I have a new kindle touch but windows 7 recognizes it as a device with no drive letter and vista/win 2000 ask me to format the drive. I can't copy anything from the computer at all.

It allowed me to connect one time from the Vista computer but after I registered it changed something.
When i looked the kindle up under manage drives on my computer, it isn't an NTSF drive which is what windows systems look for. It showed up first as a FAT32 drive and then as a RAW drive after I registered and the ads started popping up on my screensaver.
I'm getting a replacement one but just wondered if anyone else has had this issue? My husband just got his and it connects just fine.
