My dad builds computers. He gave me a newly built computer 6 months ago and the hard drive went out today. I lost 6 months worth of pictures and work documents.<br /><br />The hard drive is fried.

The case doesn't fit. It is very close, but three friends and I couldn't even get it on. So the top is just slid on, and the bottom isn't on at all.

I have 3 of these, and even with new batteries and up to date software each one has manifested a problem. I can not get them to work smoothly. The are jittery and sometimes completely quit. I need to spin the ball to get it to start working again. In gaming, this is death.<br /><br />Never had this issue ever with the wired red ball version, but Im not buying any of these after being a loyal Logitech Trackball user since the original white model came out.
