How to Eject a PCMCIA Memory Card

  1. Make sure the PCMCIA memory card is not being used.

    Remember, a PCMCIA memory card is "being used" if a shell or an application is accessing any of its files or directories.

    If you are not sure whether you have found all users of a PCMCIA memory card (a renegade shell hidden behind a desktop tool might be accessing it), use the fuser command, as described in "How to Find Out If a PCMCIA Memory Card Is Still In Use".

  2. Eject the PCMCIA memory card.

    # eject pcmem0

    You'll have to eject the PCMCIA memory card by hand. If you are running Windows, look for an onscreen message that says you can now eject the PCMCIA memory card.

    If the PCMCIA memory card is still in use, the following message appears:

    /vol/dev/pcmem/noname: Device busy

    In this case, return to Step 1 and make sure no one is using the PCMCIA memory card, then eject it again.
