We encountered strange problems with the hard drive while installing Ubuntu. I hope someone here can provide us with some suggestions. We try to install ubuntu on a workstation with one 1T Samsung SSD on the M.2 port and one 12T Seagate hard drive on the SATA port. However, Ubuntu in 18.04, 20.04.4 and 20.04.1 could not detect the 12T Seagate hard drive during installation, while Windows 10 could easily detect it. Even after installing Ubuntu on SSD, we can't see the hard drive through sudo fdisk -l.

Meanwhile, the output of sudo lsblk is demonstrated as follows:

We have tried to switch the SATA port connected with the hard drive, but it still did not work.

I would appreciate it if anyone here could help us solve this problem!

Update:

1. We have tried the latest Ubuntu 22.04. Unfortunately, it also did not work.

2. The screenshot of GParted is here
