Cannot mount or detect internal HDD in SMART test, warning sound

[mahesh]

I bought an oryx pro with Nvidia 1070 in Jan 2018. Since yesterday, I could not mount my built in HDD, /dev/sdb does not show up in "sudo fdisk -l" command, but HDD still gets recognized by disks application.

From today, I have issues booting up, I can boot up from secure boot. But disks does not recognize my HDD any more, also I can hear warning sounds every second. The warning sound eventually goes away after 10 minutes. This happens every time.

Is it my HDD hardware issue? Can I still salvage it? Or can I just remove my hard disk? Will it affect anything else?
