Memory Stick
Duo is a memory card type developed by Sony that is compatible with a wide range of electronic devices. Many adapters and memory card readers are available for connecting a Memory Stick Duo to a computer.
Adapter Not Recognized
If a Memory Stick Duo fails to show up as a drive on your computer, it may not be correctly attached, or it may have a malfunction. On some systems, including Windows 7, a drive will be hidden from the Computer view if it is empty. Test the adapter in a different USB port or on a different machine.
Corrupted Data
If data cannot be read or transferred from the adapter, the files on it may have been corrupted or damaged in some way, usually because a read/write operation was unexpectedly interrupted. Third-party software tools are available that will attempt to recover files from damaged cards.
Other Issues
Other adapter problems can result from a software issue, such as files being incorrectly saved, the right drivers not being installed, or the files on the card being saved in a read-only format.
