Pen drive doesn't show the data even when data exists,

Hi Friends,

We can use below steps to get over the mentioned issue.
for this we need to open Command prompt,
We can open command prompt by typing CMD on start menu.

Here i assume your Pen-Drive letter as J:
enter the below command in Command Prompt.
attrib -h -r -s/ s/ d J:\*.* Press Enter

Note : Replace the letter J with your Pen Drives letter.

Try this, it works in 90% cases
First of all check if the files are not in hidden mode..
Click on "start" run type cmd and then press enter

(attrib space -h space -s /s space /d space /d space J:\*.*) enter
please not do not type space where i have mentioned space it's just a black area. means you need to give a space between the commands using space bar.




now check the pen drive..:) i know it's working now. :)
