An EEPROM can be electrically erased. Thus, with an appropriate driver an EEPROMdisk card could support the WRITE and FORMAT calls as well as the READ & STATUS ones. EEPROMs can have a limited number of writes and may not be able to erase single bytes (just blocks) and are much slower to write than to read. None of these would cause problems in this situation. -- David Wilson School of IT & CS, Uni of Wollongong, Australia david@uow.edu.au
