Ubuntu does not recognise correctly installed second IDE hard disc drive

Hi Malcom,
Could you please post the output of "sudo fdisk -l"? That will tell me more about how you have formatted things and what disks the OS is seeing. Thanks Dave

Dear Dave,

Many thanks for the email.

The new build is not connected up to the net yet but have typed in sudo fdisk (it won"t wear -1 suffix) as you advised and I am typing what came up on screen using a different computer................................ The advice was

fdisk (-1) (-b552) (-u) device
G:- fdisk/dev/HDA (for the first IDE device)
or fdisk/dev/sdc (for the third SCS1 disk)
or fdisk/dev/eda (for the first PS/2 ESD1 drive)
or fdisk/dev/rd/c0d0 of fdisk/dev/cda/c0d0 (for RAID devices).

Is this of any help solving my problem? I am very grateful for your advice.

Cheers,

how about `dmesg | tail`

Dear Dave,

I am very much on the Ubuntu learning curve and the information I sent you last night I suspect does not reflect sudo fdisk-1 and merely from the f disk command in the command line prompt. I did load the Ubuntu OS onto the slave disk independently of the Master. At boot up I am now asked to select which of the 2 identical Ubuntus OS"s to boot from. The master is identified as dev/hdc and the slave as dev/hdd.Each boot leads to the respective drive, but when in the slave drive I cannot access the contents of the master HDD and vice versa. However on checking the disk capacity Ubuntu now recognises 1000Gb of disc space (that is my 2x 500Gb IDE HDDs). I will try though and get the output from sudo fdisk-1

Malcom,
It's actually "sudo fdisk -l" instead of sudo fdisk -1. Give that a try. Dave

Thanks Dave,

Will give it a go probably tonight, and will let you know if not tomorrow (Thursday), on Friday.

Cheers.
Malcolm

Hi Dave,

Thanks for your email I have already identified the master drive as hdc and the slave as hdd on my computer, so the following information on sudo fdisk -l indicatyes to me that the system recognises the 2 hdds. Unfortunately the linux I have just constructed is not connected to a printer or to the net, as yet. I have written the result from sudo fdisk -l and typed it to another computer connected to the net. It seems I may have omitted the information contained within blocks for the hdc device, I am not sure this is imperative, if it is I will re- obtain the info. To reiterate I have the Ubuntu OS installed per disk but neither HDD appears to be able to access the other without rebooting and selecting which disk, which is unfortunate. I will send this off now and await your advices with thanks.

Malcolm,
          The output from the 'fdisk -l' indicates that Ubuntu is seeing both drives. It is possible that the issue is that you haven't told ubuntu to utilize the second drive. It does appear to be formated for linux, so it might just be that it is not mounted anywhere.

          Could you provide us with the output of the 'mount' command, please?

          Regards,
                    --Matt

Dear Matt,

You are spot on with the comment re the 2 drives and I have now resolved the problem as of this morning. I constructed the system only a few weeks ago and there was a BIOS configuration error on my part which had a SATA drive enabled on the motherboard, instead of the 2nd IDE. I have a motherboard which has RAID and eRAID options via SATA drives but I elected to install IDEs instead of SATAs and the RAID option. Once the SATA command was disabled Linux now recognises both IDE drives on either booted HDD. To enter the alternative HDD Ubuntu asks for the password command, but I am not able to boot up the 2nd system once in there, but that may be an issue I can resolve once I learn a little more about what is to do .I am very much on the Linux (and OS construction) learning curve, and am very grateful for the support that the community support line has given me. Many thanks.

Malcolm,
         From your reply, I believe you consider the issue "closed" now. If so, could you mark the question as answered? If not, could you provide a bit more detail about booting from your alternate HDD? I'm unclear as to where the password prompt is coming from... is it from the bootloader, or are you getting messages saying that something failed, followed by a prompt for the root password?

     Regards,
            --Matt

Dear Matt,

Many thanks for the email. I"ll keep the query open pending the following. When I go into "computer" the other disk now appears as an entity where it did not before, irrespective of which HDD I boot from (identical Ubuntu OS per HDD) .

The capacity of each HDD is described as 460GB or so although both are identical Western Digitals IDE HDDs of 500GB capacity each. There is less than 2GBs files installed per drive and I am not sure how much space the Ubuntu OS takes up per drive? When clicking on that disk icon the menu then asks for a password as a security measure but is bypassed when clicked on toproceed without entering the password, and reveals the files in the drive. I don"t see any error messages and am not sure if there is a continuing problem. Thanks.

Thanks Matt Mossholder, that solved my question.
