I have a question/problem and searching doesn't seem to provide any simple solution. I flashed my N800 from OS2007 to the latest OS2008 (51-3 version). Using the nupgrade.sh scripts everything seemed to work OK- until I finished. Everytime I reboot, I get a popup message stating memory card is corrupt. File manager complains the card is not formatted and offers to format it- when I do so it complains that it's unable to and that I should use File Manager to format the card. In OS2007 and the first OS2008, I was able to edit the /usr/sbin/osso-mmc-umount.sh file and "turn on" the DOS partition, but the script is different in the latest version.

Did I miss a step somewhere or is my card truly corrupted? Windows can't find anything wrong with the card.
