The exact same thing happened to me around 3pm EST yesterday. Everything is gone. Music, pictures, video, EVERY-*BLEEP*ING-THING. I had pictures and video of my nephew from about 3 months to 15 months. His first steps were *bleep*ing on it. I'll be ripped if I don't get that back.
I tried everything. I turned it off then on (didn't work); turned it off, took the sd card out, put it back in and turned it on (didn't work); turned it off, took the battery out, put it back in, turned it on (didn't work); turned it off, took the card out, took the battery out, put both back in and turned it on (didn't work); took card out while on, put it back in (didn't work); I even tried it in my friend's Sprint HTC Hero and he couldn't locate anything. I'll try putting it in my computer when I get home from work.
The thing that floors me is that my backgrounds and contact pictures are still showing. Its there. I *bleep*ing know its there. I'm bringing it to Verizon tomorrow.
And it kills me that I was singing its praises over the Moto Droid all weekend at X-mas parties. This is a huge punch in the gut.
