7/29    Reposting of Linux question (didn't catch responses before post was
        deleted) - If I mount a partition listed as "Unknown," but I mount it
        anyways, would the data get corrupted?  That is, fdisk -l shows my
        Win98 FAT32 partition as Unknown, but I type the following command:
        mount -t vfat /dev/hda /mnt/win98
        and I'm able to access it.  Please don't delete replies till Monday
        night.  Thanks.
        \_ It depends.
           \_ What does it depend on?
              \_ That depends.
                \_ Yes.
        \_ Let me guess, you are using System Commander or other bootmgr?
           The answer is: you won't corrupt the data.  System labels
           in the MBR (which fdisk shows) are basically irrelevant;
           you can change a FAT label to Xenix and still mount the
           partition -- mount doesn't read the partition table.  The labels
           are used by OSes to automatically recognize partitions in some
           cases -- e.g. DOS/Windows needs them, RedHat installer looks
           at them, but once the system is setup, all the mount info
           is retrieved from /etc/fstab.  This is all true, of course,
           if the data on your disk isn't corrupt.
                \_ Thanks much; no thanks to the wise-asses above.
                   System Commander is exactly what I'm using.  I wanted
                   to share partitions b/t 98/Linux/2000, and didn't want
                   to corrupt any data when writing from Linux.  Do you
                   know if Linux can also read and write to NTFS without
                   corrupting any data?
                   Which websites / newsgroups are good for Linux
                   configuration discussions?  RedHat's site is a little
                   hit-and-miss.
                   \_ System Commander uses the "Unknown" label to hide
                      partitions that a particular OS shouldn't see.
                      It's because in some cases (e.g. DOS/Windows on
                      a second primary FAT partition) the OS gets
                      confused.  Linux doesn't get confused; turn off
                      the partition hiding option in the Linux boot
                      config (it's in the menu), and you'll see the real
                      MBR under Linux.
                      For sharing partitions, I recommend you use a FAT32
                      setup which can be read/written by all 3 OSes.
                      Linux could access NTFS readonly last time I checked;
                      dunno if they support writing in the latest kernels.
                      As for support sources...  Read FAQs/HOWTOs and
                      ask on comp.os.linux.setup.  After losing
                      the data on the disk 2-3 times because of some
                      mistake, you'll understand how it all works. :)
                      \_ Are there any free newsgroup servers out there?
                         http://Usenet.com charges $139.65/year!
                        \_ http://www.deja.com  Oh, sorry, you wanted porno.
                           \_ deja was too slow and I kept timing out.
                              Who still uses newsgroups to get porno
                              when you have web pages?  Anything faster
                              (and free)?

2/19    I program a lot by sshing to a Linux cluster.  So I'm used to using
        Xemacs to code.  This works fine from a Linux or Windows workstation,
        but sometimes I have to use a Mac.  On Mac, the meta is usually
        bound to option, but that often doesn't work over ssh for some reason.
        This makes using emacs a real pain.  Any suggestions on how to fix it?
