    Unhappy External USB does not show up in fdisk -l


    Hi there!
    I know there are entries in FAQ and sticky topics about USB-drives, but I can't really make a use of any of them...
    I bought a new 1.5TB internal HDD and put it into an external HDD box connected to my PC via USB. The Problem is:

    I plug it in, dmesg tells me:
    Code:

    When I try mount /dev/sdb the disk clicks (so sdb really is the correct device) and fails to mount, ofc, because it is not partitioned yet (Can't read superblock.)

    The Problem is, I can't partition it with fdisk:
    Code:
    $ sudo fdisk /dev/sdb
    Unable to read /dev/sdb
    And the only hard-disk appearing when I do fdisk -l is my internal hdd sda.

    Please help me with this, I don't want to have spent my money on a HDD so that I cannot use it afterwards .
    Any help would be greatly appreceated!

    Best guess is that there is either a problem with USB enclosure, or with the drive, or with the configuration of the drive. If it is an IDE drive you will want to check the slave/master jumper settings with the enclosure documentation to be sure it is properly configured.

    Thanks for you response.
    In the documentation of the enclosure doesn't say a word about having to set specific jumpers and the hdd (western digital caviar green 1.5TB) was sent without any documentation whatsoever, only a sticker on the disk itself that says, "To achieve full performance: For windows XP, single partition - set jumpers 7-8, all other OS configurations - drive is ready for use as is."

    The disk has 4 jumper-pairs. What would you suggest? Sorry, but I am not really that experienced with hardware and that jumper-stuff :/

    So, show us how the jumpers are configured. Example, using a colon ( : ) for unjumpered pairs, and letter ell ( l ) for jumpered ones: l::: or ::l: where the first example is jumpering the first pair, and the second example is jumpering the third pair.

    Go to the Western digital website and find your hard drive in the tech support section. They will give you all the jumper settings there (Usually downloadable as a pdf file).
    Also look at the enclosure doc to find the settings you may have missed.
    I have found that most hdd manufacturers support even their oldest hard drives.

    Hi, thanks again,

    the jumpers as they are now simply looks like this (none set), which is, according to Western Digital, the "Standard configuration":
    Code:
    ::::
    This would enable SSC
    Code:
    :::|
    This would enable OPT1:
    Code:
    :|::
    And finally this is what one should do just for Windows XP, single partition use:
    Code:
    |:::
    I really don't have a clue wether there is any of the above I have to apply... and I don't know what the following configuration would do:
    Code:
    ::|:
    The enclosure is made by Vosstronics, not Western Digital, but Western Digital appears to use enclosures with the same chipset in their own external hard-disks, and I literally read the manual word by word and it says nothing about jumpers whatsoever.

    So, which jumpers should I try to set?

    Possibly either the drive or enclosure is faulty. At this point I don't know what to say, other than to try the XP mode setting and see what happens.

    BTW, when you turn the enclosure on, can you hear the hard drive spin up? They can be pretty quiet, so you might need to hold it next to your ear to tell. Also, if the enclosure has a fan it makes it harder to tell, but not impossible.

    I would have suggested that, but since the drive is IDE and I don't know if his computer uses IDE or sata drives internally I decided to explore other options first.
