    Three Hard drives?

    This is not a question about Feisty, but about computers generally.

    I'm wondering if it is possible to have three hard drives.

    My current setup has two hard drives, one CD-R/W drive and one DVD-R/W drive. Is it possible to disconnect the CD-R/W drive (which is superfluous) and connect up a third hard drive (on the same cable as the DVD-R/W).

    Of course.
    Your device nodes may move around, depending on how you hook it up, but only /dev/hd*. The /dev/disk/by-* ones won't move.

      Just an opinion --

      Is your DVD an IDE/PATA or an SATA? (probably the former)
      Do you already own the third hard drive?

      If you have the choice, I'd go with a SATA hard drive (of course, connected by SATA cable to the SATA connector of your motherboard).
      If you already own the hard drive and it is IDE, then sure, use it.
      SATA hard drives are just so much easier and more cooperative to deal with, IMHO.

        Re: Three Hard drives?

        Last time I heard, 1 IDE bus connection can manage only 2 IDE drives, a master and a slave. So, to go beyond 2 IDE drives in your computer you will need 2 or more IDE bus interfaces, right? My new Intel motherboard came with only 1 IDE interface -- and 4 SATA bus interface connections. I take it that the trend is away from IDE and toward SATA drives -- prolly explains why the IDE drives are so cheap, and getting cheaper.

          Everyone's right, but if you read the original post carefully...

          Only IDE cables can have multiple devices on one cable, so it is IDE; and yes, there is space; he's removing one CD-RW drive.

            Yes, and some boards had two IDE connectors, Primary and Secondary IDE, and each connector could support two IDE devices (Master/Slave).


            " . . . on the same cable as the DVD-R/W"

            That's the part I overlooked, which is why I asked if the opticals were SATA (and so you were freeing up a SATA for a SATA HD).

            This is one of those cases where the more we say, the more unclear it becomes and cluttered with words galore, but it's clear that YOU know what you are doing!

                Wow. Thanks for all the comments.

                About 2-3 years ago I purchased some new hard drives and installed them in my computer. For a while I had some strange belief that I had a spare 40gb HDD hanging around. The problem was I couldn't find it so I thought it must have been a figment of my imagination.

                Yesterday that figment of my imagination was discovered in a box in my garage - hence the question.

                  Re: Three Hard drives?

                  Well, I now have 3 hard drives and 1 DVD-RW drive.

                  Now I have to get the hdd to work.

                  BIOS recognises it. That's good.

                  Going into System settings shows that it is there.

                  I need to do the following:

                  1. Format it (there is data on it that needs to be wiped)

                  2. Prepare and mount it so I can use it.

                  As per instructions elsewhere (http://kubuntuforums.net/forums/inde...78813#msg78813) I present to you the following:

                            Actually, what I'd really like is the following configuration:

                            sda: Root and Swap (where Feisty is)
                            sdb: Home
                            sdc: Music

                            4 partitions. Is that possible? it would involve juggling files from disk to disk to make it work I assume.

                              Sure 8)

                              1. Reformat the "newbie" disk (assumedly /dev/sdc) by means of GParted.
                              2. Update "fstab" accordingly (further reading) and mount the "newbie".
                              3. Move files as appropriate and relocate /home as described in this text.

                              In doing so, please, ask in case of doubt - guesswork could prove lethal (!).
