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!
