Appendix B. Hard Disk Motor Driver Chip Pin Resistance Worth (also called Resistance Value)

https://penzu.com/p/fd7fbd51 is definitely the most vulnerable chip inside the challenging disk circuit component. About free data recovery software of your challenging disk circuit failures are caused by this portion. Irrespective of whether the motor drive chip is damaged is usually roughly judged by the resistance value from the pins about the chip to the ground. Table B-1 is actually a table of reverse resistance values ​​of every pin from the common new table challenging disk motor drive chip to the ground, utilized to confirm no matter if the motor drive chip is damaged. The information test utilizes a digital multimeter, the red test lead is grounded, and also the black test lead points to the pin under test.

For any chip with pins on only two sides, the pins in the counterclockwise path starting in the initial pin are represented by two columns of numbers, where the very first column indicates the resistance with the initially side and the second column indicates the second side Resistance.

To get hard drive data recovery software with pins on all 4 sides, the pins within the counterclockwise path in the very first pin are represented by 4 columns, exactly where the initial column indicates the resistance in the first side plus the second column indicates the second The resistance value of the surface, the third column represents the resistance worth of the second surface, and the fourth column represents the resistance worth of your fourth surface.
