So I was a really good BBQ the other week. (Hi Spencer)
Anyway a friend of mine who gate crashed the party brought his 4GB card to show me as it wasn't working in his new Toshiba M5.
He was looking for me to format it using a formatter for the PPC. We tried it, but no luck...
Upset that he couldn't get the other 3GB's out of his card he trawled the net... He eventually found the answer here...

Trust the Aximsite to know it...
He did most of the solutions on the page to no avail. The one that did work was by MarcusA78 (good work fella)...
"At first, you need a HexEditor. http://www.sweetscape.com/010editor/
Put your card in the cardreader and run the Programm.
Choose "Open Drive" from the Menu and select the Physical Drive of your SD-Card.
Choose "Edit" -> "Select Range" from menu.
Start Address: 0
Size: 512
Press OK
Select "Edit" -> "Fill Bytes" from menu
Start Address: 0
Size: 512
Hex: 0
Decimal: 0
Press OK
Save.
Remove the SD-Card from the CardReader and put it in your Axim.
The Axim should ask you to format the new card. Press the Yes-Button and everything should work fine.
I've done the same mistake and this works great for me.
Remember that you can't use the SD-Card with your CardReader until you do a Firmware Update! Or just buy a new one with SD-Card 2.0 support"
Nice one... Now to look in to getting a MiniSD with 4GB on it!
