    hard drive not being found

    I added a 3rd drive to my system to use for storage. but ubuntu doesn't see the drive as being attached. The drive shows up in bios and in windows. I even formatted it in windows to see if that may help with no luck.

    sudo lshw -C disk

    this is what ubuntu sees.

    Partition table entries are not in disk order
    I'm at a loss any help would be appreciated.
    Oh and I installed kubuntu to another partition as well to see if a new install would find the drive.

    Re: hard drive not being found

    Tried booting to live cd with same results. So I disconnected the sda and sdb drives and made sdc to sda and booted to live cd and then ubuntu saw it but putting everything back to normal it's gone again. Anybody??

    Re: hard drive not being found

    Well alot more testing and no further. I put other drives in that spot and some worked and some didn't. Using a live cd. I even put this drive in that spot and it wouldn't show up. Put a dieing drive in there and it had no problem finding it lol. I'm thoroughly confused at this point. oh and windows can see everything I put in there which is the part that really has me scratching my head. Well this has been my evening and I guess no one else has the answer so I guess I just give up for now and hope that something comes to me.

    Re: hard drive not being found

    you're problem might not be that its not being found, rather its not auto-mounting.

    If it's not being seen at all in Ubuntu, I'd be suspect of cable/port. Windows is a lot more forgiving when it comes to flaky hardware (most people don't see that as a good thing).

    Re: hard drive not being found

    Hi.

    Are you still using IDE Drives? If so are the Jumper settings on the drives correct (i.e. master/slave/cable select)?

    Please tell me how the hardware is arranged meaning:
    Who is master/slave on IDE Channel 1 and 2?
    If you are using Cableselect try using master/slave.

    Sidenote:
    If it is not in fdisk -l or lshw Linux doesnt know its there.

    greetings
    /moddie

    ps:
    Just saw it, Grenage is following the same trail of thought I did.

    Re: hard drive not being found

    Yes it's ide and I have changed the pins to master and slave and back to cable select. I have even changed the the cables went through about 12 different cables with no luck. I was thinking the drive or cable were bad.
    but as I said I tried other drives and some can be found and some can't. I just removed a drive from there that has been there for over a 3 years. started getting smart warnings so was trying to add anew drive but it seems that only the western digital drives I have are being seen, but seagate and maxtor drives on that port are not.
    It is in the slave position on the second ide port with a cdr as master.
    thought it might be the ide port as well but I'm not real sure how they work and would think that the master on that port would fail as well. but I can remove the cdr and put the drive as master then it shows up.
    maybe it's just a problem with certain drives and that port IDK.

    Re: hard drive not being found

    Based on your troubleshooting, I would guess that it is indeed the port. It's also possible/likely that the original drive is fine, and that smart was picking up on the port problem.

    Re: hard drive not being found

    I would agree but would that not also mean that the device what ever it be that was on the end portion of the cable would have the same fate? it is ide port 2 with 2 devices on it one device works fine but the one doesn't doesn't seem right but maybe I am no expert when it comes to IDE ports and their internal workings but that is what I am searching for now. lol not that it will change weather the port is dead or not I just want to know now.
