I have a Dell Axim x51v unit.

I was using a 1GB SD Card for the longest time and occasional when I
tried to access the card the system couldn't find it, but it didn't
happen all that often.

I upgraded to a 4GB Transcend model and the Axim has trouble picking
it up most of the time. It does work, but often the system just
can't find it.

I don't know if the problem is physical or electronic.

Can anyone help?
