It could be a ram or flash problem which might explain why it partly works. However as I mentioned, do you eject the USB stick before unplugging it? Failure to do this could cause all your image flashes to fail in the same way.

Well, that depends on whether or not you've enabled or disabled write caching on the USB drive. On modern windows PCs it's disabled by default so you should normally be able to unplug safely without ejecting as you say. However, it can be enabled (sometimes by other software; not by the user), so it's always safer to eject - just in case. Bitter experience has told me so on a fairly modern Windows 7 PCAs long as you are not actually writing to the stick at the time there is no need to eject it for modern OS's.
