    Re: various update,upgrade, CD boot problems

    I'm thinking that your problem may be more fundamental than just not being able to mount those partitions; the mount command claimed that "/media/data_2" does not exist, when clearly that directory exists according to "ls -l /media". How did you invoke that root shell? How about doing it with sudo instead:
    Code:
    sudo mount /dev/sda1 /media/data_2
    If that doesn't work, try:
    Code:
    sudo mkdir /tmp/data_2
    sudo mount /dev/sda1 /tmp/data_2
    Please post the output of all the above commands.

    Re: various update,upgrade, CD boot problems

    In Accessories --> terminal I simply entered "su" and it asked me for my password and then it gave me the new command prompt with root as the user. Here was when I created the directory and issued the mount and got the error:

    root@kids1-linux:/home/dad# mkdir /media/data_2
    root@kids1-linux:/home/dad# mount /dev/sda1 /media/data_2
    mount: mount point /media/data_2 does not exist


    But later when I did the ls -l /media I didn't do it from root. I'll do the new things you asked and post them. Stay tuned. Thanks for all your help. I really need to access those partitions.

    Re: various update,upgrade, CD boot problems

    OK caljohnsmith, here it is. I entered the commands exactly as you specified. It tells me I need to specify filesystem type. These are FAT32 partitions. Not being expert in Linux I didn't want to try it further and take the chance of killing my FAT32 partition. Obviously there is something wrong that it doesn't know about the partition because isn't mount supposed to find out the filesystem type and the other options for itself without me having to specify? Here's the results of the commands:


    dad@kids1-linux:~$ sudo mount /dev/sda1 /media/data_2
    mount: you must specify the filesystem type
    dad@kids1-linux:~$ sudo mkdir /tmp/data_2
    dad@kids1-linux:~$ sudo mount /dev/sda1 /tmp/data_2
    mount: you must specify the filesystem type
    dad@kids1-linux:~$

    Yes, something must be wrong, because "mount" will normally figure out the partition file system on its own and mount it accordingly. I'm beginning to suspect there is something wrong with your Ubuntu rather than your data partitions though; how about booting your Live CD and run the same commands, and post the output so I can see what happens.

    Same results from live CD. Maybe there IS something wrong with the partitions since Ubuntu can't see them either from the installed OS or from the live CD. Let me say though that Windows can see these partitions. Here is the results from the commands from live CD:

    To run a command as administrator (user "root"), use "sudo <command>".
    See "man sudo_root" for details.

    ubuntu@ubuntu:~$ sudo mkdir /tmp/data_2
    ubuntu@ubuntu:~$ sudo mount /dev/sda1 /tmp/data_2

    Re: various update,upgrade, CD boot problems

    When you say that Windows sees the partitions, can you read and write to them just fine from Windows? And you can still boot into Win98SE on sda1 OK?

    How about trying to mount a couple of your logical partitions and see if that gives the same result:
    Code:
    sudo mkdir /mnt/sda5 /mnt/sda6
    sudo mount /dev/sda5 /mnt/sda5
    sudo mount /dev/sda6 /mnt/sda6
    If that doesn't work, try:
    Code:
    sudo mount -t vfat -o force /dev/sda5 /mnt/sda5
    And if that doesn't work, then I would boot into Windows, open a terminal ("cmd") and do:
    Code:
    map
    That should give the drive letters of your data partitions, and for each one, how about running:
    Code:
    chkdsk /r D:
    Replace "D" with the drive letters of the data partitions, and also run chkdsk on each partition as many times as it takes until it reports no errors. Let me know how that goes.

    Re: various update,upgrade, CD boot problems

    I'm running from the live CD -- this time 8.10 release. Here are the results:

    To run a command as administrator (user "root"), use "sudo <command>".
    See "man sudo_root" for details.

    ubuntu@ubuntu:~$ sudo mkdir /mnt/sda5 /mnt/sda6
    ubuntu@ubuntu:~$ sudo mount /dev/sda5 /mnt/sda5
    mount: you must specify the filesystem type
    ubuntu@ubuntu:~$ sudo mount /dev/sda6 /mnt/sda6
    mount: you must specify the filesystem type
    ubuntu@ubuntu:~$ sudo mount -t vfat -o force /dev/sda5 /mnt/sda5
    mount: wrong fs type, bad option, bad superblock on /dev/sda5,
    missing codepage or helper program, or other error
    In some cases useful info is found in syslog - try
    dmesg | tail or so


    I'll boot into windows and try that chkdsk thing.

    Oh, and BTW, I found out my webcam hangs up this 8.10 live CD. It thinks its a different manufacturer and maybe it's trying to connect with it and can't. When I unplugged it I was able to boot Live. The webcam is OK in 8.04

    Re: various update,upgrade, CD boot problems

    It was successful. I did the chkdsk as you said and it fixed several errors on the "C" drive. The others were OK. Then I cam back here to my 8.04 install and sda was still not visible, but I did the mount command as you wrote (but it didn't like the "force" option, so I just did it without it) and woila! It works. Now I need to get them to be visible in Places -- Computer when I boot up. I'll re-read your posts and see if I can get it done for all those partitions on sda. Thanks a bunch! (Oh, and I'll figure out how to do an official Thanks on this forum for ya!

    Any time you mount a device using "/media/device" it will show up under places. Using the "/mnt" directory wont show.

    Good luck.
    And don't thank me, I had nothing to do with your success.

    Glad to hear it finally works after doing the chkdsk on your partitions. Cheers and have fun with your OSes.
