Does anyone have an idea what is happening? There seems to be a big problem with DAT support. We should put a WARNING someplace, maybe even at boot up in the driver, until it is fixed. This is about the third DAT bug report in a few weeks. I just did a full dump/restore of two big partitions with an Exabyte 8200 on -current, so it isn't a general tape problem. -- Peter Dufault Real Time Machine Control and Simulation HD Associates, Inc.
