Hard drive data loss! Worry! The hard drive is suddenly lost in use

Set the master and slave jumpers of the two hard disks, the first hard disk jumps to the master disk, and the second hard disk jumps to the slave disk. (If both drives are set as the primary drive, install them separately in IDE1 and IDE2.)

HDDs are traditional HDDs in which data is stored in the sector of the diskette. It is mainly composed of: platter, head, platter shaft and control motor, head controller, data converter, interface, cache and other parts.

As a precision device, dust is the enemy of the hard disk, so the air entering the hard disk must be filtered.

The head can move along the radius of the platter, and with the high-speed rotation of the platter at several thousand revolutions per minute, the head can be positioned at the designated position of the platter for data reading and writing operations. The information is written to the disk by the electromagnetic current through the magnetic head very close to the magnetic surface, and the electromagnetic current changes the polarity, and the information can be read in the opposite way.

All the platters in the mechanical hard disk are mounted on a rotating axis, each platter is parallel to each other, there is a magnetic head on the storage surface of each disc, the distance between the magnetic head and the platter is smaller than the diameter of a human hair, all the magnetic heads are connected to a magnetic head controller, and the magnetic head controller is responsible for the movement of each magnetic head.

Noise: Because the solid hard belongs to no mechanical parts and flash memory chips, it has the characteristics of low heat generation, fast heat dissipation, etc., and there is no mechanical motor and fan, and the working noise value is 0 decibels. Mechanical hard drives are much inferior.

**: As of (2014-11-23), the 128GB SSD of a common brand is about 450. And the 1TB HDD** is only about 360. SSDs are more expensive and less cost-effective than HDDs**.

Enter the BIOS, change the HDD mode to IDE mode, and it should be fine.

See if the drive options in the power management scenario are set to how many minutes to turn off, and change to never.

The hard drive is going to hang, and my Western Digital is also this virtue!

I'm the same as you, I want to ask how the landlord solved it in the end?

**Turn on the C7 is there no data and turn yellow, if there is, it is recommended to change a SATA cable (the one that connects the hard disk and the motherboard), and then how much power is rated for your power supply? What is the power supply brand? If the power supply is insufficient when the power is turned on, it may also cause the drive to disconnect.

Open HDTUNE to select the health item to see,C7There is no data and yellow,If so, it is recommended to change a SATA cable (the one that connects the hard disk and the motherboard)

It may be that the data cable or the power cord is not in good contact, or it may be that the power supply is insufficient or unstable, if your machine is full of hardware devices, try unplugging the infrequently used ones to see if there is any improvement, such as the optical drive.

2. Run the software.

Double-click the icon on the desktop or click on "Start Program Recuva" to run the software. If you are running this program for the first time, the recovery wizard interface will be launched (as shown in Figure 1), please click "Cancel" to return to the main interface of the program.

Or try. Select the drive letter, right-click - Properties - Tools - Check - Start Check - check "Automatically fix file system errors", "Scan and try to recover bad sectors".

It may be that the operating system hides your stuff when it shuts down, you can select the Select Folder option in the tool to remove the unchecked box from the hidden folder.

Reasons for hard drive data loss. Bad tracks or tiles may be damaged. It is also possible that a hard object hits the fluid conduction. The stored data of the porcelain plate is lost, and the virus destroys the guide limb and causes data loss.
