  1. USB drives from good manufactures seldom go wrong. The most common reason that drives of this size go wrong is because it is a fake drive. When drives of 512MB were made there were a lot of fake drives produced with only 256MB or less. Fortunately the problem nowadays is a lot less common but you still get drives from China that are fake. To cure this problem you will need to low level format the drive with its manufactures utility. The manufacture of the drive will be different to the one it pretends to be. Your controller probably is i5062-ZD which is the most common controller that fake drives use and you will have to use pdx8_2k_320.zip to reformat it. Visit this web site for more information.

  3. I would open up the drive and check on the controller fitted and see how much memory is actually there. I suspect based on the PID you gave that you have a SM3255AC controller (check this) I have been unable to find a formatting utility for this. Looking on the web there are a lot of fakes based on this chip.
  4. Is it worth bothering with this drive as it is only 512MB. You can get much larger drives nowadays for not very much money.
