Hard Drive installation issue

[Dhap]

So im quite advanced when it comes to my pc as i solve near enough any issue but this one is a struggle. I have 3 hard drives: 2 1TB and a 2TB. I got the 2TB hard drive about a month ago and recently started having some issues. The first thing i did was format and initialize the hard drive as i should and it worked no problem. I then shipped a lot of files onto it as my first hard drive was almost full. about a week ago my whole rig slowed down to where nothing would work for about 5 minutes until it came back online. I checked for where the problem was coming from, antivirus etc and then the 2TB hard drive wasnt showing up under MY_PC file path. I went into disk management and got the error "the system cannot find the file specified". as it wasnt being used by my pc in any way i unplugged and let it rest. after about 10 mins i plugged back in and only half of the files were there and they were all system backup files. I thought it was fixed then it happened again. Now i can only see my hard drive in disk management after i unplug and wait a while and plug back in which isnt reliable. I have now uninstalled the hard drive from, my pc through DM as i read it could be a fix on another thread and now im not sure if it will show up in DM again. Kinda stuck help would be amazing.

Are you unplugging and re-plugging internal drive, while pc is turned on?
This is highly inadvisable. Can be done only, if hot plug has been enabled on the sata port, where drive is connected. Also safe removal has to be performed before unplugging.

Can you show screenshot from HDtune health for your drive?

Have you tried a different cable and port on the motherboard? Have you tried the HDD in another computer?

I cannot as it wont show up anywhere apart from bios and disk management

Just show the screenshots - from Device Manager (disk section expanded) and
Disk Management.

What does HDtune health section show?
