Not enough info to answer..
Mac model? Mac OS version? Kind of external memory (flash stick; hard drive?)
Although the label is not clear about it, this forum is for Macs made before 1998 so gets very little traffic. If you are in the worng forum we can get your post moved but can't do that without the extra information.iMac 27-in; Mid 2010 2.93G i7 Quad, Mac OS X (10.6.8), 4GB RAM; ATI5750 1G VRAM

Additional question, how is the external memory formatted?
Mac are not able to write to all file system. Some require third party software for OS X to write to them.
