Ok.
So, a "Pandora SD card" is nothing more than a normal SD card with 5 directories:
Code:
pandora\appdata\
pandora\apps\
pandora\desktop\
pandora\menu\
with a README.txt that says:
Place all PNDs that should appear in the menu into the menu-subfolder.
Place all PNDs that should appear on the desktop in the desktop-subfolder.
Place all PNDs that should appear both on the desktop AND in the menu into the apps-subfolder.
PNDs will save their configuration into the appdata-subfolder.
Some cards are formatted
exFat, and can not be read by the openPandora without the "codec pack". Most cards are formatted NTFS, however, due to this being a Linux machine, some applications get confused with that filesystem, but most just work (and you can always put the SD card back into a windows machine and manage your files).
So... you can format the SD card on Windows using NTFS as the format, then create those directories mentioned and you have a working card, where you can download PND's to...
Once you put the SD card into the Pandora it will autodetect PND's and fill the menu with them....
personally I always use the desktop to put some preferred applications... for example, the emulator/game I am using/playing... but I have much more apps than I can display on screen... so most are in the menus
Things that can go wrong:
So, in order to break the chicken-egg problem, use a new card (those are already formatted)... and create your directories manually (using thunar or the "explorer")... and download a PND and put it in one of those directories.
You can use your current card to download and put gparted on it to format a new card.
If you do not mind breaking compatibility with Windows, you can use Unix formats like ext2 (ext3 has journalling and will lower the lifespan of your card, however, it is harder to corrupt the card...). For now, stick to NTFS or FAT32.
TIPS
The "Panasonic SD format utility" (for Windows) has been reported to work well, as it did with me also. Mind you, I chose quick format only, not a full format, and selected FAT32.
Panasonic has it here on their site.
