Unable to detect Seagate 2 TB HDD on Dell Vostro 3480

After constantly facing issues with Windows 10 updates, I decided to switch over to Ubuntu 18.04 LTS as I am somewhat familiar with Ubuntu. However, after successful installation of Ubuntu 18.04 LTS, I am facing an issue regarding the detection of Seagate external HDD in Ubuntu.

After searching every forum and having tried everything they proposed (in particular this thread: Seagate 2T external hard drive can not be mounted, detected by lsusb but not by fdisk -l), I am still unable to get my HDD detected.

My terminal output of the commands given in the above mentioned thread are as below:

If drive was NTFS, did you leave Windows fast start up on? That sets hibernation flag and prevents other installs from mounting it normally as read/write. Cannot write into hibernated system without causing potential damage. https://askubuntu.com/questions/843153/unable-to-mount-windows-10-partition-it-is-in-an-unsafe-state & https://askubuntu.com/questions/145902/unable-to-mount-windows-ntfs-filesystem-due-to-hibernation If you do not have Windows, do not use NTFS as it will need chkdsk or defrag which you can only run from Windows. You may be able to manually mount read only.

Thank you guys for helping. I found how it is done.

I visited this answer to Ubuntu 18.04 does not mount 2TB exFat drive even after installing exfat-fuse exfat-utils and found that for Ubuntu 18.04 following commands are useful:

sudo apt-get install exfat-fuse exfat-utils
sudo apt-get install exfat-fuse exfat-utils --fix-missing

Now my HDD is showing in the list as Windows.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
