    External Hard Drive not working


    Hello, I have seagate M3 external hard drive, formatted in windows and with data on it. I was not able to mount it in win, not in linux. But device is recognized. I have replaced disk board with new one and it still not work.

    Here is some info:
    Code:

    Hi and welcome

    The external disc seems to be recognized as device sdb.
    You can find out the partitions on it via
    Code:
    parted -l
    Access can be achieved via
    - create a directory, e.g.
    Code:
    mkdir /mnt/sdb1
    - mount the device, e.g.
    Code:
    mount /dev/sdb1 /mnt/sdb1
    - list the directories/files, e.g.
    Code:
    ls -la /mnt/sdb1/
    Dont forget to unmount before you detach the external drive
    - exit all programs accessing the mountpoint(s)
    Code:
    unmount /mnt/<MOUNTPOINT>

    Hello, and thank you for welcome greetings.

    Code:
    parted -l
    and
    Code:
    fdisk-l
    and gives me only blank line, I don't know why?

    Also
    Code:
    mkdir /mnt/sdb1
    does not work? Maybe because I am switching disk through different USB ports? But I have tried sda1 with no success with ony one disk connected

    I must mention I am running live version of parted magic linux.

    Thank you for any further help. I would really appreciated it. I have not much knowledge in Linux systems, so if we go through steps it would be nice idea Thank you very much!

    I was a bit confused at first, because parted should at least show internal harddiscs.
    Then I realized, that sda is also an external disk, namely a WesternDigital passport.

    Ok, attach your Samsung m3 usb disc,
    wait until it shows up in dmesg
    then try parted -l again

    The point of parted -l is to list the existing partitions on this disk.
    This information can then be used for the mount command.

    Ok lets start all over for better transparency.

    - I have restarted computer, and live distro of parted magic.
    - I have connected only cd-roam and external hard drive

    dmesg | grep -i usb gives me

    Code:
    [   79.147291] usb 4-1.2: >new high-speed USB device number 4 using ehci_hcd
    [   79.233277] usb 4-1.2: >New USB device found, idVendor=04e8, idProduct=61b3

    lsscsi gives me
    Code:
    root PartedMagic:~# lsscsi
    [0:0:0:0]    cd/dvd  Optiarc  DVD RW AD-7261S  1.03  /dev/sr0 
    [6:0:0:0]    disk    Samsung  M3 Portable      3     -
    sudo parted -l gives me nothing

    in File manager I have error for: Mount /dev/sr0
    Code:
    udevil: /dev/sr0 is known to mount - running mount as current user
    udevil: warning 45: options ignored for device in fstab (or specify mount point)
    mount: no medium found on /dev/sr0
    Thank you for your help Irithori

    I don't think this piece of advice will help in this situation, but it's good to keep in mind anyway:

    Some USB drives don't have a partition table; the file system is formatted directly to the device itself, rather than a partition within it. Thus, you would mount /dev/sdb or /dev/sda rather than /dev/sdb1 or /dev/sda1. Also, some might have a logical partition instead of a primary partition. In that case you would mount /dev/sdb5 or /dev/sda5.

    But I'm guessing from the output you've shown that your USB drive isn't even being assigned a device at all. Do you see it at all when you run gparted?

    Hi, thank you. No I don't know whats wrong. I cant see the device in gparted. I think there is something wrong with filesystem or format? Could I somehow copy raw data (data blocks) to another disk?

    Code:
    cannot mount partition [/dev/sda]: filesystem may not be supported by either fsarchiver or the kernel.
    Code:
    /usr/sbin/partimage: /lib/libssl.so.1.0.0: no version information available (required by /usr/sbin/partimage)
    Volume size: 4246732800 bytes (4050 MiB)
    The file system of [/dev/sda] is [-unknown-], and is not supported

    I took a quick look at the spec sheet for this drive, odd they don't like Linux as supported only Windows and later versions of OS/X. Says its a USB drive have you changed what USB port it is plugged into? I ask because of two things first spec sheet says its a USB 3 drive and maybe its moved to a USB 2 port. Second if this is a desktop computer I've seen some USB devices that won't work in the front ports of desktop, but will work if plugged into the back ports.
