I think there are issues with /stand/sysinstall playing with disks if you don't boot into it (or there used to be?). Is this disk only going to have FreeBSD on it? If so nuke the MSDOS partition table, # dd if=/dev/zero of=/dev/rad1 count=32 Then label it, # disklabel -w -r ad0 auto Now, add partitions, # disklabel -e -r ad0 Then put filesystem(s) on the partition(s). If you want, for some reason, to keep a MSDOS partition table on the drive, you can play with fdisk(1) to get the disk setup. That is even more fun. > Oh, by the way I can work well on other PC by using one Western Digital Caviar 2850 HD & one Seagat HD. Does this mean two Western Digital Caviar 2850 cannot work well together? Shouldn't make a difference. If you got good dmesg output on the device, you are probably in good shape. -- Crist J.
