    Cannot see other HDD

    Hi,
    First I must say I'm *totally* new to Linux and Ubuntu.

    I installed Ubuntu Server 10.04.4 (only: no other OS) on a Pentium 4 machine. I intend to use it as file server, but occasionnally as a PC - so I also installed the graphical interface (Gnome).

    I can see the 2 small HDD which were present at installation.

    However, being an old machine, I added a PCI card (PATA) so to be able to add 2 large HDD eventually. (Card is: Sabrent, 4-port SATA PCI Host Controller with RAID function, but I do not intend to use RAID function for now). Oh and I also replaced the Power supply so I could have power through SATA cables.

    While I see the card appearing in the disk utility, I do not see any HDD that I attach to it. I tried both the external connectors and the internal connectors. Don't see it in the Mount Manager either. And... must now add I do not see it in BIOS either....

    EDIT: One more factor, if this can rings a bell: prior to install Ubuntu, I physically removed the HDD that contained Windows XP. It was (also) an IDE drive as the two being seen. Was probably 'master' ??... Could this explain something here (why I can't see new drives in BIOS) ?

    Both drives I tried are NTFS. I installed NTFS Configuration Tool also. One of the drives I tried is 1 TB, the other was only 160 GB. The disks are 'physically' working (I can sense it).

    What am I missing?

    Thanks,


    System:
    Motherboard: Asus P4B533
    Pentium 4, 1.6 Ghz, 2GB memory
    Graphic card: Matrox Millenium G450 AGP
    OS: Ubuntu Server 10.04.4 with Gnome interface

    UPDATE:
    MORE after hours of struggling with it.

    I have tried the following:

    - disconnected HDD that contains OS. Of course hanged at boot-up but here's the info:

    Detecting Primary Master : none
    Detecting Primary Slave: DVD-RW...
    Detecting Secondary Master: none
    Detecting Secondary slave: WDC ....
    Secondary Slave drive fails

    So no sign here yet from my newly connected drive on the SATA PCI card.

    Then I tried to simply remove jumpers from both IDE drives... And nothing boot.
    Tried to put the one on the drive containing OS only, not the other IDE drive - still impossible to boot.

    So I put both back in place as they were initially. Have no additional idea what to do with it really...

    In BIOS all drives are set to 'Auto'

    Did you check the log files if any error messages occurred?

    What does
    Code:
    sudo fdisk -l
    run in a terminal tell you; it should list all the disks with their partitions and sizes, though you may find the partition sizes difficult to understand, eg
    Code:
    Disk /dev/sda: 163.9 GB, 163928604672 bytes
    255 heads, 63 sectors/track, 19929 cylinders
    Units = cylinders of 16065 * 512 = 8225280 bytes
    Sector size (logical/physical): 512 bytes / 512 bytes
    I/O size (minimum/optimal): 512 bytes / 512 bytes
    Disk identifier: 0xd44cd44c
    
       Device Boot      Start         End      Blocks   Id  System
    /dev/sda1   *           1        1305    10482381   83  Linux
    /dev/sda2            1306       19668   147500797+  83  Linux
    /dev/sda4           19669       19929     2096452    5  Extended
    /dev/sda5           19669       19929     2096451   82  Linux swap / Solaris
    In fact, in the Blocks column, it is approximately 1,000,000 per GB, so my sda1 which is 9.9GB shows 10,482,381 blocks.

    Yes indeed I can only see two drives (plus the CD-R drive) there.

    In that case, and assuming the disk itself still is working, I suspect that you need to play around with the jumpers on it, if there are any and try all combinations until, hopefully, the disk is detected by BIOS and Ubuntu.
