    external drive not mounting

    I have a Seagate external storage device which usually mounts with no trouble . I decided to install Ubuntu 24.04 and tried to use it but it could not mount.
    I found the the 24.04 so full of bugs that I reinstalled Ubuntu 22.04
    I think the 24.04 must have done something to the Seagate.
    I now get an error message saying 'unknown' error.

    PS: Title should read 'External storage device not mounting'

    Is external drive gpt partitioned?

    Re: external drive not mounting

    It isn't clear what you are doing but I'm guessing you installed 24.04 on a different drive and attempted to mount some filesystem on a partition on the external drive you refer to, is that correct? It would be useful to indicate what filesystem type is on the partition(s) on the external drive you failed to mount. Did you attempt to mount from a terminal and if so, what command specifically did you use? Posting the output of the commands suggested in post 2 would be a first step in getting help.

    Re: external drive not mounting

    Thanks Yancek - All I did was to download the iso of 24.04 from the official site and make a bootable usb using the disk creator. I then changed the boot order to load the usb and the program installed with no problems.
    It worked ok until I decided to try and mount the seagate storage - it would not mount. I then read a few reviews some said they had the same problem. At that point I decided to reinstall version 22.04 from a usb that I have used before. It was then I found that I could not mount the seagate.

    Re: external drive not mounting

    I am now finding on my laptop that Firefox is not loading after using it a few times so I have to restart the laptop. It also occasionally flickers -never done that before ! Have I picked up a bug/virus ?

    Please use Code Tags when posting terminal output. And loops devices are snap apps, so not real devices.

    You show install on NVMe drive, but then no sda or external drive?
    Was it plugged in when you ran commands?

    Should have had you run this as it excludes snaps/loop, which I removed when I added code tags to your post.

    Re: external drive not mounting

    Appears to be NTFS formatted. I suggest you plug the device into a Windows system (NTFS is proprietary and only Microsoft truly knows how it works) and run a full chkdsk to make sure it is complete and consistent. You can then use the safe remove feature in the OS to flush the disk cache (wait for Windows to tell you to ununplug it) then unplug. You can then reconnect it to the Ubuntu system and test

    Re: external drive not mounting

    With a problem such as you were having, posting the filesystem type is basic information you should post initially. You were asked this in post 3! Since your other drive has only EFI and Linux partitions, why do you have a drive with a partition with a windows filesystem? Are you sharing this drive with other computers using windows? If that is the case, it may be a hibernation problem but could be any number of problems with the ntfs filesystem. If you are going to continue to use a windows filesystem on a drive, you need to be aware of this.

    As pointed out above, you will need to use windows to run chkdsk or other software to fix the problems on the proprietary filesystem.
