Thanks, but it doesn't work for me. The 1GB USB flash memory still freezes the pc and can't format with vista x64.

1016 --->Desktop? 1009 --->Laptop?

I have a similar problem in vista x64 ultimate. The OS recognizes the USB flash memory (1GB) and installs the driver, but it is very very slow transferring files and it freezes if you try to transfer several big files at the same time (drag&drop). I have to unplug it for the OS to respond and then I can't do a full format because it freezes too. The same USB flash memory works perfectly in XP sp2 (other laptop compaq 2540ea). I have another USB flash memory that works well in both laptops and OSs (HP dv9063ea-Nvidia Geforce Go7600....). I have the OSs updated.
