Hi All I'm a Newbie to Apple and I'm looking for some help. I have two pen drives. One is a 1gb and the other is a 4Gb Sandisk I have no problem getting my new MacBook to read and write to the 1Gb drive, but it will only read from the 4Gb Sandisk. While the same file can be exported to the 1Gb drive, I get ERROR unable to find file/folder if I try to export the same file to the 4Gb drive. Any answers? Also how can I rename the drives, it is easy in Windows, just right click and rename?
