hi,
i like to make a pendrive as a CDROM drive (Read only drive)
is it possible? if yes how to do that ?

thanks in advance

weird ,i read it over and over and now i think i know what you mean . [ if not how the heck could it ever be made into a cdrom drive. lol]
i assume you want to make it write protect ,so that nothing else can be copied to it,some have a little switch on them for that !
