Please Note:
1.These boards are used, the circuit board components not falling, the interface did not break.
2. All PCB have been tested before shipping. If the PCB is faulty during shipping, please inform us immediately after your received it.
3. If you are not sure the PCB is compatible with your HDD or not. Please contact us
Replacement the PCB only can solve the problem that is caused by the PCB faulty and HDD failures are not always caused by the PCB faulty. This PCB is not guaranteed to fix your HDD.
Remarks: If your HDD firmware, date code and site code is different. You can swap the BIOS chip from original PCB to the replacement PCB, to make the replacement PCB compatible with your HDD.
If you need our help to swap the BIOS chip on the PCB, please contact us. Thank you.
Attention: Replacement the PCB only can solve the problem that is caused by the PCB faulty. If your HDD having the following problem:-
Symptoms of failure:
Replacement the PCB may not solve the above problem. These problem is caused by the HDD firmware corrupted.
1、We want to buy 1 each circuit board customer has certain repair technique, because some circuit board is not a change to the disk body can be directly admitted to the hard disk, the hard disk body and each of its original circuit board is one to one, that is a BIOS chip. So, must be the original circuit board (i.e. bad board) BIOS chip to get a good board, so the hard disk can be identified. Hard disk circuit board shop the sales of all annotation which is BIOS chip.
2、 what customers need hard drive circuit board, please pass the information to contact us, we will immediately help you query the hard circuit board without,immediate customer delivery. If there are special circumstances that day can not beshipped, we will contact you in time.
3 、customers before buying a circuit board determine whether circuit boardproblem! Because the hard disk failure is more complicated, and not the hard diskproblems must be board problem, some hard disk on the surface like circuit board is broken, but is actually a disc body fault, or two fault exist at the same time; thereforewe do not guarantee that after put on our circuit boards for your hard disk will benormal operation.
4 、if the customer on the hard drive circuit board is not very understanding, the hotel provides a simple technical support, try our best to solve your problems, but on therepair professional disk technology because it is not simply to say that clearly, so notin-depth explanation, please customer understanding!
