Hello
I am on Ubuntu 18 and when I plug in a USB stick or an external hard drive (both recognized under Windows), they are not detected, all my ports are working perfectly.
Do you have a solution?
Thank you

    The file system of your USB drive may not be compatible with Ubuntu. You need to check the properties of the drive to see if it uses NTFS: if so, you need to format the drive and choose FAT32 as the file system (note that formatting the drive will result in the loss of the files it contains).

      Hello,
      Linux can read/write NTFS partitions perfectly well.

      What do you mean by "they are not detected"?
      - Do they not appear in the output of the lsusb command?
      - Do they not appear in the file manager?

      They may very well be detected but not show up in the file manager if they are not mounted.

        Indeed, I didn't say anything; Linux can read NTFS today. I was very misinformed, sorry.

      Hi
      When I plug in my USB keys or external drive, they don't appear on the screen.
      I can't open them; they are all in NTFS, which worked fine before the 18 update.

      Hello,

      With the latest distributions, 
      dmesg
      uses the 
      -w
      option which allows you to keep the terminal open and see what is happening live as it occurs.

      So, open a terminal, run 
      dmesg -w
      and from there connect the device.

      Okay, I didn't know that, I'm a bit old school.
      In both cases, we need to have the info.
      Thanks.

      You're welcome. But indeed, in any case the result is the same ;-)
      Let's say that with 
      dmesg -w
      , if you add 2 or 3 blank lines (pressing <Enter>), you can better spot where the addition of information starts...

      Exactly. I wanted to specify that in my first message, then I changed my mind ;-\

    I propose this:
    1. Unplug your 2 storage devices
    2. Open a terminal
    3. Type: 
    lsusb

    4. Replug your 2 devices...
    5. In the same terminal type: 
    lsusb


    If possible, send the result in 2 different code sections:
    <code>result lsusb1</code>
    <code>result lsusb2</code>

    !!! REMOVE THE '-' between the <> (angled brackets) !!!

    I don't know how to put the chevrons.
    I have two external hard drives and a USB key plugged in, but I believe the key is incorrectly formatted, plus gparted won't launch on my Ubuntu.
    Thank you for your responses.

    I received for sudo fdisk -l

    Should dmesg be cut off at the end and not in full?
    You can start over; you need to use dmesg after inserting the keys and disks.
    Then copy/paste it into a text file and save it.

    Send the file to https://pjjoint.malekal.com
    and provide the link back.

      • Unplug all USB devices you want to list
      • Open a terminal
      • Run the command 
        dmesg -w
      • Create 2 or 3 empty lines by pressing <Enter> 2 or 3 times
      • Plug in one of the USB devices
      • Copy/paste the lines that appeared in the terminal starting from the empty lines you created earlier


      Below is an example. What we are interested in is highlighted in red (after the empty lines). In yellow is an example of a name for a USB stick:

        It looks like there are read errors

        Read Capacity(16) failed: Result: hostbyte=DID_ERROR driverbyte=DRIVER_OK

        When you use the disk and you’re done, do you eject it properly in Windows?
        Maybe the file system is marked as having an error.
        It generally works fine, no copy errors or anything else?

        It would be good to run a checkdisk from Windows.
        See here: https://www.malekal.com/chkdsk-erreur-reparation-disque/
        You can do the check graphically.

        or from Ubuntu: 
        sudo fsck -V -n /dev/sdb1


        It's up to you to decide what’s simpler.

        ~~

        Also check the external hard drives with CrystalDiskInfo
        or from Ubuntu with GSmartControl

    No worries, I’m doing that. The hard drive comes from my laptop which I replaced with an SSD; I formatted the system to turn it into an external HDD.

      Hello,
      I formatted the system to make it an external HDD
      What format? ntfs, fat32, ext4, other?
      How did you format it?

      If we go by the results of the dmesg command, it is not possible to determine the size of the disk... there is an issue with your disk.

      And if gparted won't start, that's not normal, your ubuntu installation is probably shaky. Try with the live-usb. If it's the same thing, you'll need to check the integrity of the iso image with the md5 checksum.

      Unable to repair the disk with Windows even with CrystalDiskInfo
      It was formatted in NTFS with Windows and then I tried to make it a bootable drive for Windows 10 but I couldn't do it so I reformatted it
      I am currently repairing it with EaseUS Partition Master, I'll keep you updated.

      If the information stops there, it means there's still a problem ;-(
      Your disk is detected, but no information about its partition table and/or, failing that, its structure has been retrieved ;-(

      Well, there you go, your drive is accessible at 
      /media/dprave/Dprave
      and you should see it in the file explorer…

      Good evening
      Gparted still doesn't start on my PC. I just plugged in my hard drive and a USB key and I can't see them
      I'm fed up, everything works fine under Windows.

      Gparted doesn't start, or it starts and you can't see your hard drive and your USB stick? (it's not the same thing)

      No, the software doesn't start, so it's impossible to see the disk or the drives, and why doesn't my Linux detect them right away like Windows?
