I recently bought an iMAC desktop computer after years of using a windows based computer. I have 2 Verbatim USB keys containing photos which were loaded on my old computer. One key, which is not passcode protected opens immediately when inserted into a port on the back of the computer but the other which is passcode protected does not. Instead, a V-Safe 100.exe icon appears in the public zone window. When I open this I get a script page which says this program cannot be run in DOS mode followed by many lines of indecipherable script. Any help overcoming this problem would be greatly appreciated.
