This error comes when you have an application which is running from your pen drive or may be some file or document opened from your pen-drive when you are removing your drive. In short, some file on your pen drive is in use by some other program on that computer. So close all such files or applications and try removing the drive. Or Install "UNLOCKER" by clicking the link below http://www.troublefixers.com/problem-removing-pen-drivenot-able-to-remove-pen-drive/

Yes you can do that. you copy files to your cd to your pen drive and then run the applications .exe file.
But there are some instances that you cannot copy a file from cd to pen drive or even to computer.
This instances is caused by CD that is copyright protected. it means that the files of the CD is not allowed by the Producers to be copied. Also, if your CD is bootable, when you transfer the files to a pen drive, your files will not be bootable anymore.

Hope my solution helped. Thanks for using fixya!

If this is a U3 Sandisk USB stick drive you can usually use the launcher installer to backup the contents if it is still physically working.
Otherwise there are a few websites that will offer a recovery application

You might need to get winrar from http://www.rarlab.com/

Now remove the pen drive and plug it back in to the USB slot, Now open my computer and try to create a new folder in the pen drive, you can't. You get an error. That's what you wanted right? :-)

- I think you have compatibility issue, Check if the software on your pen drive supports pdf file

I presume you are trying to open the document using the Recently Opened file list in Excel's "File" menu. If so, use the "Open" entry in the "File" menu instead and navigate to the pen drive from there - it may be that the drive letter has changed. Another possibility: use Windows Explorer (which can be accessed by double clicking on My Computer) to copy the file from the pen drive to the desktop and open it from there by double clicking on it. If that still doesn't work (but the copy worked OK) then right click on the file, click on "Properties" and see if the Read Only box is checked. If so, uncheck it.

And yet another possibility: after closing the file, did you pull the pen drive from the PC without telling Windows to eject it first? If you just remove the drive too quickly, without ejecting it first, the file can easily be corrupted.
