Hi,

try running the U3 removal tool to uninstall the software from the drive which will also reformat the drive… 

Here is a link to an article with instructions to remove the U3 Launchpad

http://kb.sandisk.com/app/answers/detail/a_id/2550 (follow method 2) , U3 is EOL and most users dont require it unless you want password protection, if you wan to reinstall it here is the link - http://kb.sandisk.com/app/answers/detail/a_id/240

Whenever I insert it.It gets loaded up easily, but the moment I open it, my computer hangs up! 
But when I try to format it, then it says, “windows was unable to complete format”. 
And when I try the same thing using disk management thing, then it says that its “system reserved” and it doesn’t get accomplished… 
Please help me out… 
Thank you in advance… 
Please reply…

What version of Windows are you running?  What are you opening the pen drive with that makes the computer hang?
