    I've been having a bit of an issue with my 120gb Maxtor hard drive under
    FreeBSD. As of right now, the disk is set up with one NTFS partition,
    but I'm not sure if thats relevant. BIOS reports the correct geometry
    and size, and Windows also reports the correct size. The disk is ad1.

    If do a dmesg, I get these messages relating to the drive:

    ad1: 2014MB <Maxtor 4G120J6> [4092/16/63] at ata0-slave UDMA100
    ad1s3: slice extends beyond end of disk: truncating from 240091425 to
    4108671 sectors
    ad1s5: slice extends beyond end of disk: truncating from 167782797 to
    4108608 sectors

    Steps I've already tried (in no particular order):
    1. A friend said that I could disable the drive in BIOS, and FreeBSD
    would query the controller, and get the info from there. I did disable
    it, but I got the same results.
    2. Checked in Windows XP is the disk is set to a "dynamic disk." I
    understand they are not compatible with any operating system besides
    XP. The disk is listed as "Basic"
    3. I've tried taking the geometry from BIOS and manually putting it in
    from fdisk in sysinstall. With the values copied verbatim, fdisk says
    that they are incorrect, and will not use them. I have also used the
    geometry published by Maxtor. Those numbers work, but the hard drive is
    only around 8gb.
    4. I was advised on IRC to try switching the drive from its position at
    primary slave, to somewhere else. I changed it to secondary slave, and
    had the same results.

    The Values that BIOS gives:
    58853 cyls
    16 heads
    255 sectors

    Values from Maxtor
    (http://maxtor.custhelp.com/cgi-bin/maxtor.cfg/php/enduser/olh_adp.php?p_faqid=596)
    16383 max cyls (238216 actual)
    16 heads
    63 sectors

    The Values that BSD reports (from fdisk):
    256 cyls
    255 heads
    63 sectors

    Thanks a lot.
