Moving SE Database and logfile

Hi, I successfully moved my SE 5.x to a new partition by just copying all database files. I discovered one problem: After moving the files the old logfile *must* still exist in the old directory (could be length of 0) given by the systables. When I try "dbaccess - -" and "start database xxx with log in "newpartition...";" there is a database error if the old file is not accessible. Is there any way to avoid this? Is there a command to stop the logging (like "start database xxx with nolog") ? Axel
