Dear Friends I want to know how can I check Desktop hard disks PCB (WD /Seagate particularly). I also want to know which is best pocket multimeter for accurate checking ( for onsite field testing) Design of all pcb's is different but there will be standard common components like diode or voltage regulators or fuse etc . This will help me to give to new technians and for myself as well. Thank you. |

I wrote several tutorials on the subject at the HDD Oracle, but the resource has now become essentially unusable. As for multimeters, any cheapie will be more than adequate. |
