I am having the exact same problem after installing Kies on one of my laptops window 7 .on my other laptop window 7 no issue t . I uninstalled kies and now it works again. For me I need Kies so I will just buy sony humbdrives for now on. (( PS the older version Sandisk does work with kies.)) I spent hours and hours trying to figure out how to make the 8 g sandisk work with samsung Kies but could not let me know if you figure it out. Thanks
