    Help me find a disappearing hard drive

    I have a hard drive that I barely use on my Ubuntu box. It was recognized and mounted just fine on boot up when I first got it. I was going to back-up some data this morning and I discovered that it was no longer available in my Places menu. It is detected in BIOS. Can anyone help me re-detect it or re-mount it?

    Thanks

    first post results of
    Code:
    sudo fdisk -l
    and then let's see your fstab
    Code:
    gksudo gedit /etc/fstab

    and then let's see your fstab
    you don't need to open it as root to view it,
    Code:
    cat /etc/fstab
    will show it as easily.

    It would probably help to post the UUIDs as well

    Code:
    sudo blkid

    Sorry, what, "cat nano" ?! I think you forgot to erase "nano" here.

    Re: Help me find a disappearing hard drive

    All of the harddrive you have in 2 partitions - both are being mounted - one is the root drive and the other is swap.

    It would appear from the information available that all drives/partitions are available to you.

    Do you have 2 hard drives in your pc - if so then the second appears not to be working.

    Reboot, when you get the opportunity do escape or del or whatever you need to get into bios - make sure that all harddrives are being recognised. If you believe you have more than 1 harddrive then you are going to need to make sure that 2nd is actually physically working. Check the cable s for your drives.

    Re: Help me find a disappearing hard drive

    The second harddrive is seen in BIOS, but still not seen in Ubuntu.

    What is the next step from here? Could it still be something physical (like cables, etc.) if it is seen in the BIOS?

    Thanks all for the help.

    Re: Help me find a disappearing hard drive

    I would yes, if I had a drive recognised in BIOS but not appearing in ubuntu at all then I would make sure that all the cables are seated properly. Remove and check the cables and plug back together, same for the power connectors.
