Why can't I copy files from Computer to Flash on Passport?

Hey friends, its a problem i struggle, since i got my passport...
When i copy files from my Computer to the Flash Z: it copies with 0 Bytes... i dont know whats goin on..

Are you just dropping them in to Root "Z" drive??

Open up the Z Drive (click on the little plus sign or triangle for win 7 up users), and drag/drop into the appropriate folder Music, vids, docs etc....

yes i drag and drop it into the folder Music, but it doesnt load, ive never experienced such a slow process never, i have no Clue whats goin on maybe its software problem or hardware i dont knoe. :/ If i copy into the extern micro sd it loads with 20 mb/s but on the device storage as you can see with 0 bits.. very sad

Have you used the ext sd card in a bb device before? Some folks have had issue with some memory cards just not working quite right....

Yeah i have a 16 gb SanDisk Micro Sd in my Passport, but i copy my music into the device itsself, because i Encrypted my Sd Cards
