I have an 8gb class 4 SDHC card, and recently it starts saying "memory card is corrupted or unformatted". However i can still view the card on a pc through a card reader.

Through a fair bit of testing with different cards, whats happening seems a bit wierd.

It seems i cannot have two sd cards active in the n800, one card will work on its own in either slot. The second card put in the n800 will not work and it doesn't matter which card it is.

Hope this is clear, any help and advice would be great!
