Try to attach that pen drive in another slot and if its work fine than always use that slot.

If its not working fine or showing that malfunctioned error than please update your USB driver of your machine.

try other usb port, or other computer and see whether the hdd is detected. If still not, try to go to device manager ( http://www.computerhope.com/issues/ch000833.htm ), and then assign a drive letter to the hdd. After that, try to access it from Computer, if not able to access it, format it (use quick format) and then use this data recovery program to recover your files.

4 Gb pen drive can't poen


Your drive could be corrupt. The first thing I would do however is make sure you are plugging it into a good USB port. If you are using a desktop with USB ports in the front, and are plugging the drive in there, remove it and plug it in to one of the USB ports on the back of the computer. Many times the front ones will have issues with certain USB devices. If that doesn't work, you very well may have a bad usb drive. I would try it on another computer if switching the usb port doesn't help, to see if the drive is truly not working or just a driver problem on your computer.

I m not being able to copy mail massages from


By a pen drive I'm guessing you mean a USB flash drive like thing. When you plug the pen drive in, your computer should automatically detect it and open up a window that has its contents. Leave that open and find the file that you need to move onto it and just drag and drop it into the Pen Drives window. Its as simple as that. Then close the window and disconnect the drive.
