Oh, and just to add a few things that I left out, I am using a N800, with 0s2008 version 4.2008.36-5, and I have just one memory card in right now, a transcend 4gb card. I have tried using it in both the internal card slot and the external card slot, and I have also tried a kingston 2gb card and a sandisk 1gb card all with no success. I have fomatted all the cards using the N800's format utility and I have formatted each card with the Low level format utility on my pc. I have the install tools file installed on my n800 flash. I first put it in the documents folder, and then also tried creating a temp folder on the flash and put the install tools file there. What else am I missing ??
