Although mine is only a 512, I, too, have suffered from the mysterious sandisk cruzer death. I'd only had my 512 titanium for four months, and--literally--only used it about 8 times before the disk stopped dead in its tracks and my computer could no longer "recognize" it.I, too, am being forced through hoops by the Sandisk customer service/tech people. Although I've done their "suggested reformat" steps TWICE (although it's a bit hard to re-format a dead device ;-) and told them so, some clueless tech named Kirk keeps writing back, urging me to do the same pointless rigamarole over and over and over again.Frankly, if they do not tell me where to send this pathetic piece of merchandise for a FULL REPLACEMENT soon, I'll have to wash my hands of this company (but, you can be sure I'll tell my story far and wide).Beware.
