External HDD Unallocated 2047.35gb other Sol'n?

Yes, I suppose we know a bit more now.
I have the same idea, Icit2lol, I think the question asked here is how he can initialize his hard drive?
Here's where the confusion came from; MrVenJhay said the 500GB drive was external, when in reality it's internal and it's the boot drive. Below it, above the DVD-RAM, there's another hard drive that can't be listed correctly as it's model can't be detected at this point.
That makes two internal hard drives at this point, the second one, the Unknown, being around 2TB. @ MrVenJhay, can you tell us the model of the second hard drive? Is it new, or do you have information on it? If you have information on it and you don't want to lose it, tell us up front and don't do what's written below!
The drive has to be initialized, but it says it's write protected, so before all, he has to first remove the write protection from the device.
This could happen so:
1. Open Command prompt: click Start, type command, click Command Prompt
2. Type "diskpart" and press Enter
3. Type "list volume" and press Enter
4. Type select volume #, where # is the number of the drive that's giving you the "write-protected" error
5. Type "attributes disk clear readonly" and press Enter
6. Type "exit" and press Enter
These steps should make the drive read and write enabled. Then it can be Initialized, Partitioned and Formatted, like already explained. :)

Icit2lol, do you see anything else?

I don't know what volume will I choose..

Here's a Pic

This is a bit confusing, I have to admit. Without seeing all of your partitions clearly I can't tell you which volume you need to type in. You should consider it according to what the system is giving you as information.
But ICit2lol's suggestion is useful too. It's even easier, basically I've explained what's needed to be done theoretically and if the traditional way is difficult for you, then the software Icit2lol gave you would do the same but in a much easier way. I totally agree. :)
So after you manage to remove the write protection initialize your drive and everything should be fine! :)

I already tried minitool, however it does not show searched partitions it returns empty, I even tried it 2 times it took me 48hrs to finish (Lol).. Also in the pic below comparing the Disk 1 and Disk 2(which is the external that shows 2tb) disk 2 shows as bad disk and does not show other operations the only thing i can use is the wizard which is the Partition Rec, Wizard that does not return any results.

BTW.. before I was referred to this site, I used diskpart and used the clean command it was successful but still, cant use the attributes clear disk readonly, it only shows failure.. So i think there is nothing to retrieve but i will still try

maybe an idea.. download a live version of ubuntu, unplug all your hard drives inside the computer, boot the live cd and see if you can initialize and format the external drive with GParted.
