Please help to restore my External Hard disk

[tiredoftech]

Hello. I have a MyBook 3TB external HDD. Recently, it started giving me problems and today resulted in the drive not becoming accessible.
This is how the drive shows up on My Computer. Previously it would show up as 'My Book' with the used space. G: is the drive.

But if i try to remove the drive, the PC shows the correct name, but it does not get ejected if i try to remove it from there.

Now, i decided to run CHKDSK utility and it gave the following result. I don't know why the insufficient error occurs as the drive is only 1.52 TB full. There is still over 1.4TB of free space left out. Requesting you people to please help me out here. This drive has all my data in it, so formatting is not an option. I don't have any other drive right now to back this up (if it was possible). So only option is to somehow restore the drive to working condition while i buy a new HDD and send this for RMA (few months are left under warranty). Please help.

Run "HDTune" and "CrystalDiskInfo" on this drive and check the status; especially re-allocated sectors count raw value - this must be zero.

To recover data you may use "RECUVA".

i am sorry, but i am technically not very sound. Can you please explain a bit. What exactly do i have to do and check after installing HD Tune pro. And how do i make the HDD run as previously with direct bootup from my computer. Thanks for your time.

Your first move is to save any critical data on that drive, to some other drive.
After that, then consider 'fixing it'.

Backup your system to an external hard disk. Then save all data to an external disk. Then download the free version of HDTune from here - http://www.hdtune.com/download.html

After that download the free version of CrystalDiskInfo from here - http://crystalmark.info/download/index-e.html

Then run HDTune using an Admin account - check results (post here if you wish)
Similarly, run CrystalDiskInfo and check results.

I have bought a new external hard drive. How do i transfer / backup the files from this existing hard drive to the new hard drive? The drive is not accessible from My Computer. Can i do this from the command prompt, a sort of 'Ctrl+c' from this hard drive to "Ctrl+v' to the other?

Also, i wanted to understand what happens in a hard drive that certain files go orphaned, and then you have to run chkdsk to recover them.

So i ran the CHKDSK utility again, and this is what happened after 2 hours of it running. Very few files showed the same 'Insufficient disk space' error, but the function continued and got over this way. I am really afraid because the utilized space here shows only 1.28 TB, but i had data full upto 1.52 TB, which is almost 250 TB loss.
The drive is still not accesible from My Computer.

Please help me.

In order to use the new drive it must be formatted first. Connect it to the computer and log in with full administrator rights. The go to Control Panel ---> Administrative Tools ---> Computer Management ---> Disk Management
Go to the new disk you just connected and right click, choose Format and format it NTFS.

After doing this the disk is usable.

In order to transfer data from the old disk, the old disk data must be usable. For this you need to use RECUVA - https://www.piriform.com/recuva/download

The new drive is preformatted to NTFS.
But when i connect my old hard drive and try to run RECUVA to recover the files, the software just won't open.
As soon as i switch off the hard drive, RECUVA automatically runs. What should i do ?

Connect the old drive as a secondary (or tertiary) drive. Then run Recuva on it
