It's only for the first time, an indication by the slice code that it didn't find a valid slice [fdisk] table.) What you should probably do before all of the above is zeroing out the old junk from the MBR: dd if=/dev/zero of=/dev/rsd1 count=100 This will ensure the `disklabel -Brw sd1 auto' creates a FreeBSD-only disk. If this still fails, please also post the related parts from the SCSI device probe when booting your duplicate disk. -- cheers, J"org joerg_wunsch@uriah.heep.sax.de -- http://www.sax.de/~joerg/ -- NIC: JW11-RIPE Never trust an operating system you don't have sources for. ;-)
