Internall HDD not showing in HDD list-when restart says uninitialized

Hi there

I really have a big problem, I have an internal storage HDD 3TB which was fine until a couple of days before

At some point when I restarted my imac it disappeared and the disk utility announced me that a hardrive is uninitialized

I tried everything to remount the drive back but no success:

erase

first aid

reinstall OS

different recovery software

etc.

The disk utility list shows an internal drive ST3000DM001 Media 4.14 GB

and in the terminal there is a disk0 showing as a 4.1Gb

(I listed below the content )

I tried to erase / format this ST3000DM001 Media but I get the error:

"unable to write to the last block of the device

operation failed"

I am really at a loss, is there any chance to recover this HDD? I can't take it easily out, as the iMac has the LCD glued to the body :(

see below the available info

Thank you in advance for help!
