Be aware that xdd reports 1 MB as 1000000, not 1048576. Though, it looks like dd is the same, so that's probably not helpful. Also, make sure you're passing {i,o}flag=direct to dd if you're using -dio in xdd to be sure you are comparing apples to apples. -- Dave Dillow National Center for Computational Science Oak Ridge National Laboratory (865) 241-6602 office
