What if the computer hard drive smoke is damaged?

When a computer is running, reach out to the chassis to Bola and Debug. Sudden see the hard drive out of a white smoke, and then look at the image on the monitor is motionless, is apparently dead. Reseat the power after the boot is a black screen. At this time with fingerprint hard disk can feel the disc body has a slight vibration.

After calm down, decided to try to repair their hard drive.

Analysis as follows: Since the power-on after the hard disk body has a slight vibration, the estimated hard disk has no physical damage, the hard disk power supply condition is normal, hard drive spindle motor is certainly not bad. Then the boot black screen is likely to be the hard disk circuit board has a problem, a white smoke must be burned what components, so that the motherboard and hard drive information exchange channel Open, the CPU does not detect the hard disk stored information, nature can not boot.

After the idea of clearing the hard disk circuit board, did not see any obvious burning traces. Again careful examination, finally found that the bottom of the circuit board (to the hard disk interface set as the upper end) of the SMD resistance components in a component (its label on the 1r00) on the surface as if slightly puffed up the bubble skin, a shave with a finger is lost, but there is no obvious burning mark on the component, only a metal point of the size of the needle. Use the Multimeter electric block to measure the element resistance to 128kω. And then use the multimeter to measure other signs of the same components (symbols on the components are 1r00), the resistance is 0, only this resistance is 128kω, it appears that this component is damaged. Then put the hard disk back to the computer, with a metal tweezers clip at both ends of the element, so that the short-circuit resistance here for 0ω, and then boot. At this point, only listen to "tick" a sound. The computer went smoothly into the XP system. It seems that the component is damaged.

As is in the Spring Festival holiday during the electronic city is not open, buy the same components to replace, I decided to Tuffa. A few rosin fluxes are melted at both ends of the element, and then find a single strand of insulated thin copper wire folded into the U-shaped, put the copper wire lying on the circuit board on the component, the two copper heads are welded at both ends of the element, to the element at the end of the artificial 0ω of the path can be.

In the actual operation should be extremely careful. Use a pointed soldering iron and grind your head into a ballpoint head size; welding action to be quick, unplug the electric soldering iron power plug, do not use a multiple strands of wire, in case a wire is not welded to meet other components caused by other faults; do not use enameled wire to prevent the use of the line after the day after the protection of the paint is worn off and cause other problems.
