Oh, i see, it changes 1/0 bit to turn on/off write cache. changing it to 0, turns off write cache I suspect. But, Mike said there are issues with the firmware, why not just update it if latest one doesn't have the problem? won't that be better? -Simon On Tue, 08 Aug 2000 01:40:12 -0400, Simon wrote: >Alrighty, now, i'm totally confused.
