I m a newbie and asked how to fix hard drive bad sectors

To be correct, there is no "physical" and "logical" distinction between hard disk bad sectors, and there is no such distinction in the domestic hard disk technology forum!

The bad sectors of the hard disk can only be shielded and cannot be repaired. If there are few bad sectors, you can shield them with an efficiency source, so that the system will not be able to find them. If there are too many bad sectors and they are concentrated in one place, then you can divide it into a zone and then block out the zone!

I used this method to shield the hard drive with bad sectors, and I will use it for more than 2 years.

The efficiency source is good.

However, for now, the logic bad sector is still easy to fix. Physical ones don't work. That's where professional equipment comes in.

If the hard disk is used for a long time, there will be bad sectors, and its life is also greatly reduced, if the system is reading the data in the bad sectors, it will appear stuck, and even cause downtime in serious cases, if the hard disk bad sectors are in the position of the system files, this may cause the consequences of not being able to boot, so we want to ensure the life of the hard disk, we must repair the logical bad sectors, read below to understand the method of using diskgenius to repair the logical bad sectors of the hard disk.

There are two types of hard disk bad sectors: physical bad sectors and logical bad sectors. Physical bad sectors are permanent damage and can only be isolated and cannot be repaired, while logical bad sectors can be repaired, and their bad sector errors are caused by software, as long as the sector is repaired.

Hard Disk Bad Sector Repair Steps:

1. Click the menu item "Hard Disk - Bad Sector Detection and Repair", and the program will pop up the following dialog box:

2. Please first select the hard disk you want to check and set the detection range (cylindrical range). Click the "Start Detection" button, and the software will start to detect the bad sectors. When bad sectors are found, the bad sectors are displayed in the dialog box. As shown in the figure below:

3. When bad sectors are encountered during the detection process, the detection speed will be slowed down. After the detection is completed, the software reports the number of bad sectors detected.

4. After the test is completed, you can save the test results to a text file by clicking the "Save Report" button for future reference. You can also click the "Save Detection Information" button to save the detection results as a file in a custom format of the software, and click the "Read Detection Information" button the next time you want to view it, and the detection information can be displayed on the current interface.

Important note: Bad sector repair will destroy the data near the bad sector! If possible, be sure to make a backup of your disk data first.

If there is important data stored in the bad sector area, please do not use this function to repair the bad sector, but should send the hard drive to a professional data recovery center to recover the data. Bad sector repair destroys data, not recovers it! In addition, it should be noted that not all bad sectors can be repaired, and the types of bad sectors that can be repaired by this function are limited.

For data security, it is recommended that you no longer use disks that have bad sectors. Even if the bad sectors have been fixed. In particular, don't store important data on it.

6. If you have not carried out bad sector detection, or have used other software to detect bad sectors before running this software, in order to save time, you can also directly use this software to repair bad sectors without detection.

7. If the repair is successful, hover the mouse over the cylindrical square, and the prompt will show "Fixed"

8. The repair is completed, and the software reports the number of bad tracks that have been repaired. Please actually check the repair results.

After using the computer for a period of time, most people will find that the computer is getting stuck the more they use it, installing and running more and more programs, and ...... more and more documentsAll of these can slow down your computer severely. Generally speaking, we choose to optimize the computer or upgrade the computer configuration to save it. However, if you want to have a significant performance improvement, of course, you need to upgrade your computer configuration directly and quickly.

Many people have a misconception about upgrading their computers, thinking that upgrading will upgrade all the hardware, but in fact it is not necessary. Before upgrading the computer, we must first understand the principle of upgrading, and divide the priority, which can save a lot of money. Today, I will introduce to you the precautions for upgrading the SSD and memory of your computer.

Let's take a brief look at how a computer's data flow works

The overall speed of computer parts is sorted according to the following speeds:

Processor >> Memory >> Hard Drive.

Upgrade principle: 1. Priority is given to replacing the SSD. Anyone who knows a little bit about computers knows that solid-state drives have the most significant effect on improving the speed of computers, and are the most direct and effective way to deal with slow computers.

2. If the memory capacity is insufficient, consider upgrading the memory module. You can bring up the resource monitor in the system's task manager, where we can see the memory and processor usage of the computer, and then use this to determine whether it needs to be upgraded.

As can be seen from the figure above, the capacity of 8G is completely sufficient now, and only 47% is used, indicating that there is no bottleneck in the memory, and in this case, the upgrade of the memory will not feel the improvement, so there is no need to upgrade. A memory is hundreds of dollars, isn't this saved?

What kind of scenarios are memory & SSD upgrades suitable for?

How to choose to upgrade SSD and memory for your computer? Actually, it still depends on the need. According to the general experience: memory upgrade is mainly suitable for running large programs, if your computer is only used for work and study, it is recommended to add memory.

SSD upgrades are more common in scenarios where the read and write speed of a large amount of data needs to be improved, such as:

2. When switching between game maps, I found that the loading speed of the map was slow.

To sum it up, it is still the classic saying: if you want to be super-god, you must be solid. (provided that the processor is sufficient, and the memory is sufficient).

The upgrade process requires the following points to be aware of.

Memory. Before upgrading the memory, you need to understand the specifications of the memory, including the generation, frequency, single bar & maximum capacity, high and low voltage, compatibility, etc.

Today, DDR4 is the mainstream memory, and for some older computers, DDR3 memory is still used. And if the computer is still using the eliminated DDR2 memory, which is almost a classic machine, decisively change to a new phone, it is not recommended to upgrade.

It should be noted that DDR3 and DDR4 memory are not compatible with each other, that is, DDR3 computers can only buy DDR3 memory upgrades, and vice versa.

It's not that this can't be done, that is, the logic is wrong, and it may need to be redundant and not used up.

Use diskedit, locate the wrong sector, write all ff or all 0, and then find that it is normal. A few sectors are easy to say, but if there are more, it will not become, and if you calculate it, you have to ......Years ......

Then you can take a look at HDD, under DOS, that time it was all written bad, and then it was all cleared, and the result was really good. It's just a book that fell. Hehe, but it's been a long time, a few days ......
