Thanks pichlo. I've everything backed up, so the only thing is getting the thing to work =P

I've tried to format the card from the Maemo file manager, but then (even if I can mount it after that) none of my PC's reads it (Windows or Linux)

My idea is to have the card partitioned in such way that there is a mmcblk1p1 which should be a FAT partition (in this case around 13Gb) and two Linux Swap partitions after that (mmcblk1p2 and p3)

I find it to be trickier than what I thought =/
