Unable to paste onto USB Flash Drives and SD cards

My laptop is not letting me copy anything onto USB flash drives. I'm using windows 7. I have already tried system restore and uninstalling the drive in Device Manager and Disabling write protection in the registry but to no avail. I am able to format the pen drive and also access files on it and copy files from it. But I am not able to paste files from my laptop onto the pen drive. It says "Destination folder access denied" and "You need permission to perform this action". I am running an administrator account. Also I am able to do everything normally in the case of a external HDD but again face the problem when trying to paste something to SD cards. I have taken ownership, run as administrator and also tried to drag-drop but to no avail. This not for just 1 particular file/folder. I am not able to copy ANYTHING to the USB and at the same time I am able to copy ANYTHING to the external HDD. Any solutions/suggestions?

That sound like a virus doing. Did you scan with antivirus program? Or for malware? I use Malwarebytes which is good.
If you don`t have antivirus program you can try online scan engine like that from eset > Free ESET Online Antivirus Scanner

are you connected to any domains?

Scanned it. And I'm not connected to any domains. Still no result.

i hate to say this but u may have to do a clean install of windows...

Hi,
I am having a similar problem. I can copy files from my USB drive but cannot paste anything in it. The flash drive is running perfectly fine on other computers .
While pasting files It gives an error "Destination folder access denied , You need permission to perform this action" I have tried a full system scan, but to no avail . I am the only user on this laptop so there is no problem of Administrator rights. Please help
