    Hello,

    We just installed and mounted a 2nd HDD(secondary ide channel) on a Dedicated Server on FreeBSD 4.8 and look what it gives:

    ] df
    Filesystem 1K-blocks Used Avail Capacity Mounted on
    /dev/ad0s1a 2015918 52114 1802532 3% /
    /dev/ad0s1f 22479870 16924774 3756708 82% /usr
    /dev/ad0s1e 4031950 73418 3635976 2% /var
    procfs 4 4 0 100% /proc
    /dev/ad2s1e 76958474 4 70801794 0% /drive2

    ] df -h
    Filesystem Size Used Avail Capacity Mounted on
    /dev/ad0s1a 1.9G 51M 1.7G 3% /
    /dev/ad0s1f 21G 16G 3.6G 82% /usr
    /dev/ad0s1e 3.8G 72M 3.5G 2% /var
    procfs 4.0K 4.0K 0B 100% /proc
    /dev/ad2s1e 73G 4.0K 68G 0% /drive2

    ] cat /etc/fstab
    # See the fstab(5) manual page for important information on automatic mounts
    # of network filesystems before modifying this file.
    #
    # Device Mountpoint FStype Options Dump Pass#
    /dev/ad0s1b none swap sw 0 0
    /dev/ad0s1a / ufs rw 1 1
    /dev/ad0s1f /usr ufs rw 2 2
    /dev/ad0s1e /var ufs rw 2 2
    /dev/acd0c /cdrom cd9660 ro,noauto 0 0
    proc /proc procfs rw 0 0
    /dev/ad2s1e /drive2 ufs rw 2 2

    The problem is that from 73GB (80gb hdd) it only sees free 68GB.

    How can i check if it has bad sectors? A friend suggested me low-level format but I never done that before under unix.

    Also, do i need to be in single-user (I dont have physical access, only remote root via ssh).

    Thank you.
