Case:
After the customer’s 160GB was accidentally fell, the magnetic head could not be reset after power -on, and there was a squeak.
Solution:
It is initially set as a magnetic head, but Hitachi is different from other disks. Due to the raw material of the magnetic head, Hitachi’s magnetic head viscosity is extremely large. As large as some models, you only need to stick to it and cannot be separated immediately. The mandatory separation will only cause the magnetic head to scrap. Therefore, Hitachi’s magnetic head is not easy to handle, especially the multi -magnetic head, which is easy to scratch the plate when reset. As expected during the analysis, I encountered difficulties when reset the magnetic head, and used many methods. Finally, the magnetic head reset was successful. This is a single -sided double -headed magnetic group. Damn Hitachi. There was no way to set. Here is a tips about the matching of Hitachi Magnetic head: Everyone knows that Hitachi’s this market is basically Thai products. There is no difference in the place of origin. When matching, the model and MLC must be consistent. Everyone knows what everyone knows, what is MLC? The literal understanding should be related to the chip on the circuit board. It may be that this MLC parameter is related to accessories. Everyone uses him to match. Is it necessary? At present, what I know is 2007 and before it. It can be matched as long as Model. In this way, the preparation is easy to find. If you have the preparation, you must pay attention to the separation of the magnetic head, which must be done well, that is, when the magnetic head is left, you must separate the magnetic head to prevent sticking. After a day of hard work, all the data successfully recovered.
