Luckily, it's not really an important drive (from a data point of view) in this system: $ df | grep ad0 /dev/ad0s1a 99183 50162 41087 55% / /dev/ad0s1e 413695 1 380599 0% /slow I'll get a new drive in there ASAP. I'm glad it's not the SCSI drives which are failing: $ df Filesystem 1K-blocks Used Avail Capacity Mounted on /dev/ad0s1a 99183 50162 41087 55% / /dev/da1s1f 17130052 15553651 205997 99% /home /dev/ad0s1e 413695 1 380599 0% /slow /dev/da0s1e 17130052 10675758 5083890 68% /usr /dev/da1s1e 254063 156203 77535 67% /var procfs 4 4 0 100% /pro -- Dan Langille : http://www.langille.org/
