Hey All,

Is there something special I have to do to get my N900 to use an ext2/3 formatted microSD card? It tells me the card is invalid if it is formatted to either of these but works fine if it is fat32...

Thanks,

Isn't your issue one part the formatting software within the N900 (and its ability to read another ext2/3 partition) and the card controller's software on the memory card?

The former would be something worth putting into Bugzilla, while the latter is at the card level and a lot harder to solve.

If you're just going by the message that pops up when you insert it.. it's because Maemo by default tries to mount it as fat.

That's why most people suggest 2 partitions on an SD card.. a small 100MB first partition thats fat.. just to shut maemo up.. and the rest EXT2/3.

If you insert the ext3 card, open a terminal, and mount it by hand:

for example (note, mmcblk1p1 is a guess, I have no idea what the N900 removable card device is), it should work.

filesystem support is implemented inside OS - card readers have no clue whatsoever about what data is stored on the memory card..

That makes sense - its very, very, stupid but makes perfect sense. Thanks much, I'll have to setup my SD card as such.

@ARJWright I format my SD card using GParted on Ubuntu - and the card reads fine on both my laptops so I was assuming it was an issue with the phone itself.

How do I mount the second partition on my media card? /dev/mmcblk1p1 is the location of the first partition however /dev/mmcblk1p2 is not the location of the second partition... and since the n900 lacks the fdisk command I cannot find my second partition.

Use tab completion or do an ls /dev/mmc*

According to running ls /dev/mmc* my N900 is only seeing the first of the three partitions on my storage card... Ideas on why this is and how i can make it see my second and third partitions that are ext3?

Thanks,
~Jeff

Have a look at /proc/partitions and do a dmesg | grep mmc in the console to see if the partitions show up to the kernel.

Does the N900 have partprobe?
