    Fixing up /etc/fstab

    Having messed up my Debian system I used the hdd-install on Knoppix 3.2 to reinstall. While everything works fine there are a few things I'm still trying to fix up.

    The output of 'fdisk -l' reads

    Disk /dev/hda: 30.0 GB, 30005821440 bytes
    240 heads, 63 sectors/track, 3876 cylinders
    Units = cylinders of 15120 * 512 = 7741440 bytes

    Device Boot Start End Blocks Id System
    /dev/hda1 * 1 258 1950448+ 83 Linux
    /dev/hda2 259 516 1950480 82 Linux swap
    /dev/hda3 517 3876 25401600 83 Linux

    and /etc/fstab reads

    # /etc/fstab: filesystem table.
    #
    # filesystem mountpoint type options dump pass
    /dev/hda3 / ext2 defaults,errors=remount-ro 0 1
    /dev/hda2 none swap sw 0 0
    proc /proc proc defaults 0 0
    /dev/fd0 /floppy vfat defaults,user,noauto,showexec,umask=022 0 0
    /dev/cdrom /cdrom iso9660 defaults,ro,user,noexec,noauto 0 0
    # partitions found by Knoppix
    #/dev/hda1 /mnt/hda1 ext3 noauto,users,exec 0 0
    #/dev/hda3 /mnt/hda3 ext3 noauto,users,exec 0 0
    # Added by KNOPPIX
    /dev/hda1 /mnt/hda1 ext3 noauto,users,exec 0 0

    What I'm trying to change is....
    (1) For /dev/fd0 I'm guessing it's as simple as changing 'vfat' to 'auto' to allow all floppy disks to be read.
    (2) I'm trying to change /dev/hda3 from ext2 to ext3. Booting from the Knoppix CD I ran 'fsck -f /dev/hda3' which found 1.4% non-contiguous (whatever that's supposed to mean), then back on the hard drive I ran 'tune2fs -j -i 365 /dev/hda3', editted the top line of /etc/fstab to read '/dev/hda3 / ext3 defaults 0 0' before rebooting. All I get is the error 'EXT2-fs warning (device ide0(3,3)): ext2_read_super: mounting ext3 filesystem as ext2'. What's going wrong, how do I fix this?!
    (3) /dev/hda1 is 1.9 G of wasted space. I'm not clear what having it flagged as being bootable by fdisk is all about, but it's not mounted at boot time and booting it, it appears to be my old root partition from my messed up Debian distribution. I'd like to blank it and put it to good use, perhaps by mounting root on it, if it's big enough, and changing /dev/hda3 to /home. Does this seem like a good idea, and how would I do it?
    Many thanks for any help...

    My fdisk -l :

    My fstab :

    Code:
    # /etc/fstab: filesystem table.

    /dev/hdg6  /  ext3  defaults,errors=remount-ro  0  1

    /dev/scd0	/cdrom	auto	ro,noauto,user,exec	0 0

    (1) My FDD reads/writes OK ...
    (2) error 'EXT2-fs warning (device ide0(3,3)): ext2_read_super: mounting ext3 filesystem as ext2' - I get the same error, my system runs OK. I don't worry about it, it always does this.
    (3) Don't know ...
