    Hi everyone
    I'm having trouble identifying a smd diode in a hard drive pcb the marking are very small and hard to read but here's what I was able to read:
    there are two of them and both have only two legs
    the first one code is: QARB48
    and the second on is: DUJZ249
    it would be greatly appreciated if anyone could help me.

    QARB48 *could* be a small signal diode (a la 1N4148)

    Best to provide a photo of the board showing the diodes.

    Why do you want to replace them?
