I have the model lower than yours (Satellite 1900), but it has a 30 gig drive... When I called to get drivers for it (my warranty is expired), they helped me out without charging me... Anyways, I've done some digging around on the Toshiba Support website and this is what I found based on your model number (yours is actually on the list, unlike mine): http://www.csd.toshiba.com/cgi-bin/tais/su...Model&x=18&y=14 I see some BIOS updates on there. You might want to take a look. http://www.csd.toshiba.com/cgi-bin/tais/su...gngdglj.0&ct=DL <-- Latest one http://www.csd.toshiba.com/cgi-bin/tais/su...modItemList.jsp <-- List of BIOS Updates
