    fstab and duplicate partitions
    I'm having problems with the partitions on my 80 GB Seagate hard drive. I have made 4 partitions. The machine is a beige G3 Mini-tower so by default the first partition is under 8GB. Suddenly (I don't know when this happened) I have dupllicates of each partition except the OS partition. This is making the Jaguar unstable. From the Finder, things seem to be OK, however

    ls
    ls /Volumes
    Backup Backup 1 Sandbox Sandbox 1 Whitestar9 Whitestar9 1
    and

    df
    Filesystem 512-blocks Used Avail Capacity Mounted on
    /dev/disk0s6 15727168 10802640 4767264 69% /
    devfs 186 186 0 100% /dev
    fdesc 2 2 0 100% /dev
    <volfs> 1024 1024 0 100% /.vol
    /dev/disk0s7 15727168 9384784 6342384 59% /Volumes/Whitestar9 1
    /dev/disk0s8 20969696 3796248 17173448 18% /Volumes/Backup 1
    /dev/disk0s9 103862080 80703232 23158848 77% /Volumes/Sandbox 1
    automount -fstab [513] 0 0 0 100% /Network/Servers
    automount -static [513] 0 0 0 100% /automount


    My Files are now in Sandbox 1 instead of Sandbox and in Backup 1 instead of Backup.

    How can I correct this problem?

    Thanks for any help!

    Cool
    Here is what I would do. Bring your system down to single user mode. Then unmount all filesystems. Looking at your fstab you should only have the root partition mounted (/). Now I would save a copy of the fstab file, then I would edit the fstab file and restore everything to the correct mounts. The next thing I would do is rename the old mount points, the one with the 1s in them. Then the next step is to bring you system but up to multiple user mode. Since I am more comfortable with IRIX and AIX, just reboot the system, If all goes will you should have your correct mounts again. If so you can remove the backup copy of the fstab and directories or folders.

    Now for the disclaimer, I have a good working knowkedge of IRIX, Solaris, SunOS, AIX and HP-UX. I am just starting to get a feel for Mac OS X. So if you try this beware. I know it would work with any of the above favorites of Unix.

    Side note, I am assuming that you are comfortable in working with Unix at the command line.

    To get your system to single user mode. Reboot your system or boot your system and press command (Apple key) s. I believe that will getyou into single user.

    Another follow up question: why do I have multiple fstab files?
    ls fstab* tells me this:

    /etc/fstab.hd /etc/fstab.rd /etc/fstab.sd

    You can do a man fstab. Hopefully that will tell what each of those fstab files are used for. I will have to look at mine and see.

    A post on Mac OS Hints complains bitterly that Apple hasn't updated the man file for fstab to include fstab.rd, fstab.sd or fstab.hd.

    Also they aren't there in Panther... Contents of fstab.hd:
    "IGNORE THIS FILE.
    This file does nothing, contains no useful data, and might go away in
    future releases. Do not depend on this file or its contents."
