Problem SanDisk Cruzer Slice 16GB - Win7 64bit

My Problem is, that when I plug in my SanDisk Cruzer Slice 16GB into my Win7 64bit Desktop PC many times nothing happens and sometimes the Stick gets recognized with 0 Byte.
I have tried to use the USB Stick on other Systems(Win XP 32bit, Win 7 32bit) and there it works fine.

I tried to google this problem and it seems that many people experience this Problem, but i couldn’t find any solution. I have already tried to reinstall the driver.

Does anybody know a solution? Please help me!

I suspect unplugging the device without doing a Safe Removal is corrupting the device’s FAT.  Make sure you always have backups of your important files.
