Recently, through software testing, I found that my hard disk read and write speed has become very slow. The hard disk read/write speed is slow. It may be a problem with the system. The hard disk has bad sectors or other causes. Let's take a look at how Xiaobian can solve the hard disk read. A write slowdown. 1. First enter the system to clean up the junk files in this disk, click the “Start” button, and select “All Programs” from the pop-up “Start & rdquo; menu” <;All Programs”→“Accessories”→ “System Tools”→“Disk Cleanup” menu item. 2. Then pop up the “Select Drive” dialog box, select the drive to be cleaned in the “Drivers” drop-down list, select the “C:” option, and click the “OK” button. 3, then pop-up "Disk Cleanup" dialog box, the disk cleaning software began to calculate the space that can be released in the C partition. 4. When the calculation is completed, the “Clean Disk Cleanup” dialog box will pop up, and then select the file to be deleted check box in the “Delete Files to Delete” list. Select “Internet Temporary Files” and “" ; recycle bin & rdquo; & ldquo; temporary files & rdquo; check box. 5. Click the “OK” button to pop up the “C: Disk Cleanup” dialog box, then click the “Y” button to bring up the “Disk Cleanup” dialog box to start cleaning the selected files. , the dialog will automatically close after cleaning. 6. After cleaning up the junk files, the read and write speed of the hard disk is still very slow. At this time, you can use anti-virus software to detect whether the system is infected with viruses. 7, after testing, the system is not infected with the virus, so you should find the reason from the hard disk itself. 8. Run HD Tune software to enter the main interface, then check the data transfer rate of the hard disk, and find that only 3.2MB/s, switch to the “Error Scan” tab, click the “Start” button to scan the hard disk, the result is not Found any bad sectors. 9. At this time, you should suspect that there is a problem with the hardware. Remove the hard disk from the chassis and observe it carefully. Check whether the hard disk interface and the circuit board are damaged. It is found that the pin of the hard disk IDE interface has a stuck, and it is preliminarily determined that the fault has a pin sag. caused. 10. Use a hex driver to remove the hard drive's circuit board from the disk, and then use a pair of tweezers to gently pull out the pin that is recessed in the IDE connector to restore it to the position. 11. Use a soldering iron to solder the connection point between the needle and the board. Do not solder the solder to other places while soldering. 12. Re-fix the circuit board to the disk, and correctly install the hard disk into the chassis, restart the computer, and read the data again to find that the data read and write speed has returned to normal. After determining that the hard disk read/write speed is slower because it is not caused by software, we must suspect that the hard disk read/write speed is slow due to the hard disk's own fault.
