It is used when the 48 is turned OFF. The card runs off of 48 batteries only when it is turned on. Thus, if you are a regular user like most, the card is supported most of the time by its internal battery. > ian peraino@gmuvax.gmu.edu

I even remember hearing this before and forgot about it totally. Well since it is supposed to last some 2 years anyway I have an alarm set for July of 92 to tell me to replace the battery.. I am just not all that concerned as I back up my at least once every two weeks. It saved my ass a while back when a dbase program corrupted the memory and when it finally surfaced, I ended up going back through my backups 1 1/2 month to find a clean copy. So.. I guess the question is; Is there really a problem with these cards? ian -- -=Runaway Daemon=-
