I have a Zenithink ePad with an 8GB MicroSD card for music and pictures. When first set up the ePad scans the MicroSD card for music/picture files and catalogs it but each time it's removed the device has to re-catalog the items. Therefore when I want to add new media/install new apps/etc I want to simply load them from my USB or via WiFi. Questions 1: Is there a way to "safely eject" a USB. I see the option to Safely Eject the SD Card that is mounted but not for USB. Each time I remove USB I get an error saying the USB (Udisk) has been removed unexpectidingly and the music/photo app has to re-catalog everything Question 2: Is there a way I can copy the files over via WiFi (from my desktop to the device) so I can avoid this error?
