My initial inabillity to get more than 4gb on the card seems to be due to a bug in the file manager app. I had no problem using the whole 7.51gb of formatted space, but I copied data there via xterm. The memory applet in control panel reports correct, and mp3´s play from the card.

On a side note, if the n800 formats the card through the file manager app, it only shows 2gb.

It appears the file manager app is to blame. Do 4gb cards act similarly when formatted through file manager?

Maybe Ill install midnight commander or something.

8gb useable, quite sweet...

EDIT* after I cross the 4gb limit, the file manager app functions fine again. I can copy to and from the card. Just need to get over 4gb of data on thecard, then file manager works.
