Please note that you will still need available RAM to run the programs. AutoCF is available for download at the web site. While in CFpro, double tap the directory name to open it. The file will be copied into the directory you had previously opened.
Some larger cards require a little extra time and battery power for proper detection and sizing.
If the unit s battery power is low, it may fail altogether. First, change batteries if appropriate. If that is not the problem, insert the card into a desktop CF reader and perform a Scandisk operation. This should allow you to find and fix any errors on the card. You may need to reformat the card, but this will erase all of its data.
