I guess that writing a valid slice is my problem, have you got any tips on how to create a valid table? Here's what i've tried (all taken from http://www.freebsd.org/handbook/disks-adding.html): # dd if=/dev/zero of=/dev/ad3 bs=1k count=1 1+0 records in 1+0 records out 1024 bytes transferred in 0.001281 secs (799436 bytes/sec) jmo# fdisk -BI ad3 ******* Working on device /dev/ad3 ******* fdisk: invalid fdisk partition table found # and # dd if=/dev/zero of=/dev/ad3 bs=1k count=1 1+0 records in 1+0 records out 1024 bytes transferred in 0.001331 secs (769363 bytes/sec) # disklabel -Brw ad3 auto # disklabel -e ad3 disklabel: ioctl DIOCGDINFO: Invalid argument # and # dd if=/dev/zero of=/dev/ad3 count=2 2+0 records in 2+0 records out 1024 bytes transferred in 0.001283 secs (798099 bytes/sec) # disklabel /dev/rad3 | disklabel -BrR ad3 /dev/stdin # newfs /dev/rad3e newfs: /dev/rad3e: Invalid argument # > > 2) YOU MUST REBOOT.
