Ok, boot ur system in safe mode. Open any folder and click on tools->options->view tab->check 'show hidden files and folder, clear hide system files. . . . .'-> apply -> close the folder & right click on drive that has problem & click on ''browse''. See if there is autorun.inf, if found, delete it. . . .clean ur registry with Ccleaner & restart ur system.
It sud work fine.
