are irresistible reasons such as heavy blows or strong current, and sometimes the hard disk is hard enough to be redeemed.
Question 7: Why can't the hard disk read? The five-point method is very simple, which can be explained in detail with the CHDSK command as follows: Start-Run-Enter cmd-Enter the CHDSK drive letter: /f, such as "CHDSK D:/f". Wait until the order is completed. It should be noted here that there should be a space after that colon, and don't write /f failure after that. Whether it's a mobile hard disk or a USB flash drive, including the hard disk partition on the local computer, double-clicking it will prompt: "H disk can't be opened, the file or directory is damaged and can't be read, ...". Some partition formats become original. This error prompt in data loss analysis is caused by the disk file directory (FAT, MFT) error caused by various reasons. It mainly occurs on mobile devices such as USB flash drives, MP3 players, and mobile hard disks, among which the large-capacity (160G or more) external mobile hard disks with NTFS partition format have the highest probability. There are many reasons for this. Generally, there are the following reasons: 1, the mobile device is not plugged in and out normally, and the system has not completed the complete reading and writing operation, resulting in the confusion and incompleteness of file directory information. For example, when we copy a file to a mobile device, we will have symptoms when we shut it down, restart it, unplug it, reopen it, or use it on another computer. 2. Choose inferior products, including inferior power supply, motherboard, data cable, especially inferior external hard disk box. The power supply and main control circuit of the product are unstable, which leads to the error of disk addressing and the confusion of writing information. 3. Use disk partition adjustment tools such as PQ and PM. 4, virus, hard disk hardware itself failure, sudden power failure during work. Quality of recovery effect If it is a large mobile hard disk and NTFS partition format, the recovery quality is very ideal, and basically all files and directory structures can be successfully recovered. If it is in FAT or FAT32 format, according to the damage degree, the recovery quality effect is slightly worse than that of NTFS format partition, so it is recommended to use NTFS format partition every day, which has higher data security. I don't know who started preparing for data recovery. Someone on the internet told you to format the partition first, and then use some data recovery software to recover the data, big brother! Big brother! ! Big brother! ! ! Don't do this. After formatting, especially the FAT format partition, the restored data directory structure is incomplete, especially the most needed files that are frequently edited. Because of many file fragments, the recovery software lost the comparative analysis of the FAT table, and most of the recovered files could not be opened. It is recommended to make a mirror backup before the following operations! If you want to take a shortcut, you can try your luck first, and you can try CHKDSK (the method mentioned at the beginning of this article) first. Chkdsk is a disk check and repair command attached to Windows operating system. Look at the drive letter of the failed device first, then click-Start-Run, enter CHKDSK H:/F in the Run dialog box, and press Enter. Please note that H is the drive letter you want to check and repair. After that, the system will start to check the disk partition. If the system can find the problem and it is within the repair capability, Windows will automatically repair the faulty partition. If there is no response, don't unplug the device, restart the computer and try. If the fault remains, it means that you have won the senior prize! What if I win the senior prize? Don't be discouraged! ! ! There's always a way. I once repaired it with the hard disk partition table repair tool, but it didn't work. Forget it, I won't restore the partition. Many experiments have completely disappointed me. Now we should consider how to recover the files in the partition, because this is the most important thing! I use EasyRecovery. After a long wait, the data finally recovered. All the files I recovered were lucky, but some directories were missing. Fortunately, as long as the file is there, it's years of hard work! ! ! In addition, it is said on the Internet that R-STUDIO can also be used. There is no attempt this time. I used R-STUDIO to restore the data in the USB flash drive before, and the effect is good!

Question 8: Is there a compatible or incompatible hard disk? How many interfaces does the hard disk have? There are only several types of interfaces: sata, msata, ide scsi sas.
Sata is divided into 1 23rd generation,1generation speed 1.5g, 2nd generation speed 3g, 3rd generation and 3rd generation speed 6g.
Msata is the same as sata, but the interface is different. Generally, it is a mini pcie directly plugged into the motherboard.
Ide interface is relatively old, and it is a parallel interface of the previous generation, which is divided into ide33 66 100.
Scsi and sas are mostly used in servers, which are hardly seen at home. Scsi also has several different speeds, but now it has basically been eliminated. For details, please refer to baike.baidu/view/26111? Fr = Aladdin
Sas is the mainstream interface now, please refer to baike.baidu/view/196833 for details.
As long as the interfaces are the same, there will be no incompatibility, but the speeds are different, but they are all backward compatible. There are sas motherboards or array cards that can plug in sata hard disks, but sata interface motherboards can't plug in sas hard disks, which is basically the case.
Of course, there are also some wonderful interfaces, such as the ce interface between Sonny and Panasonic cameras, and the cf micro-hard disk, also called cf card, which is actually an ide interface and can be directly connected to the ide port.
Question 9: What will happen to a computer with incompatible memory chips? Will it affect the hard disk? Incompatibility of memory modules will not affect the computer hard disk, and usually will not damage other hardware, but it may cause blue screen of death or failure to start the computer.
Question 10: What does the compatibility of notebook hard disks mean? Because PC is easy to assemble and has strong expansibility, it has accelerated the popularization of computers to a certain extent, and computer accessories manufacturers have naturally made great contributions to this. However, it is precisely because the computers we use (especially compatible computers) are composed of products from different manufacturers that they will inevitably "rub" with each other. This is what we usually call incompatibility, and the so-called "compatible machine" also comes from this. Next, I will talk about what kind of incompatibility will happen between components and how we can solve this problem.
1. Memory is not compatible with motherboard.
Incompatibility between memory and motherboard is common, indicating that the computer was fine yesterday, and it kept ringing as soon as it was turned on this morning. Just open the case, remove the memory module and plug it in. Note: When unplugging the memory module, be sure to unplug the host and power cord to prevent accidental memory burning. This is a small mistake. If it is serious, you need to wipe several memory sticks several times to turn on the machine. But in less than ten and a half days, there will be another alarm. Just open the case and plug in the memory. You said there was something wrong with the machine. As long as it is on, there is no problem running for ten and a half months in a row. No one can stand calling the police all the time. This situation is that the typical memory is not compatible with the motherboard.
The reasons for the failure are:
(1) The memory stick is not standardized, and the memory stick is a little thin. When the memory is inserted into the memory slot, there is a certain gap. If there is vibration or dust falling during use, it will cause poor memory contact and alarm.
⑵ The gold finger technology of the memory stick is poor, and the surface of the gold finger is not plated well. In the process of long-term use, the oxide layer on the surface of the golden finger gradually thickens, and when it accumulates to a certain extent, it will cause poor memory contact, and the memory will give an alarm when it is turned on.
(3) The quality of the memory stick is poor, and the contact between the reed and the gold finger of the memory stick is not real. There are always hidden dangers in the use process, which will not light up at a certain time and will turn on the alarm.
(4) Then there is pure incompatibility: a note works well on some motherboards, but it often crashes or fails to start normally on this motherboard. This is a typical incompatibility.
Treatment plan:
(1) Carefully wipe the gold finger of the memory stick with an eraser and reinsert it into the slot.
⑵ Fill the gaps on both sides of the memory slot with hot melt adhesive to prevent further oxidation during use.
(3) If the alarm still appears after a period of use, you can replace the memory stick first to see if the alarm still appears in the later use process.
(4) If the memory alarm appears after a period of time, only the motherboard can be replaced to completely solve the problem.
For the case that the memory module is incompatible with the motherboard due to technical problems, only other brands of memory modules can be replaced, and of course the motherboard can also be replaced. For example, KingMax's memory is not compatible with Pan Ying's motherboard. As long as the two are combined, a blue screen will appear.
2. The keyboard is not compatible with the motherboard.
The incompatibility between keyboard and motherboard is mainly due to the poor quality of keyboard and mouse. The data sampling speed of the chip is inconsistent with that of the motherboard, and keyboard errors will occur irregularly during use.
Main fault performance:
(1) Check the keyboard or mouse irregularly;
2 keyboard or mouse lost in use;
(3) There is also the fact that the mouse has no arrow indication during use, but it can operate normally or the arrow is lost;
(4) When dragging the mouse, sometimes a box moves with the mouse arrow.
5] When the machine wakes up with the machine after sleeping, the mouse can't be used, so you can only restart the computer or unplug the mouse and plug it in.
This situation is generally not the problem of the motherboard, just replace the qualified keyboard and mouse.
3. The graphics card is not compatible with the motherboard.
Fault performance:
First, the manufacturing process of graphics card is not standardized, which leads to short circuit after being inserted into AGP slot, which shows that there is no electricity.
Second, the graphics card sometimes works normally and can light up the display; Sometimes it turns off the monitor irregularly. However, it is completely normal for the graphics card to be plugged into other motherboards. In this case, only the graphics card can be replaced.
Third, the computer host is also working normally, and the image display of the monitor is also normal, but it is occasional and irregular.
Fourth, as long as you use this graphics card, the system will be unstable, or often crash, or often lose the graphics card driver. In this case, it may also be because of the obvious >>
