    I can't seem to get this right.
    Added new drive /dev/sdc then:
    #/sbin/fdisk /dev/sdc then i created a primary partition, then :
    # /sbin/mkfs.ext3 -m 0 -j /dev/sdc1
    then made a mount point and mounted it
    #mount /dev/sdc1 /hometwo
    works OK, but i get this error when i do; :
    fdisk -l /dev/sdc1

    Disk /dev/sdc1: 73.2 GB, 73270761984 bytes
    255 heads, 63 sectors/track, 8907 cylinders
    Units = cylinders of 16065 * 512 = 8225280 bytes

    Disk /dev/sdc1 doesn't contain a valid partition table
    So whats up here ?

    After the partitioning/repartitioning a reboot is neeed before you can go on making file system in it.

    So as soon as you save the partition and come ot of fdisk , reboot the system to take effect

    Disk /dev/sdb doesn't contain a valid partition table
    
    I'm getting the above when attempting to mount a secondary backup drive that has DATA on it, need to restore the backups from there.

    Anyone know a fix?

    mount -t ext3 /dev/sdb /backup
    mount: wrong fs type, bad option, bad superblock on /dev/sdb,
    or too many mounted file systems

    Go on, have a guess
    Then you'll need to do a lot of searching on google as you have a corrupt file system. They can sometimes be recovered, but it's beyond the scope of these forums. A few hints: Run fsck and see if it's repairable. Try disabling the journal if inode 8 is the problem. Much beyond that you'll need someone who knows how to troubleshoot file system problems as you can easy end up wiping out recoverable data if you don't know what you're doing.
