it will auto downgrade, so u dun have to be worry.
1st step = back up all ur save files.
2nd step = deactivate all the PSN accounts (otherwise u lost 1 slot of the ID).
3rd step = DL the latest firm ware into thumbdrive (the naming & link are mentioned in the 1st page).
4th step = change / upg ur hdd. (make sure you back up, once u plugged out ur 40gb hdd & even though u plug it back....it will auto reformat where u will lost all ur saves files)
5th step = switch on ur ps3 and plug in the thumbdrive that contain the latest firmware ver.
6th step = restore ur save files.
auto downgrade? means as long as i pluck out my hard disk, my ps3 will downgrade to factory firmware?
anyway, thanks for the info, i find out i can use external hard disk as storage as well. but this might come in handy, planning to get 500gb or bigger but worry bigger wont work..
i got one last question, if i use a new hard disk, do i have to reformat it to Fat32?
