Hi,
There should be two slots on the device where you can insert PCMCIA flash cards: slot0 and slot1
Depending on which of these you have got the card in, type in:
dir slot0: OR
dir slot1:
Also, you can try the commnad 'show file systems' which will display a list of installed file systems.
Hope that helps.. pls rate helpful posts.
Regards,
Paresh.
