What to do when the computer starts to read the hard drive
Computer boot does not read the hard drive solution one:
1 Hard drive data cable or power cord interface loose.
2 The hard disk SATA interface standard is higher than the motherboard interface standard.
3 Hard drive data cable damage (see more).
4 hard disk circuit board failure or hard disk partition table damage.
Workaround:
Shutdown for possible factors and solutions
1) Plug the data line power cord.
2 Use the same hard drive as the standard.
3) Replace the data cable.
4 Repair the hard disk circuit board or repair the partition table.
Computer boot to read the hard drive solution two:
Computer hard disk Failure Analysis:
The boot can not detect the hard drive, there may be data cable damage, hard drive, bad, poor interface or power supply is insufficient.
Computer hard Drive Troubleshooting:
1, first to exclude a new data line, and the hard disk installed after the restart of the computer, self-test detected the hard disk, and the normal access to the system, but the system soon ran suddenly panic, and prompted the hard drive read errors.
2, restart the computer, run HDD scan software into the main interface, and then click the "Start" button-year-old hard drive for scanning.
3, scan the completion of the scan results will be a legend in the form of the right side of the interface, the figure shows that the hard drive does not exist any bad.
4, restart the computer failure is still, at this time suspected power supply D line plug voltage is insufficient, and then use the Multimeter Test D line power supply voltage.
5. First measure the voltage between the yellow and black lines corresponding to the pins, the multimeter will be adjusted to 50V, and then the black pen inserted into the line of the wire corresponding to the pin, the red pen inserted into the corresponding pins, at this time the measured voltage is +12v, indicating the yellow line and the voltage between the ground is normal.
6. The voltage between the red line and the black line corresponding to the pin is measured. In order to measure the accuracy of the need to adjust the multimeter to 10V, and then insert a black pen to the corresponding pin, the red pen inserted into the corresponding pins, the voltage measured at this time is +5v, indicating the voltage between the red line and the ground is normal.
7, to sum up that the power supply can be normal power.
8, will be inserted in the optical drive power cord and plug in the hard drive of the power cord exchange, and then the boot found all normal, but open the "My Computer" window, found that the optical drive letter is missing, so you can determine the original hard drive power cord problems.
9, carefully observe the problem of the power cord and its D-type plugs, found that the D line Plug 4 column joints rich in a layer of yellow dirt, and then the tweezers with a dip dipped in alcohol absorbent cotton balls will be removed from these yellow dirt.
10, the optical drive will be connected again, restart the computer CD-ROM is successfully detected, so that the fault is completely resolved.
