This is a rather common problem these days with many USB pen drives or thumb drives and portable USB Hard disk drives that these pen drives or hard disk drives usually don’t open or hang the Windows Explorer when double clicked. This is usually not the fault of the pen drive or Hard disk drive but the problem is more serious which – such pen drives which don’t open or hang the PC are usually infected with viruses, malwares, adwares or other malicious softwares which try to exploit the autorun feature of the USB Pen drives and USB Hard disk drives.

Most common type of viruses use an Autorun infection where there is an autorun.inf  file created which is usually s hidden system file which you won’t be able to see in Windows Explorer with default settings. You need to turn on settings to view hidden as well as system files. Such filed exploit the automrun functionality of Windows and launch a virus file or malicious file whenever you double click on the  pen drive or USB Pen Drive. In many cases, the virus might have been removed already by an anti-virus software installed on your computer or the previous computer where the pen drive or portable HDD was connected, in some cases the virus may still be on the pen drive. The reason why Windows hangs in some cases is that autorun file is trying to run a virus file which the anti-virus is trying to prevent at that time or the virus file does not exist (already deleted somehow)  but the autorun file starts some invalid file which makes windows explorer to hang. And another scenario is the autorun files which are designed to hang Windows explorer so that the computer is practically stalled for most common users. Please read some tips below which will keep you out of this mess:
