Ensure you have automatic write reallocation enabled in the disk's error recovery page (page 1; check it with "scsi -f /dev/rsd?.ctl -m 1" and do "man 8 scsi" to see how to permanently change it). You usually want auto read reallocation enabled also. Then dd from /dev/zero to the partition. -- Peter Dufault Real Time Machine Control and Simulation HD Associates, Inc.
