    Hi Daud and thanks for the infoe, it is very useful.

    Just one more question regarding step 5 if i may:
    "Step – 5 Resolder all components around the connector and controller chip. Especially check fuse type of resistors. Sometime the value of resistors increases."
    should i check only resistors or also capacitors?
    how do i know that a value i read is faulty?
    what should the good reads and bad reads look like?

    Thanks mate,
    Oded

    Hi Oded !
    You should check resistors especially. however chances of capacitors fault are very low. value of resistor is marked on it.
    thank u for reading this article.

    hi daud
    1st thanks for post

    if my USB show capacity 8 GB but my pan drive real capacity only 2 GB how cam i find this problem

    1. Daud Asi says:

      Hi Kamal !
      Variation in capacity is the fault of controller IC. It should be replaced.

    Hi,
    I have a 16GB USB Kingtston Data Traveler, it's very similar to yours in the pictures.
    Connector seems good, please could you tell me if there's any way to test a single component before desoldering it ?
    Thanks in advance.
    Alessandro
