Formatting SD cards
From Pandora Wiki
The Pandora OS can read cards formatted with various filesystems, including ext2, ext3, fat32, and if the Community Codec Pack is installed, NTFS. If you have access to a desktop computer, it's a good idea to use the Panasonic SD Formatter, which can improve performance of SD cards.
ext3
To format a card ext3, insert the card into the Pandora, then open terminal, and type: [1]
sudo fdisk /dev/mmcblk0 (use mmcblk1 for the second slot)
't' then '83' to change the partition type to linux, then 'w' to save.
sudo mkfs.ext3 -m 0 /dev/mmcblk0p1 (or mmcblk1p1 for the second slot)
If you want to set a volume name then type:
sudo mkfs.ext3 -m 0 -L volumename /dev/mmcblk0p1
FAT32
The software to format FAT32 is not included with the Pandora, but can be easily installed. Open terminal, and type: [2][3]
sudo opkg update
sudo opkg install dosfstools
Once installed, you can format a card like so:
sudo mkfs.vfat /dev/mmcblk0p1 (or mmcblk1p1 for the second slot)
