Preparing the target disk with MBR or GPT or Dedicated (use GPT except you have a good reason not to), then use dump + restore. You can find more information here: http://www.wonkity.com/~wblock/docs/html/disksetup.html#_the_new_standard_gpt http://www.wonkity.com/~wblock/docs/html/backup.html#_copying_filesystems The advantage of dump | restore is that only blocks in use will be copied, and it works on file system level (instead of disk block level like dd). Initializing the target disk prior to starting the copy operation will make sure the partition data is being written to the correct places. -- Polytropon Magdeburg, Germany Happy FreeBSD user since 4.0 Andra moi ennepe, Mousa, ...
