Hello to all people

Does anyone had experience with Fujitsu MHT2040AT , my case have PCB problem, im know MHN2, and MHM2 use adaptive Data on PCB; does anyone know if model MHT2040AT use adaptive data on PCB?
.
Im try exchanging PCB directly, use same FW version , and same PCB Code, same model etc, electronically are same, microcontroller model, Same ROM , etc. physically its same so im turn on and disk spin and send DRDY DSC;

but i cant heard the recalibration sound, the heads never was launched from the landed zone to the platter´s , im try to access sectors, and when try to access Send ERR ABRT like SA problems but this is caused, because MHT use Adaptive Information wich need to be transfered to Donnor PCB? or could be a Head problem, ?


Thanks for all u help

did u try transfer ROM chip from original pcb to the new pcb .

Try using repair station from a-ff.com, it has a diagnostic mode which you can use free to diagnose the disk. Symptoms could mean firmware is damaged.
