I have a Seagate 2.0 TB HDD. I had Ubuntu installed on it and grub on my SSD. I removed the cable when trying to change it. After that when I plugged it in grub showed the black error screen with grub>
. I had a dual boot on the SSD with Windows and I removed it by fresh-installing Ubuntu.
My HDD showed an error when I opened it in disk management on Windows originally and asked about creating GPT or MBR but both commands failed. Additionally it showed on 3.9 GB as the maximum available/formatable size.
Now I am on Ubuntu. My drive shows up in disk menu as 4.1 GB, not 1.84 TB, as does another of my correctly working 2 TB one, but not in fdisk. I tried secure erase but it gives an error.
Error when secure erasing:
