Thanks, Lord Possum. I don't have the card yet, hence no volume number
supplied.

I haven't studied the file structure of SD cards yet, so am totally
ignorant of their structure and nomenclature. I'll try the program you
recommend with a spare SD card and see how it goes. Should receive my
OCN6 card in a week and will make a backup using a media reader and
the desktop before inserting it into the PDA. Hopefully, the autostart
inf won't screw things up doing that. I know the program installs
itself upon the card being inserted into the PDA. Probably generates
an encrypted key at that point, too.

Thanks again for your helpfulness.

Cheers,
Larry
