Mine says corupted as well!I`ve had the card in my 5800 and it was fine for a year, so I`m positive my card is not corrupted. I`ve tried making an ext2 partition in Paragon Partition Manager on a windows xp machine (yes! it does work!).What kind of partition does the N900 require??There are a bunch of option in paragon 0x82 0x83 0x84 and so on ( linux hidden, extended, blabla).Do I assign a letter to the partition as well?
