Compatibility?

It won't work with acer d257-13450 netbooks. I tried on two different ones. The system freezes up. Nothing I did seemed to fix it. I ended up using it in another laptop. It works fine in it. I think there is a flaw in the firmware. Go do the research before you buy it. There are other cases of their drives freezing up on certain systems. When it does work, it seems to work well.
