The hard disk is broken and the computer cannot enter the desktop, but there is still a lot of data

You can detach the hard disk 1 and hang it on another computer that can be booted, if you don't know how to set it up when you hang two hard disks, you can connect the data cable of the other bootable computer to the optical drive to your little bad hard disk. This will allow you to copy out the files you need.

Pay attention to distinguish between the bootable computer hanging on your hard disk 1, and the corresponding drive letter after booting.

Usually, there is a habit of storing files on the desktop. : documents and setti,ngs administrator(username) Desktop. This one?

It is the drive letter, which usually changes to d on your new computer, with some exceptions. You can look for it.

It is recommended to use the U disk to start the MHDD professional hard disk tool software in the DOS tool to scan and repair the bad sector, if Hu Jinguo can not be repaired, you can only replace the new hard Zheng trace disk. The data in the disk can be recovered by a professional data recovery company.

This answer applies to most computer models.

The operating system is installed on the hard disk, and if the hard disk is damaged, of course the operating system cannot be accessed.

1. Advanced BIOS, see if the hard disk can be recognized, if not, the hard disk must be broken.

2. Use the PE system disk to boot into the PE, check whether the hard disk can read and write, if it can't read and write, can't open, can't format, etc., the hard disk is also broken and needs to be replaced.

3. If it can be formatted, after the hard disk is formatted, reinstall the system.

Just reinstall it. The probability of hardware failure is not high. Hard drives usually have a clicking sound before they break down, and the latter has things like a hard bang.

The hard disk has bad sectors, use software to fix it.

There are two kinds of bad problems: physical and logical.

If it's physically broken, replace the hard drive.

If it's logical, it's good to repartition the system.

Additional: The wrong settings of the motherboard may cause the hard disk to be unable to read and enter the system, resulting in an error report on the hard disk.

If the SATA cable or IDE cable is broken or loose, it can also cause the motherboard to throw a hard disk error.

Suggestion: 1. Replug the hard disk cable in the computer first.

2. Replace the hard disk data cable.

3. Repartition to make a new system. (If you want Windows original, you can't use gosht, if the hard disk needs an ICH driver, you need a Windows disk with ICH).

4. Replace the hard disk with a new one and test whether the hard disk is faulty.

That is, the computer tells you that you need to buy a new hard drive.

I shouldn't have recognized the hard drive, so you'd better copy the error sentence and take a look

What's shown? As far as I know, the error message does not display Chinese, so what is the original word it displays?

Method 1:

Start with the simplest method. With the help of the Disk Scan tool under Windows, select the drive letter in Explorer, right-click, and select the "Properties" command from the pop-up menu.

In the pop-up Properties dialog box, switch to the Tools tab: and then click the Start Check button in Troubleshooting.

Then tick the two checkboxes inside and click the "Start" button.

Since it is a system partition, a prompt will pop up to access whether to restart the self-test, and it is recommended to restart the computer here.

After restarting, it will be scanned and repaired before entering Windows, and the scanning time will vary depending on the disk capacity and scanning options, which generally takes a long time, usually about an hour.

Method 2: Use DM to fill in the zeros.

After starting DM, press "Alt M" in the main interface of DM to switch to the advanced menu, and select the "(M)Aintenance Options" command in the menu.

Then select the (u)tilities item from the Maintenance Options menu list.

DM will then display a list of the found drives, select the drive you want to work on, and press enter.

Select the hard disk, and then select "Zero Fill Drive" to fill in the disk.

A warning window will pop up, select "yes" to confirm and continue.

After confirmation, the zero-filling operation will begin, and the zero-filling operation will take a long time, at least half a day to prepare.

After finishing, partition and install the system according to the normal method, if it still doesn't work, it will be used as a portable hard disk.

1. First of all, we open the interface of Master Lu's computer management software and select the hard disk detection button.

2. Select the hard disk detection interface to select the hard disk partition that needs to be detected.

3. After selecting the hard disk to be detected, click the start button.

4. If the hard disk capacity is relatively large, the detection time will be relatively long, and we can check the detection progress in the detection interface.

6. As shown in the figure below, the red box on the right side of the information bar indicates that the module being read is relatively slow and may have logical bad sectors. If a red module is displayed, the module icon currently being read by the hard disk is corrupted.

7. If the red module of the hard disk is damaged, it is recommended to replace the hard disk, if the number of red modules is not large, we can use the bad sector detection tool to repair or shield the bad sector to repair the hard disk.

8. Next, we use the bad sector detection tool to perform bad sector detection on the hard disk.

9. You can select a partition of the hard disk for quick detection.

10. The detection tool of the bad sector starts to detect the hard disk, and the read speed is relatively fast, and it will be displayed well.

11. After the detection is completed, if the logical bad sectors are found, we choose to repair the bad sectors to repair the hard disk.

Hard disk faults are divided into two categories: physical faults and soft faults, and their diagnosis is mainly based on the phenomenon after the system is powered on and the prompt information that appears on the screen. When a hard disk fails, you should carefully analyze the fault phenomenon to determine whether it is a soft fault or a physical device damage. Don't blindly remove the cover, unplug the control card, or easily format the drive at a low level, further complicating the problem.

Sometimes, due to improper maintenance operations, not only the fault is not repaired well, but a new fault is caused.

Three types of computer hard disk failure phenomenon, causes and treatment methods:

If the error on the screen is caused by damage to the battery on the system board to maintain the CMOS information, the CMOS content is lost. For this kind of failure, you only need to replace the battery, reset the CMOS parameters (especially the hard disk type parameters and the three basic logical formatting parameters), and you can boot from the hard disk normally.

When the system starts, the following message appears on the screen: "Invalid Drive Specification Invalid Partition Table" message appears"deviceerror", which is usually an error recorded in the main boot area of the hard disk. This type of error can be caused by:

The master boot partition is not specified as the active partition (no bootstrap flag), several partitions have no bootstrap flag or multiple bootstrap flags, the master boot record end flag (55aa) is missing, and the master boot record is corrupted due to accidental user operation or virus intrusion.

When the system boots, the following message appears on the screen: "Error load operation system missing operation system non-system disk or disk error disk book failure" This kind of error message is usually caused by the error of the DoS boot sector. During the boot process of the system, when the main boot partition of the hard disk is checked correctly, the DoS system boot sector is read according to the partition start address indicated in the bootstrap partition, and if the read operation fails, an error message of "error load operation system" is givenIf the DoS boot sector can be read correctly, the system will check whether the last two bytes of the boot sector are valid with the flag "55AA", and if not, it will give an error message of "missing operation system".If the hidden file name information in the DOS boot sector is corrupted, or if the first two file names read by the bootloader from the start sector of the disk root directory are not the two system hidden files of the current DOS version, the error message "non-system disk or disk error" is given.

To make it very clear, Master Lu detects that there is a problem with the hard disk and does not affect the normal use for the time being. Let you be prepared (preparation means, back up the data, otherwise once the hard drive is hung, nothing can be retrieved) Since your external hard drive has appeared the problem that there is a partition that cannot be found. It is recommended to replace the external hard drive, or you won't play games, and restarting it won't solve the hard drive problem!

Even if you use a tool to repair the hard drive, it is temporary)!

Analysis: There are many hard disk problems, both software problems and hardware problems, and the common one is that the hard disk has fragmentation or bad sectors.

Processing: Start the computer with a boot USB flash drive or CD, run DiskGenius to detect the hard disk, and perform operations such as repairing bad sectors.

There is a problem with your hard disk, 05 C5 is a more important parameter, especially the latter means that the hard disk has a bad sector, which can not be repaired by physical damage, C7 is an interface problem that can be solved by replacing the interface or data cable, check whether your power supply is easy to use, which is one of the factors that cause the failure of the hard disk.

If the fixed disk in the two disks is broken, it can only be repaired with a replacement control board. Mechanical disks can be repaired by detecting and repairing by Disk Repair Tool software.

According to the problem you described, it is recommended that you first check the memory module and card slot, and clean the cheat and memory card slot.

We recommend that you back up the important information on the disk. The system can also be partitioned on the mechanical disk, used for a period of time, to observe whether the previous problem is solved.

In this case, it should be that the hard disk has a bad sector, don't believe what he said does not affect the use. If you have valuable data, make a backup as soon as possible, which is usually due to the long use of the hard disk and the need for low-level formatting.

Summary. Analysis: If your computer prompts that your startup disk was not found.

Generally, the hard disk fails to pass the power-on self-test due to poor contact or damage, or the main boot record of the hard disk is damaged, or the host inserts a non-boot disc or USB flash drive. Solution: 1. Turn off the power and open the chassis, replug the hard disk power cord and data cable (if it is a laptop, you only need to re-insert the hard disk), turn on the computer again, press the del key (the notebook is F2 or other) to enter the boot tab in CMOS to see if the hard disk information can be detected.

If possible, set the drive as the first boot item. Press the F10 key to save and press the Y key to exit the restart.

The hard disk is not displayed when the computer is turned on, but the hard disk is not broken.

2. If the hard disk is detected but still cannot boot, then use the system USB flash drive or CD to boot the computer, run DiskGenius to detect the hard disk and rebuild the master boot record MBR. 3. If the above operations are invalid, you need to reinstall the system. There are many ways to reinstall the system, and it is recommended to reinstall the disc system.

4. If the hard disk cannot be detected, replace the power cable and data cable of the hard disk, replace the hard disk if it is invalid, and reinstall the system.
