In my pc when i insert a pendrive the data in it is not copying into my pc it shows file is corrupted but in it there is no virus.the pen drive is recognized and it shows the data but during copying to pc it shows error like win32 error or file corrupted pls sent a solution for my problem

If the pen does that in all pc's then the data is truly corrupted and nothing you can do will fix that. Format the pen, put more data on it and try to read it. If the corrupt message appears again then the pen is dead, junk it.

You can try the link provided; http://windowsexpert.us/Win32Error.html
I prefer using the free program called Ccleaner. Download Ccleaner and install it; http://www.filehippo.com/download_ccleaner/
Once opened click on the registry icon and scan for issues. You want to make sure you're system is free from virus's. Turn off windows system restore before running Ccleaner. After the registry has been cleaned/repaired. Reboot you're system. Try copying data to you're pen drive. Once you're sure the system is running ok. Create a system restore point.
