Analysis on the solution of slow reading speed of notebook computer hard disk

Netizens reported that the reading speed of his computer hard disk was very slow. What's the matter? Then let me tell you about the solution to the slow reading speed of laptop hard disk, hoping to help you!

Solution to slow reading speed of notebook computer hard disk;

Many computer users report that their hard disk reading speed is very slow, which not only seriously affects their computer work efficiency, but also seriously affects our working mood. What should I do if the reading speed of computer hard disk is very slow?

Let's take a system disk as an example to clean up the disk fragments of the system disk. You can clean up all the fragments of each disk!

Step 1: Right-click the system disk, and then click Properties.

Step 2: In the general options, we click Disk Cleanup! The computer will show that it is calculating how much space can be released!

Step 3: We select the files that need to be cleaned and delete them! In the general options, we can choose to delete unused programs!

Step 4: Click Disk Defragmentation in the computer properties tool!

The disk contains virus files.

We use antivirus software to thoroughly disinfect the disk!

There is a bad hard disk.

Let's download HD tuning software! Baidu search, just download a release!

We run software. Test the reading speed of the hard disk first. If it is normal, the hard disk is fine, but if the reading speed is low, we consider that the hard disk has a bad track!

Next, we scan for errors. If there are bad tracks, the software will detect them!

You can separate the bad track area of the disk, which can alleviate the problem of slow disk reading speed, but I suggest you change the hard disk or repair it!

Analysis of the solution that the computer can't read the mobile hard disk.

The 1.CMOS parameter is not set to ON. For friends who have never used a USB external device, even if the driver is installed correctly, the system may not be able to detect the USB hard disk. This is mainly because the default CMOS port of the motherboard is closed. If it is not set to on, Windows naturally cannot detect the mobile hard disk.

To solve this problem, we can restart, enter the CMOS setting window, and set the item "Assign IRQ to USB" to "Enable" in the column of "PNP/PCI configuration", so that the system can assign available interrupt addresses to USB ports.

2. Insufficient power supply of the computer Because the USB hard disk also needs to consume a certain amount of power when working, if the power is obtained directly through the USB interface, it is very likely that there will be insufficient power supply.

Therefore, almost all mobile hard disks are equipped with independent external power supply or PS2 adapter, which is powered by keyboard. At this time, as long as the external power supply is connected in advance or the keyboard is connected through the PS2 adapter, try again after ensuring sufficient power supply for the mobile hard disk. You should be able to use it normally at this time.

Need to remind everyone that it is recommended to ensure sufficient power supply before using the mobile hard disk, otherwise it is likely to damage the hard disk due to insufficient power supply.

3. In addition to the above two reasons, the failure of USB extension cable may also be caused by the mismatch of USB interface types, which makes the mobile hard disk unusable. For example, the USB interface configured by the computer is 1. 1 standard, and the purchased mobile hard disk is USB 2.0 standard interface, which requires that the cable connecting the computer and the mobile hard disk must support USB 2.0 standard.

Because high-speed mobile devices are plugged into low-speed hubs, they may not be installed normally. Some friends use USB flash drives while using mobile hard disks. For convenience, they directly use the USB 1. 1 standard cable attached to the USB flash drive, which makes it impossible to correctly identify the USB 2.0 standard mobile hard disk. This fault can be solved by replacing the connecting cable with USB 2.0 standard.

4 4. Improper system settings For some users, after installing the driver, they can view the icon of the mobile hard disk from the device manager, but there is no corresponding drive letter identification in the resource manager, which is caused by improper system settings.

Double-click the mobile hard disk icon in Device Manager and click the Properties button in the pop-up window. At this point, you can see four options: disconnect, delete, synchronous data transmission and Int 13. By default, the Deleteable option is not selected. Check this option and restart the computer. You can see the newly added mobile hard disk drive letter in the Explorer.

Analysis on the Solution of Computer Unable to Read Mobile Hard Disk II

There are two cases where the mobile hard disk is not displayed and cannot be recognized on my computer:

1. After the mobile hard disk is connected to the computer with a USB cable, the system prompts that it is unrecognizable or completely unresponsive.

This situation is generally caused by insufficient USB power supply. If the mobile hard disk is connected to the front panel of the computer case through a USB cable, please insert both USB plugs of the USB cable of the mobile hard disk into the USB interface of the front panel. If it is connected to the USB interface of the motherboard behind the chassis, connect the first USB plug of the USB data cable of the mobile hard disk, otherwise plug both.

This situation may also be that the hardware of the mobile hard disk is damaged or there is something wrong with the USB driver of the system.

2. After the mobile hard disk is connected to the computer with USB cable, the icon of new hardware will be displayed in the lower right corner of the computer. But when I turned on the computer, I couldn't find the drive letter.

In this case, you can see the mobile hard disk in Disk Manager. Solution: Right-click My Computer, select Manage, then click Disk Management to see the drive letter of the mobile device, right-click to change the drive name and path, and click Change in the pop-up window to specify the new drive letter of the mobile device. Click OK. If your mobile device has multiple disks, please repeat this operation several times.

If you still can't see the mobile hard disk, just restart the explorer.exe process or restart your computer.

How to restart the explorer.exe process: Press the computer's soft start shortcut key CTRL+ALT+DEL, and the task manager will pop up. Click the Processes tab, locate the explorer.exe process, and then click End Process. The desktop and taskbar are gone, don't worry. The next step is to create a new process. Click the Application tab again and click the New Task button below to find the explorer.exe process of this path. C:WINDOWSexplorer.exe (C: represents the disk where your operating system is located, which can be changed according to the drive letter installed in your operating system) and then click OK.
