1, hard disk maintenance tools and materials:
Hard disk maintenance needs some professional tools and materials. The following are some necessary tools and materials:
Screwdriver: A screw used to unscrew the neck of a hard disk.
B, cooler: used to prevent the hard disk from overheating, resulting in data loss.
C data cable and power cable: used to connect the hard disk and motherboard.
D. Card reader: used to check and transmit data in the hard disk.
E. Disk rescue tool: used to detect bad tracks on the surface of hard disk and try to recover data.
2, hard disk maintenance steps:
A. Slow reading and writing speed of the hard disk: It may be caused by a large number of junk files in the hard disk, poor heat dissipation and wrong partition of the hard disk. Solution: clean up the junk files in the hard disk, repartition, replace the hard disk radiator and other methods.
B hard disk is unrecognizable: it may be caused by loose hard disk interface, damaged hard disk firmware, damaged motherboard interface, etc. Solution: Reconnect the hard disk interface, brush the firmware and replace the motherboard interface.
C. The hard disk appears blue screen or crashes: it may be caused by data damage and virus infection in the hard disk. Solution: Use disk checking tools to check and repair the data damage in the hard disk, and remove the virus through antivirus software.
The above are some common hard disk failures and their solutions. When repairing the hard disk, please be sure to choose the corresponding operation steps according to the actual situation of the hard disk.
3. Basic knowledge of hard disk maintenance:
A. Hard disk types: At present, the commonly used hard disks are traditional mechanical hard disk (HDD) and solid state hard disk (SSD), with different working principles and different processing methods.
B. Structure of hard disk: The hard disk consists of disk, magnetic head, motor, controller, etc. Knowing the structure of hard disk can help us to judge the problem.
C. Interface of hard disk: Hard disk interface usually includes IDE, SATA, SCSI, USB, etc. We need to know the types and characteristics of hard disk interfaces.
